B2 Chapter 2 Photosynthesis and transpiration 0.0 / 5 ? BiologyPhotosynthesis and transpirationGCSEAQA Created by: ColdAsteroidCreated on: 15-12-15 21:55 Which of the organelles are in a plant cell as well as an animal cell? Nucleus; Cytoplasm; Cell membrane 1 of 22 What organelles are in plant cells only? Cellulose cell wall; permanent vacuole; chloroplasts 2 of 22 What does the cell wall do? Gives strength/rigidity 3 of 22 What liquid does the permanent vacuole contain? Cell Sap 4 of 22 What liquid do the chloroplasts contain and what do they do? Chlorophyll; it traps light during photosynthesis. 5 of 22 What is the equation for photosynthesis? (6)CO2 + (6)H2O --> C6H12O6 + (6)O2 6 of 22 What is the glucose used for in a plant? (Tip: Starch) Starch for use at night 7 of 22 Glucose Cellulose for plant cell wall 8 of 22 Glucose Turned into fats and oils for storage 9 of 22 Glucose Combined with nitrates from soils to make proteins. 10 of 22 Glucose Respiration 11 of 22 What is a tissue? Group of identical cells working together for a function 12 of 22 What is an organ? Group of tissues working together to carry out a function 13 of 22 Give examples of plant organs. Stem, roots, and leaves. 14 of 22 How do we increase the rate of photosynthesis? more CO2, artificial light, keep plants optimum temp.(enzymes) 15 of 22 What is happening if photosynthesis is slow? There must be a limited factor (something in short supply) 16 of 22 If light intensity is not a limiting factor, what should you increase? Carbon dioxide/temperature. 17 of 22 If Carbon dioxide is not a limiting factor, what should you increase? Temperature/light intensity 18 of 22 If temperature is not a limiting factor, what should you increase? Carbon dioxide/light intensity 19 of 22 Why should temperature not be increased above the optimum temperature? Enzymes will denature and photosynthesis will slow down. 20 of 22 Why is an oil burner used in a greenhouse? -Adds more CO2, -Higher temp. Photosynthesis rate increases 21 of 22 How can we increase the light intensity of the greenhouse? Use a lamp that is usually switched on all the time. 22 of 22
