Answer:
B.
Explanation:
B. is the best choice here because it is the only characteristic listed that only describes a eukaryotic cell. Both prokaryotic and eukaryotic cells have cell membranes, cytoplasm, and cillia. However, only eukaryotic cells have a nucleus to store their DNA.
Answer:
Organelles are the membrane bounded structures within a cell and they perform specific functions required for the metabolic functioning. In plant and animal cells, some of the organelles share similar functions, however, some of them are unique to each type fo cell. Here are two main examples:
- Plant cells contain chloroplasts to perform photosynthesis, but animal cells do not have chloroplast or similar strctures.
- Plant cells have one large central vacuole, but animal cells either have a scatter of small vacuoles or none.
Further, the plant cells are surrounded with the cell wall and cell membrane whereas in the animal cells, only cell membrane is present.
Answer:
Explanation:
Homeostasis and Cell Transport Homeostasis is the process by which cells maintain the internal conditions that they need to support life. This can be generalized to the heat that our bodies generate to keep us warm and support chemical reactions or the microscopic movements of molecules across cell membranes.
