A few eukaryotes, notably the Bdelloid rotifers, have lost the ability to carry out meiosis and have acquired the ability to reproduce by parthenogenesis. Meiosis does not occur in archaea or bacteria, which reproduce via asexual processes such as mitosis or binary fission... Showed first 250 characters

Each of these cells contains one complete set of chromosomes, or half of the genetic content of the original cell. If meiosis produces gametes, these cells must fuse during fertilization to create a new diploid cell, or zygote before any new growth can occur... Showed next 250 characters

Ap Lab 3: Mitosis And Meiosis
The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab...

Cell Division: Mitosis And Meiosis
Explain why the process of mitosis and meiosis are both important to a living organism. When would an organism need to undergo the process of mitosis? Meiosis? What would happen if meiosis did not occur?
Mitosis is the cell process of growth and division whereas meiosis is the process of developing reproductive cells...

Meiosis vs. Mitosis:
Meiosis requires two nuclear divisions, but mitosis requires only one nuclear division. Meiosis producers four daughter nuclei, and there are four daughter cells following cytokinesis; mitosis followed by cytokinesis results in two daughter cells...

Meiosis and Mitosis
Mitosis is the process by which two daughter cells are formed, each containing a complete set of chromosomes. Mitosis is the process by which an organism creates new cells, such as skin or bone...

Meiosis is a special type of cell division that occurs during formation of sperm and egg cells and gives them the correct number of chromosomes. Since a sperm and egg unite during fertilization, each must have only half the number of chromosomes other body cells have...

Mitosis & Meiosis
Mitosis occurs exclusively in eukaryotic cells, but occurs in different ways in different species. For example, animals undergo an "open" mitosis, where the nuclear envelope breaks down before the chromosomes separate, while fungi such as Aspergillus nidulans and Saccharomyces cerevisiae (yeast) undergo a "closed" mitosis, where chromosomes divide within an intact cell nucleus...
