Meiosis in Plants and Animals
Meiosis occurs in all animals and plants. The end result, the production of gametes for sexual reproduction, is the same but the process is slightly different. In animals, meiosis is used to produce gametes directly. In most plants, meiosis is first used to produce haploid spores. These spores multiply by mitosis, developing into gametophytes, which eventually give rise to gametes. In the end, both animals and plants produce gametes with half the number of chromosomes as the parent cell.

Famous quotes containing the words plants and/or animals:
“We have been God-like in our planned breeding of our domesticated plants and animals, but we have been rabbit-like in our unplanned breeding of ourselves.”
—A.J. (Arnold Joseph)
“The vast results obtained by Science are won by no mystical faculties, by no mental processes other than those which are practiced by every one of us, in the humblest and meanest affairs of life. A detective policeman discovers a burglar from the marks made by his shoe, by a mental process identical with that by which Cuvier restored the extinct animals of Montmartre from fragments of their bones.”
—Thomas Henry Huxley (1825–95)
