Mitosis and meiosis There are two types of cell division: mitosis and meiosis. Mitosis is the process by which body cells divide and create copies of themselves for growth and repair. In meiosis, the new cells have half the genetic material of the parent cell and is the process by which ...

The two main parts of the cell cycle include interphase and mitosis. During interphase, the cell grows and acquires the energy needed for cell division. Mitosis represents a short, but essential, component of the cell cycle. There are five basic steps associated with mitosis: Prophase: During ...
The process of gametogenesis involves some key terms which are mentioned below with brief explanation. Gametogenesis: Formation of gametes. Spermatogenesis: Sperm production. Oogenesis: Egg development. Germ Cells: Precursor cells. Mitosis: Cell replication. Meiosis: Reduction division. Primary Oocyte: ...
The centrosome functions as the main microtubule organizing center (or MTOC) of the cell. The centrosome plays a crucial role in mitosis – so much that defects in the centrosome are linked to cell growth diseases, like cancer. You'll find the centrosome only in animal cells. Plant and fung...

The shape of the ER also changes during some cell processes, such as **mitosis**. Scientists are still studying how these changes take place. A complement of proteins maintain the overall shape of the ER organelle, including stabilizing its sheets and tubules and helping determine the relative...
2. Compare and contrast the following characteristics of mitosis and meiosis: a. The type of cells that each process produces (somatic or sex cells), and the number of chromosomes that can be found in each cell (assuming human cells which have 23 pairs) b. The proportion or fraction of ...
