What is the discus shaped structure in the cell of a green leaf?

Chloroplast

1

What is chlorophyll?

Green pigment that traps light energy

2

What is the form of energy trapped by chlorophyll and used in photosynthesis?

Light

3

What is the first stage of photosynthesis?

Light reactions

4

What is the raw material that is split into oxygen and hydrogen during the first stage?

Water

5

What is the product of the splitting of water needed for carbon fixation?

Hydrogen

6

What is the second stage of photosynthesis?

Carbon fixation

7

What is the raw material that supplies carbon atoms to be fixed into carbohydrates?

Carbon dioxide

8

What is the high energy compound that provides energy to drive carbon fixation?

ATP

9

What is the type of carbohydrate formed as a product of photosynthesis?

Sugar

10

What is the form of energy contained in carbohydrate formed by photosynthesis?

Chemical

11

What is the complex carbohydrate stored in plant cells?

Starch

12

What is the complex carbohydrate used to construct plant cell walls?

Cellulose

13

What is the general term for a factor, when in short supply, reduces or limits the rate of photosynthesis?

Limiting factor

14

What is photosynthesis?

It is the process in which green plants make their own food

15

What happens in the first stage of photosynthesis (the light reactions)?

~chlorophyll captures light energy to convert into chemical energy
~water molecules are split into hydrogen and oxygen
~oxygen is a by-product and is released into surrounding air
