1

Limiting factors

These stop photosynthesis from stopping any faster.

2

Photosynthesis

Process where plants and algae produce food for themselves.

3

Chloroplasts

Where photosynthesis takes place.

4

Oxygen

A waste product made by plants in photosynthesis.

5

Carbon Dioxide

Absorbed by plants for photosynthesis to take place.

6

Water

Needed for photosynthesis to take place.

7

Glucose

The food plants produce in photosynthesis.

8

Chlorophyll

Inside the chloroplasts what gives the plant it's green colour.

9

Mesophyll tissue

Where the majority of photosynthesis in a plant takes place.

10

Xylem and Phloem

Transport water, mineral ions and sucrose around the plant.

11

Epidermal tissue

Covers the whole plant.

12

Limiting factor - carbon dioxide

Not enough carbon dioxide slows it down - it increases steadily until it's optimum then levels off. Light or temperature become the limiting factor.

13

Limiting factor - light

Not enough light slows it down - it increases steadily until it's optimum then levels off. Temperature or carbon dioxide become the limiting factor.

14

Limiting factor - temperature

Not enough heat slows it down - it increases until it's optimum but if it get's too hot, the enzymes become damaged and are destroyed at 45degrees. Light or carbon dioxide then become the limiting factor.

15

Greenhouse

Artificially making the ideal conditions for plants to grow at the fastest possible rate.

16

Uses of glucose - respiration

Glucose is used in respiration releasing energy enabling them to convert the rest of the glucose into other useful substances.

17

Uses of glucose - cell walls

Glucose is converted into cellulose for making strong cells walls, particularly in a fast growing plant.

18

Uses of glucose - proteins

Glucose is combined with nitrate ions from the soil to make amino acids which are made into proteins.

19

Uses of glucose - starch

Glucose is converted into starch and stored in roots, stems and leaves for when photosynthesis isn't happening, e.g. winter. It's perfect because starch is insoluble.
