Do all eukaryotic cells have only 1 nucleus? Explain. Why is the nucleus known as the brain of a cell? What kinds of molecules enter and leave the cell nucleus? For what purpose? State any three parts of a cell and describe their functions. (a) What cell structures are ch...
Do all cells have a nucleus? Not all cells have a nucleus. Biology breaks cell types into eukaryotic (those with a defined nucleus) and prokaryotic (those with no defined nucleus). You may have heard of chromatin and DNA. ... If you don't have a defined nucleus, your DNA is probably...
Cells are also capable of reproduction, with new daughter cells arising from parent cells. In multicellular organisms, cells that perform similar functions group together to form tissues.Answer and Explanation: Cells that lack a nucleus and other membrane-bound organelles, such as mitocho...
- Eukaryotic cells are more complex, can be unicellular or multicellular, and have a defined nucleus and membrane-bound organelles. Examples include plant and animal cells. 2. Characteristics of Prokaryotic Cells: - Prokaryotic cells do not have a nuclear membrane. Their genetic material (DNA) is...
If the DNA within a cell is not separated from the cytoplasm, then that cell is a prokaryote. All known prokaryotes, such as bacteria and archaea, are single cells. In contrast, if the DNA is partitioned off in its own membrane-bound room called the nucleus, then that cell is a ...
1. What are cells with an enclosed nucleus called? What are the main elements of the nucleus? 2. Do all eukaryotic cells have only one nucleus? What membrane-bound compartments are found in a eukaryotic cell? What is the plasma membrane and its structure...
These cells secrete antibodies (2 possible answers). Adaptive Immunity: Adaptive immunity is a term that describes the specific immune system which deals with specific invading pathogens including bacteria and viruses. There are many specialized white blood cells including ...
Not all cells have a membrane-bound nucleus. Eukaryotic cells (including plant cells and animal cells) have nuclei and membrane-bound organelles, while prokaryotic cells (i.e. bacteria) do not. Nuclei contain information needed for protein synthesis and so control the activities of the whole ...
What is one main way in which prokaryotic and eukaryotic cells differ? a) Prokaryotic cells have a nucleus and eukaryotic cells do not. b) Prokaryotic cells have membrane-bound organelles and eukaryotic cells do not. c) Eukaryotic cells have a nucleus and ...
What do plant cells have that animal cells do not? What are the main structures within the cell nucleus? What are the main structures within the nucleus of a cell? What cell organelles are involved in cell division? What are all the secretory cells in the body?
