Answer 2

~ To reduce glucose molecules by photosynthesis, energy is required.
~ This is because the reactions ENDOTHERMIC (Take heat in).
~ The energy needed us supplied by sunlight.
~ It is trapped by the green chemical CHLOROPHYLL, which is found in chloroplasts.

Question 3

Factors affecting Photosynthesis:

Answer 3

Temperature

Carbon dioxide concentration

Light intensity

Chlorophyll concentration

Question 4

Converting Glucose:

Answer 4

Glucose provides energy for the plant.

It may be stored or changed into other things such as starch, fat, cellulose which strengthens the cell walls, proteins.

To produce proteins , the plant needs nitrate ions.
