Mitosis vs. Meiosis?

Question

What cells does mitosis and meiosis occur. Is in both plant and animal cells, or one of the two?

Thanks in advance!

Answer 1

Meiosis happens in sex cells (a.k.a. gametes ... in humans, sperm and egg cells). Mitosis happens in all other cells.

So if a plant or animal reproduces sexually, it has sex cells (gametes) that undergo meiosis. There are some plants, and even a few animals (like sponges), that reproduce asexually ... so there are both plants and animals that do not use meiosis. But for the most part, both plants and animals have sex cells that undergo meiosis.

All other cells, in both plants and animals undergo mitosis. There are no plants or animals that do not undergo mitosis.

Mitosis is the process of replicating DNA in normal cell replication. It produces diploid cells (cells with paired chromosomes ... the full set of chromosomes).

Meiosis is the process of dividing the DNA into sex cells. It produces haploid cells (cells with unpaired chromosomes ... half the full set of chromosomes).

Answer 2

it happens to both plant and animal cells. its the type of plant or animal cell that counts.

animal's sexual cells go through meiosis to create sperm/eggs
plant's sexual cells go through meiosis to create pollen/eggs, or whatever they do (i suck at plants sorry)

all other cells go through mitosis to create more cells, while other cells die. so when people/plants/animals grow, it isnt the number of cells, but the rate at which mitosis occurs.

Answer 3

Mitosis occur in somatic cells and meosis occurs in reproductive cells both will occur in plants and animals.
