Explain the following terms: (a) Plasma membrane, (b) Cytoplasm, (c) Nucleus.
Answers
Answer:
Plasma membrane : The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. ... The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell.
Cytoplasm : Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the Nucleus :
NucleusThe nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.

cytoplasm when we look at the temporary Mount of onion peel cells as well as human cheek cells we can see a large reason of each cell enclosed by the cell membranes this reason takes up very little stain it is called cytoplasm .
Nucleus the cell nucleus contains the cells gents and controls the cell growth and reproduction it has a double layered Loot Liya memories around it nucleus is usually the most prominent Orton hell in a cell the nucleus is small and around and work as the cells control centre .
plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cells contents and the outside of the cell. It is also simply called the cell membrane. That is known as plasma membrane
