Answer:
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
Explanation:
There is no defined limit on the capacity of the brain. The brain's capacity cannot be measured as it is not subject to a defined "space" where the memory is kept, and it is not such that each neuron is responsible for a single memory. The brain has complex mechanisms of memory storage, that even improve if trained.
Telomerase is fully active in germ and stem cells, but almost completely inactive in somatic cells.
<h3>What is cell?</h3>
- The smallest biological unit capable of supporting life on its own and constituting both all living entities and bodily tissues.
- The three essential parts of a cell are the cell membrane, nucleus, and cytoplasm.
- The cell membrane, which encloses the cell, controls the chemicals that enter and exit the cell.
- The nucleus, a part of the cell that contains the nucleolus, is where the majority of the cell's DNA is found.
- Additionally, the majority of RNA is produced there.
- Cytoplasm is the term for the substance that makes up a cell.
- It also features extra tiny cell parts with separate functions.
- In the cytoplasm, the majority of chemical reactions and protein synthesis take place.
- There are almost 30 trillion cells in the human body.
