Hii!!

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin

● The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Hope this helps!! if it has pls mark me as the brainliest Xd :D

The phenomenon of single or double fertilization is unique to the seed plants
Ksju [112]

Answer:

Double fertilization

Explanation:

The phenomenon of double fertilization is unique to flowering plants (i.e., angiosperms). Each pollen grain produces two male gametes (sperm cells), one of which fertilizes the egg to form the zygote, whereas the other sperm fuses with polar nuclei in the female gametophyte in order to form a triploid cell (3n) called endosperm. Subsequently, this endosperm will support embryonic growth by supplying storage nutrients and by serving as a mechanical barrier during seed development and germination.
