B the thesis statement is not the answer it is the opening question so b is false :) hope this helps.
By definition, animal cells have no cell wall -- only plant cells do. That being said, the major function of the cell wall in plant cells is to control cell pressure<span> due to …the influx and exit of water into and out of the cell. hope that helped</span>
I think you wanted to know whether the statement in question is true or false. Based on this assumption, i am answering the question. It is a true fact that cell specialization is useful because it allows multicellular organisms to divide up work. I hope the answer has helped you.
Answer:
d. secondary endosymbiosis.
Explanation:
- When a living cell acquires another organism that eventually becomes a part of this cell, this process is known as primary endosymbiosis.
- When an organism that has already undergone primary endosymbiosis engulfs another eukaryotic organism then this process is known as secondary endosymbiosis.
- Secondary endosymbiosis has been known to occur in plastids because of which they are surrounded by two membranes. This bilayer is present because one of the layers is the original outer membrane of the organism and the other membrane is that of the organism that has been engulfed.
