Why would the cells of the palisades layer have more chloroplasts in them

Because they re located in the leaves, the part of the plan with wider area to receive the sunlight

Explanation:

Palisade cells are the plant cells that contain the largest amount of chloroplast per cell, this is convenient because they can be found on leaves, the portion of the plant with a wider superficial area, this means that a larger number of chloroplasts will receive the sunlight and therefore this will benefit the photosynthesis process.

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.
