1

What part of the plant absorbs the water?

card image

Roots

2

What is Glucose changed into before it is stored in the roots?

Starch

3

What color doesn't the Chloroplasts absorb

card image

Green

4

Where are fats and oils stored?

card image

Seeds

5

What happens when the light gets brighter?

Photosynthesis increases

6

How are roots adapted to their 'function' in Photosynthesis?

card image

Being spread out to absorb from a larger volume of soil, and root hair cells.

7

What are the advantages of root hair cells?

They have a large surface area to help absorb water quickly

8

What are the 'Xylem vessels' for?

card image

To allow the water to flow to the leaf

9

What are mineral salts dissolved in?

card image

Water

10

Why do plants need nitrates?

To make Protein

11

What does the carbon dioxide in the air diffuse through?

card image

Stomata (small holes)

12

Why does the carbon dioxide not need to go far before reaching the cells that need them?

card image

Because leaves are really thin

13

How does increasing the amount of carbon dioxide effect Photosynthesis?

It speeds it up.

14

Why do leaves have a big surface area?

card image

To catch as much sunlight as possible

15

Where does most Photosynthesis happen?

Palisade cells ( the upper surface of the leaves)

16

What is in the Palisade cells?

Chloroplasts

17

What do Chloroplasts contain?

Chlorophyll

18

What does increasing the amount of light do?

Makes photosynthesis get faster

19

Equation for Aerobic respiration

Glucose + oxygen ---> carbon dioxide + water

20

When does aerobic respiration happen?

All the time

21

When does Photosynthesis happen?

When there is light
