tempArray[arrayIndex++] = "b05lfp02a | Plants have many organs, each of which has a specific function."
tempArray[arrayIndex++] = "b05lfp02b | Drag the appropriate organ names to the correct label boxes displayed and their corresponding function to the bullet point beneath."

tempArray[arrayIndex++] = "b05lfp03a | The leaf is the main site of photosynthesis and is well adapted for this function."
tempArray[arrayIndex++] = "b05lfp03b | Most leaves are thin with a large flat surface."
tempArray[arrayIndex++] = "b05lfp03c | This gives them a large surface area for absorbing sunlight."

tempArray[arrayIndex++] = "b05lfp04a | The carbon dioxide needed for photosynthesis enters the leaf through tiny pores called stomata, which are mainly in the lower surface of the leaf."
tempArray[arrayIndex++] = "b05lfp04b | The leaves are thin, so diffusion happens quickly, because the distance through which the gases have to diffuse is short."
tempArray[arrayIndex++] = "b05lfp04c | The carbon dioxide in the air spaces of the leaf is quickly absorbed into the cells and used for photosynthesis."
tempArray[arrayIndex++] = "b05lfp04d | Therefore a concentration gradient is maintained between the air outside the leaf and the air in the spaces between the leaf cells."
tempArray[arrayIndex++] = "b05lfp04e | This ensures that carbon dioxide continues to enter the leaf by the passive process of diffusion."
tempArray[arrayIndex++] = "b05lfp04f | Oxygen, which is produced as a by-product of photosynthesis, is also released into the atmosphere via diffusion through the open stomata."

tempArray[arrayIndex++] = "b05lfp05a | Leaf cells contain many chloroplasts, which in turn contain chlorophyll."
tempArray[arrayIndex++] = "b05lfp05b | Chlorophyll is a green pigment that absorbs light."
tempArray[arrayIndex++] = "b05lfp05c | Palisade cells have more chloroplasts than the cells in the spongy mesophyll layer."
tempArray[arrayIndex++] = "b05lfp05d | This is because the palisade cells are nearer the upper surface of the leaf, which therefore receives a greater intensity of sunlight."
tempArray[arrayIndex++] = "b05lfp05e | The only cells of the epidermis that contain chloroplasts are the guard cells."
tempArray[arrayIndex++] = "b05lfp05f | The epidermal cells are therefore transparent and this allows light to pass through to the chloroplasts of the cells below."
tempArray[arrayIndex++] = "b05lfp05g | Leaves have a waxy cuticle to prevent excessive water loss due to evaporation as well as some protection against being eaten by insects."

tempArray[arrayIndex++] = "b05lfp06a | The water needed for photosynthesis enters the plant via its roots."
tempArray[arrayIndex++] = "b05lfp06b | Plant roots are covered in millions of microscopic root hairs."
tempArray[arrayIndex++] = "b05lfp06c | These root hairs increase the surface area of the root for water and mineral uptake."
tempArray[arrayIndex++] = "b05lfp06d | The water and dissolved minerals then travel from the root hair cells, through the root cells to the xylem. "
tempArray[arrayIndex++] = "b05lfp06e | Xylem is a specialised tissue adapted to transport water and dissolved minerals up the stem to the leaves."
tempArray[arrayIndex++] = "b05lfp06f | Soluble products of photosynthesis, like glucose, are transported from the leaves around the plant in phloem tubes."
tempArray[arrayIndex++] = "b05lfp06g | Xylem vessels and phloem tubes are grouped together in vascular bundles."

tempArray[arrayIndex++] = "b05lfp07PQ | "

tempArray[arrayIndex++] = "b05lfp08a | What is needed for photosynthesis and what substances are produced by photosynthesis?"
tempArray[arrayIndex++] = "b05lfp08b | Select the options that are products of photosynthesis."

tempArray[arrayIndex++] = "b05lfp09a | Photosynthesis is a series of chemical reactions by which green plants make or synthesise glucose from carbon dioxide and water."
tempArray[arrayIndex++] = "b05lfp09b | Enzymes in the chloroplasts of the cells combine these two reactants using light energy from the sun."
tempArray[arrayIndex++] = "b05lfp09c | The energy is absorbed by chlorophyll."
tempArray[arrayIndex++] = "b05lfp09d | Oxygen gas is a by-product of the process and is released into the atmosphere."
tempArray[arrayIndex++] = "b05lfp09e | Click on the graphic of the leaf to view a summary of the many reactions that take place during photosynthesis."

tempArray[arrayIndex++] = "b05lfp10PQ | "

tempArray[arrayIndex++] = "b05lfp11a | To discover if a chemical reaction has taken place you can investigate whether one or more of the reactants have been used up."
tempArray[arrayIndex++] = "b05lfp11b | Or you can investigate whether one or more of the products, like glucose have been produced."
tempArray[arrayIndex++] = "b05lfp11c | The glucose produced in the initial stages of photosynthesis is rapidly turned into starch, which is insoluble."
tempArray[arrayIndex++] = "b05lfp11d | The insoluble starch granules can be stored in the leaves without affecting the osmotic balance of the cells."
tempArray[arrayIndex++] = "b05lfp11e | To discover if photosynthesis has taken place, the easiest method is to identify whether starch has been produced in the leaves."
tempArray[arrayIndex++] = "b05lfp11f | Please click on the steps numbered 1 to 4 to see how a leaf is tested for the presence of starch. Click on Next when ready to continue."

tempArray[arrayIndex++] = "b05lfp12a | In all the investigations for photosynthesis, the plant used must first be destarched, by placing it in the dark."
tempArray[arrayIndex++] = "b05lfp12b | In the dark the plant uses up any starch that has been stored in the leaves."
tempArray[arrayIndex++] = "b05lfp12c | To show whether chlorophyll is really necessary for photosynthesis you need a leaf from a variegated plant."
tempArray[arrayIndex++] = "b05lfp12d | A variegated leaf has areas of green and areas of white."
tempArray[arrayIndex++] = "b05lfp12e | The destarched plant is now left in the light for 24 hours."
tempArray[arrayIndex++] = "b05lfp12f | A leaf of the plant can then be tested to see if starch has been formed."

tempArray[arrayIndex++] = "b05lfp13PQ | "

tempArray[arrayIndex++] = "b05lfp14a | To show that light is necessary for photosynthesis, a piece of foil is wrapped around part of a leaf from a destarched plant."
tempArray[arrayIndex++] = "b05lfp14b | The plant is then left in the light for 24 hours."

tempArray[arrayIndex++] = "b05lfp15PQ | "

tempArray[arrayIndex++] = "b05lfp16a | To show carbon dioxide is necessary for photosynthesis a leaf of the plant needs to be enclosed in a flask containing potassium hydroxide, which absorbs carbon dioxide."
tempArray[arrayIndex++] = "b05lfp16b | The destarched plant is then left in the light for 24 hours."
tempArray[arrayIndex++] = "b05lfp16c | The two leaves, X and Y, are then tested for the presence of starch."

tempArray[arrayIndex++] = "b05lfp17PQ | "

tempArray[arrayIndex++] = "b05lfp18a | The glucose made during photosynthesis has many uses."
tempArray[arrayIndex++] = "b05lfp18b | It is used to provide energy for plant metabolism via respiration."
tempArray[arrayIndex++] = "b05lfp18c | Remember, respiration takes place in all living cells."
tempArray[arrayIndex++] = "b05lfp18d | The energy released in respiration is used to build more complex organic molecules. For example, energy is used to convert glucose into insoluble starch, which is stored in tubers and seeds."
tempArray[arrayIndex++] = "b05lfp18e | Energy is used to change glucose into cellulose for the plant cell walls."

tempArray[arrayIndex++] = "b05lfp19a | Some energy is used to combine glucose with nitrogen from nitrates, sulphur from sulphates and phosphorus from phosphates to make amino acids and proteins needed for growth."
tempArray[arrayIndex++] = "b05lfp19b | Proteins are needed to make enzymes, chlorophyll, cell membranes, the nuclei and cytoplasm."
tempArray[arrayIndex++] = "b05lfp19c | Some energy is used to convert glucose into lipids - fats or oils."
tempArray[arrayIndex++] = "b05lfp19d | These lipids are needed to make cell membranes and some are stored in seeds."

tempArray[arrayIndex++] = "b05lfp20PQ | "

tempArray[arrayIndex++] = "b05lfp21a | The three main factors, which affect the rate of photosynthesis, are light intensity, carbon dioxide concentration, and temperature."
tempArray[arrayIndex++] = "b05lfp21b | The overall rate of photosynthesis will be limited by the one factor that is in shortest supply."
tempArray[arrayIndex++] = "b05lfp21c | This is known as The Law of Limiting Factors."

tempArray[arrayIndex++] = "b05lfp22a | Increasing light intensity will increase the rate of photosynthesis so long as there is enough carbon dioxide and the temperature is not too cold."
tempArray[arrayIndex++] = "b05lfp22b | The factor of light intensity can be easily investigated using an aquatic plant like Elodea - Canadian pondweed."
tempArray[arrayIndex++] = "b05lfp22c | The advantage of an aquatic plant is that the rate of photosynthesis can be measured as the rate at which oxygen gas is released. The bubbles of oxygen can be easily counted and the volume measured."
tempArray[arrayIndex++] = "b05lfp22d | By changing the distance between the lamp and the plant the light intensity can be varied."
tempArray[arrayIndex++] = "b05lfp22e | The volume of oxygen given off during a set period of time, at a variety of distances, can be measured and a graph similar to this one can be drawn."
tempArray[arrayIndex++] = "b05lfp22f | The measuring cylinder containing the Elodea is placed in a large beaker of water or a water bath to keep the temperature of the water constant."
tempArray[arrayIndex++] = "b05lfp22g | This ensures that we are only measuring the effect of changing light intensity, since temperature is one of the factors that affects the rate of photosynthesis."

tempArray[arrayIndex++] = "b05lfp23a | Increasing the carbon dioxide concentration increases the rate of photosynthesis, if there is enough sunlight to provide the necessary energy and provided the temperature is not too cold."
tempArray[arrayIndex++] = "b05lfp23b | Increasing the temperature will increase the rate of photosynthesis up to the optimum temperature for the enzymes involved, provided there is still enough carbon dioxide and sunlight to provide the necessary energy."
tempArray[arrayIndex++] = "b05lfp23c | However at temperatures above the optimum the shape of the enzyme molecules will be altered. The enzymes are said to be denatured."
tempArray[arrayIndex++] = "b05lfp23d | The enzymes are no longer able to catalyse the reactions of photosynthesis and photosynthesis will slow down."

tempArray[arrayIndex++] = "b05lhp24a | Plants are living organisms and therefore the cells of all plants are constantly respiring."
tempArray[arrayIndex++] = "b05lhp24b | The respiration equation is the opposite of the photosynthesis equation."
tempArray[arrayIndex++] = "b05lhp24c | The carbon dioxide produced in respiration can be used in photosynthesis. Whether there is a net loss or a net gain of carbon dioxide by the plant will depend on the rate of photosynthesis."
tempArray[arrayIndex++] = "b05lhp24d | This depends on a number of factors, but generally the most important factor when considering the balance between photosynthesis and respiration is the light intensity."
tempArray[arrayIndex++] = "b05lhp24e | Look at the graph comparing the rate of photosynthesis and the rate of respiration."
tempArray[arrayIndex++] = "b05lhp24f | When respiration and photosynthesis are balanced, there is no net gain or loss of carbon dioxide or oxygen. This is called The Compensation Point."

tempArray[arrayIndex++] = "b05lhp25PQ | "

tempArray[arrayIndex++] = "b05lfp26a | Plants need more than carbon dioxide and water to thrive."
tempArray[arrayIndex++] = "b05lfp26b | For healthy growth, plants need several mineral elements as well. These elements are dissolved in soil water in the form of mineral ions, and are taken into the roots by two processes - diffusion and active transport."
tempArray[arrayIndex++] = "b05lfp26c | For example, nitrogen is taken in through plant roots as nitrate ions, phosphorus as phosphate ions and potassium as potassium ions."
tempArray[arrayIndex++] = "b05lfp26d | Fertiliser bags usually carry a code of three numbers, such as 10:10:27."
tempArray[arrayIndex++] = "b05lfp26e | These numbers show the amount of the three main nutrients or macronutrients that plants need to survive and grow well."
tempArray[arrayIndex++] = "b05lfp26f | These three nutrients are known as the NPK content."
tempArray[arrayIndex++] = "b05lfp26g | There are other minerals needed in much smaller amounts, these are called micronutrients, for example magnesium needed to make chlorophyll."

tempArray[arrayIndex++] = "b05lhp27a | If a plant is deprived of these minerals, it develops defects called mineral deficiency symptoms."
tempArray[arrayIndex++] = "b05lhp27b | Plants need nitrogen to make amino acids and proteins to grow leaves and shoots."
tempArray[arrayIndex++] = "b05lhp27c | Plants need phosphorus to make enzymes for respiration and photosynthesis, DNA and other proteins for growth."
tempArray[arrayIndex++] = "b05lhp27d | Plants need potassium to make flowers and fruits and magnesium to make chlorophyll."

tempArray[arrayIndex++] = "b05lfp28PQ | "
