1
Q

Limiting factors

A

These stop photosynthesis from stopping any faster.

2
Q

Photosynthesis

A

Process where plants and algae produce food for themselves.

3
Q

Chloroplasts

A

Where photosynthesis takes place.

4
Q

Oxygen

A

A waste product made by plants in photosynthesis.

5
Q

Carbon Dioxide

A

Absorbed by plants for photosynthesis to take place.

6
Q

Water

A

Needed for photosynthesis to take place.

7
Q

Glucose

A

The food plants produce in photosynthesis.

8
Q

Chlorophyll

A

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

9
Q

Mesophyll tissue

A

Where the majority of photosynthesis in a plant takes place.

10
Q

Xylem and Phloem

A

Transport water, mineral ions and sucrose around the plant.

11
Q

Epidermal tissue

A

Covers the whole plant.

12
Q

Limiting factor - carbon dioxide

A

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
Q

Limiting factor - light

A

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
Q

Limiting factor - temperature

A

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
Q

Greenhouse

A

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

16
Q

Uses of glucose - respiration

A

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

17
Q

Uses of glucose - cell walls

A

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

18
Q

Uses of glucose - proteins

A

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

19
Q

Uses of glucose - starch

A

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.
