Answer:

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

Explanation:

Now this is a lot of bio to cover, but, there are 5 stages of mitosis.

1) Interphase:

The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?

Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.

During interphase, microtubules extend from these centrosomes.

2. Prophase:  

The chromosomes condense into X-shaped structures that can be easily seen under a microscope.

Each chromosome is composed of two sister chromatids, containing identical genetic information. This is very important.  

The chromosomes pair up so that both copies of chromosome 1 are together, both copies of chromosome 2 are together, and so on.

At the end of prophase the membrane around the nucleus in the cell dissolves away releasing the chromosomes.

The mitotic spindle, consisting of the microtubules and other proteins, extends across the cell between the centrioles as they move to opposite poles of the cell.

3. Metaphase:

The chromosomes line up neatly end-to-end along the Centre (equator) of the cell.

The centrioles are now at opposite poles of the cell with the mitotic spindle fibers extending from them.

The mitotic spindle fibers attach to each of the sister chromatids.

4. Anaphase:

The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.

5. Telophase:

At each pole of the cell a full set of chromosomes gather together.

A membrane forms around each set of chromosomes to create two new nuclei.

The single cell then pinches in the middle to form two separate daughter cells each containing a full set of chromosomes within a nucleus. This process is known as cytokinesis.

Plant reproductive seeds are not enclosed nor found on cones or similar structures. These seeds are referred to as ___________.
Fittoniya [83]
The appropriate answer is e. gymnosperm. Gymnosperms have seeds that are not protected by an ovary or fruit. A popular example of a gymnosperm are conifers. Another characteristic of gymnosperms is that they do not have bright flowers. The Greek word for gymnosperm literally translates to naked fruit. The seeds of these plants are open to the air and as such they are directly pollinated by the wind.
