<h2>
Answer: C) Algae</h2>
Explanation:
By process of elimination:
- moss is a plant belonging to the Bryophyta division. It is not a protist
- paramecia are animal-like protists that don't generally photosynthesize
- protozoans feed on organic matter such as other microorganisms or organic tissues and debris (not autotrophic)
- This leaves Algae, which are autotrophic protists.
If you mean a specific system then the reproductive system...but i haven't the slightest idea as to anything else to do with your question...
The answer is all of the above
It stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include intermediary metabolism, growth, protein synthesis, and reproduction (cell division). The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
