16. which type of plastid organelle contains a high amount of red/orange photopigments and is known to give fruits & flowers their bright coloration? a. chloroplast c. amyloplast b. chromoplast d. lypoplast

 b. Chromoplast

Explanation:

Plastids only occur in plant-like protists and are organeles surrounded by a double membrane. There are many types of plastid in plant cells. Chromoplasts include pigments different than chlorophyll and are associated with vividly colored structures and is known to give fruits & flowers their bright coloration. Plastids contain their own DNA in a small ‘plastid genome’ containing genes for some chloroplast proteins.

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.
