Q:

Where does mitosis occur in plants and animals?

A:

Quick Answer

Mitosis occurs in almost all cells in plants and animals. It begins in the nucleus of the cell. As neurons become specialized (terminal differentiation) mitosis is switched off, so the cells can no longer reproduce.

Full Answer

When cells undergo mitosis, the end result is two genetically identical daughter cells. Any genetic mutations are random. By contrast, meiosis is a process that occurs in germ cells in the male and female gonads of plants and animals. Meiosis yields two haploid daughter cells that are not identical to the parent. Unlike mitosis, cells that undergo meiosis go through a crossing over phase where genetic material is exchanged between chromosomes. This results in genetic variation.

    What three factors limit cell size?

    A:

    Biosynthetic capacity, the nature of cell division machinery and the fact that cells grouped together form various organs and structures are factors thought to influence and limit cell size in animals. The full extent of the processes that regulate cell size are not fully understood.

    What makes onion roots ideal for studying mitosis?

    A:

    Onion roots are ideal for studying mitosis because onions have larger chromosomes than most plants, making the observation of cells easier. The roots of plants also continue to grow as they continue to search for water and nutrients. This also makes it easy to find cells in the roots of onion plants at different stages of mitosis.
