Rhizoids are the _____ of bryophytes.

Answers

Answer 1
Answer: The answer is root hairs.

Rhizoids derive from epidermal cells of bryophytes. They are hair-like structures similar to roots of vascular plants. But, they are unicellular structures, unlike roots, which are multicellular. Not only they look alike, but they have similar functions as roots. The functions of rhizoids are the absorption of water and minerals from the soil and a support of the bryophytes.

The cerebellum is the posterior basal part of the brain below occipital lobe that related to the regulate balance.

Thinking and problem-solving are performed by the frontal lobe of the brain. It also performs emotion express and many other creative and communication-related functions.

Answers

Answer:

More sunlight is available at the surface of ocean to carry out photosynthesis.

Explanation:

Phytoplankton are autotrophic organisms and use sunlight to carry out the process of photosynthesis. Sunlight is required for photosynthesis to occur. More sunlight is available at the surface of ocean. Availability of sunlight reduces with increasing depth of water due to presence of suspended particles in water. To obtain maximum sunlight to support photosynthesis, phytoplankton are found near the surface of ocean water.
Phytoplankton require sunlight because they generate energy though photosynthesis. They do make tasty snacks for the passing aquatic organism, but not purposefully.
