Answer:
C algal booms
Explanation:
Algal booms are harmful to the enviorment
The correct order of the following events on the mass flow of materials in the phloem is:
- Leaf cells produce sugar by photosynthesis.
- Solutes are actively transported into sieve tubes.
- Water diffuses into the sieve tubes.
- Sugar moves down the stem.
Correct answer: letter C.
This is because the mass flow of materials in the phloem must pass through all these processes in a consecutive and orderly manner, from the cell to the stem, in order to allow nutrients and other vital materials to reach from the plant roots to the leaves and fruits.
<h3>How is this transport of nutrients and other vital materials achieved?</h3>
This is accomplished by the transport of solutes through the phloem's network of channels, which contain fluids, mineral salts, vitamins and other nutrients essential to plant health. Mass flow also helps distribute oxygen and carbon dioxide to all parts of the plant. These materials are necessary for plant respiration and growth.
