Biology

Front 1

Another name for the light reaction stage is:

Back 1

The light harvesting stage.

Front 2

Explain what happens in the dark reaction stage.

Back 2

This occurs in the stroma of the chloroplasts. Here the NADPH and ATP formed in the light reaction stage,are used to reduce carbon dioxide to sugars.

Front 3

What is the purpose of the NADPH?

Back 3

NADPH is used to trap the electrons.

Front 4

The purpose of the dash,is to absorb more light.

Back 4

Large surface area.

Front 5

Explain light intensity.

Back 5

In photosynthesis,light is necessary during the light reaction stage,for the production of NADPH2 and ATP. These are two important molecules that are used in the dark reaction stage to reduce carbon dioxide to sugars.

Front 6

Increasing of the light intensity will?

Back 6

Boost the speed of photosynthesis.

Front 7

Uses of glucose in plants include:

Back 7

For respiration,hence,providing it with energy.

Some of it may be converted to starch and stored in the leaf for future use.

Some if it may be used to make other organic substances such as fats and oils,cellulose,sucrose and proteins.

It is converted to a disaccharide; sucrose the form in which it is transported throughout the plant.

Front 8

What is nutrition?
