Binary fission
1. Forms two daughter individuals
2. Divides only once
3. No residue is left
4. Takes place in favourable conditions
5. Immortality is present
Example: Amoeba reproduces by binary fission
Multiple fission
1. Forms many daughter individuals
2. Divides repeatedly
3. Residue is left
4. Takes place in favourable as well as unfavourable conditions
5. Immortality is absent
Example: Plasmodium reproduces through multiple fission
Lymphocytes that destroy foreign cells or virus- infected cells are cytotoxic T cells.
<h3>What is cytotoxic T cell?</h3>
- A particular class of immune cell that is capable of eliminating specific types of cells, such as virus-infected cells, cancer cells, and alien cells.
- To destroy cancer cells, cytotoxic T lymphocytes can be isolated from other blood cells, cultured in a lab, and then administered to a patient.
- White blood cells and lymphocytes both fall under the category of cytotoxic T lymphocytes.
- It is also known as a killer T cell and a cytotoxic T cell.
- The helper T cell and the cytotoxic T cell are the two main subtypes of T cells.
- Helper T cells, as their names imply, "assist" other immune system cells, whereas cytotoxic T cells "kill" virally-infected cells and tumours.
- The TCR cannot directly bind antigen, unlike an antibody.
