1 i, ii only
2 i, ii, iii only
3 i, iii only
4 All of them
Explanation:
Photosynthesis is divided into 2 major phases - Light reaction/ Photochemical reaction or Dark reaction/ Carbon fixation reaction (Calvin’s cycle)

Photosynthesis occurs in
1 Green leaf
2 Green stem
3 Mesophyll cells
4 All of them
Explanation:
Photosynthesis does take place in the green leaves of plants (mesophyll cells) but it does so also in other green parts of the plants like green stem.

In land plants, the guard cells differ from other epidermal cells in having
1 Cytoskeleton
2 Mitochondria
3 Endoplasmic reticulum
4 Chloroplasts
Explanation:
The guard cells are bean-shaped in surface view, while the epidermal cells are irregular in shape. The guard cells contain chloroplasts, so they can manufacture food by photosynthesis (The epidermal cells do not contain chloroplasts)

Chloroplast movement is influenced by
1 Light exposure
2 Dark condition
3 Atmospheric condition
4 Number of mesophyll cells.
Explanation:
Chloroplast movement is influenced by light exposure. Light-induced changes in the cellular distribution or orientation of chloroplasts have been observed in nearly all green plants including algae, mosses, ferns, and angiosperms. Under low light conditions, chloroplasts accumulate along the cell walls that are perpendicular to the incident light. Under high light conditions, they accumulate along the walls that are parallel to the incident light. These are the regions of plant leaf cells where internal fluence rates of light are the highest and lowest, respectively and it is believed likely that the light- induced chloroplast movements serve an adaptive function.
