Answer:
The importance of mitosis lies in its condition of cellular reproduction par excellence, characteristic of the vast majority of life forms that currently populate the Earth.
Explanation:
Mitosis is the cellular process by which two identical nuclei are produced in preparation for cell division. In general, mitosis is immediately followed by the equitable distribution of the cell nucleus as well as the rest of the cellular content in two daughter cells.
We all start being a cell. That is quite difficult to imagine, but it is true. And now there are about a hundred billion cells in each of our bodies, and each one has to carry the complete set of DNA instructions. That means that when cells divide, all that has to be copied by some process. And that is mitosis, where each chromosome has to be converted into a pair, and then they have to separate properly so that each of the daughter cells receives a complete set.
The correct answer is actin. Microfilaments are made form a ball-shaped protein called actin. These actins are globular proteins who are the ones responsible for the formation of microfilaments. It is mostly found in the eukaryotic cells.
The answer is; B
Meristem cells are totipotent meaning they can differentiate to any type of plant cells. Therefore they can produce a variety of plant type depending on epigenetic. However, tissue culture is derived from already differentiated cells. Therefore these cells are already determined and can only produce cell type of that plant from which they were derived.
