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:
“Luxurious Man, to bring his Vice in use,
Did after him the World seduce:
And from the fields the Flow’rs and Plants allure,”
—Andrew Marvell (1621–1678)
“Man is head, chest and stomach. Each of these animals operates, more often than not, individually. I eat, I feel, I even, although rarely, think.... This jungle crawls and teems, is hungry, roars, gets angry, devours itself, and its cacophonic concert does not even stop when you are asleep.”
—René Daumal (1908–1944)
