Which of the following is synthesized in the dark-reaction of photosynthesis?
1 $\mathrm{NADPH}_{2}$
2 ATP
3 Oxygen
4 PGA
Explanation:
D Photosynthesis occurs in two phase: the light reaction and dark reaction. The formation of PGA occurs in the dark reaction of photosynthesis. It is a 3carbon compound, which is the first stable product of the calvin cycle. Light reaction occurs in grana thylakoids. Dark reaction occurs in the stroma of chloroplasts. Light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH.

The first step in dark reaction of photosynthesis is
1 formation of ATP
2 ionisation of water
3 attachment of $\mathrm{CO}_{2}$ to a pentose sugar
4 excitement of electron of chlorophyll by a photon of light.
Explanation:
C We know that the first step in the dark reaction of photosynthesis is attachment of carbon dioxide to a pentose sugar. The $\mathrm{CO}_{2}$ taken in by the plant combines a 5-carbon compound known as ribulose 1,5 bi-phosphate with two molecules of 3phosphoglycerate. This step is catalyzed by the enzyme ribulose biphosphate carboxylase.

A sleep movement is a nastic response that occurs daily in response to:
1 dark
2 light
3 both (a) and (b)
4 none of these
Explanation:
C The term "nastic response" refers to the daily response of the body to a stimulus such as light, temperature, $\mathrm{pH}$, or other factors. Nastic movements refers to the non-directional movements of plants that occur due to turgor changes.
