Question 1

photosynthesis meaning

Answer 1

the process by which plants produce carbohydrates from carbon dioxide and water using energy from light

Question 2

chlorophyll

Answer 2

green pigment present in the chloroplasts of plant cells

Question 3

uses and storage of carbohydrates

Answer 3

as an energy source: broken down into energy by respiration

storage: glucose is converted into sucrose and then transported in the phloem to different parts of the plant. Returning back to glucose when needed

Structural support: some of the glucose is converted to cellulose, which is an important component in the plant’s cell walls

Question 4

chemical equation for photosynthesis

Answer 4

6CO2 + 6H2O —(light +chlorophyll) —> C6H12O6 +6O2

Question 5

limiting factors for photosynthesis

Answer 5

CO2 conc., light intensity and temperature
