The waterproof layer 2 of 25 What do the epidermal cells do? Make the wax for the leaf's suface 3 of 25 What are the palisade cells designed for? Photosynthesis 4 of 25 What is the spongy mesophylll layer? Has spaces between it so carbon dioxide can reach the palisade cells 5 of 25 What else is found in the spongy mesophyll layers? Pholem and Xylem 6 of 25 What does the pholem do? Takes food made by the leaf away 7 of 25 What does the xylem do? Carries water away 8 of 25 What is the Stomata? Guard Cells that open and close for water 9 of 25 Why does a plant need a waxy cuticle? To prevent water loss, because water is needed to support the plant 10 of 25 What are the palisade cells special features? and what do they do? Tall- giving it a large surface area, which is good for absorbing carbon dioxide 11 of 25 What do palisade cells contain? lots of chloroplasts- these absorb sunlight for photsynthesis 12 of 25 If theirs lots of sunlight, what happens? Faster rate of photsynthesis 13 of 25 For photosynthesis to take place you need? Carbon Dioxide, Oxygen, Chlorophyll and Water 14 of 25 What are the limiting factors of photosynthesis? Light, Temperature, Carbon Dioxide 15 of 25 What happen if temperature is too high for photosynthesis to happen? destroys the enzymes in chlorophyll, killing the plant 16 of 25 What happens in the chloroplast? and what does it produce? A chemical reaction, making glucose 17 of 25 What is glucose? Food for the plant 18 of 25 Where is glucose made? and by what? Made in the chlorophyll, in the chloroplasts by using carbon dioxide from air and water from the roots 19 of 25 What converts in the chlorophyll? Carbon Dioxide + Water = Glucose + Oxygen 20 of 25 What happens to the oxygen after the chemical reaction has taken place? Released into the air 21 of 25 True or False: Plants use sunlight for food. False: Sunlight provides energy for the reaction to take place 22 of 25 What are the uses of Glucose? Respiration, Making Cellulose, Making Amino Acids, Making Oils and Fats and Making Starch 23 of 25 What is starch? and when is it used? A long term store of glucose and is used when there is no sunlight for photosynthesis 24 of 25 How can you test for starch? With iodine, if theirs starch present it will turn black. 25 of 25
