Study the diagram of a cell. Which structure is found only in plant cells and functions
in the process of photosynthesis?
W
X
Y
Z

in my knowledge

Option B: X

Explanation:

Plant cells have certain features, including chloroplasts, cell walls, and intracellular vacuoles. 

Photosynthesis takes place in chloroplasts; 

hence, X is your answer

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
