Spores- structures developed as a way for land plants to reproduce asexually. Spores can stay until conditions are optimal for growth. Once they find an environment conducive for growth, they develop into a new plant.

Spores- producing structures developed as a way for land plants to reproduce asexually. Spores can stay dormant until conditions are optimal for growth. Once they find an environment conducive for growth, they develop into a new plant.

Explanation:

In general terms, spore can be described as a reproductive unit that has the capability to form a new plant without sexual reproduction or fusion.The spores formed by plant species remain dormant until optimal conditions are encountered for their growth. When the conditions become optimal for the growth of a plant, the spores start developing into a new plant.

the answer is :

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.
