Haplodiplontic Life Cycle
| This section does not cite any references or sources. |
In sporic meiosis (also commonly known as intermediary meiosis), the zygote divides mitotically to produce a multicellular diploid "sporophyte". The sporophyte creates spores via meiosis which also then divide mitotically producing haploid individuals called "gametophytes". Gametophytes now produce gametes via mitosis. In many plants the gametophyte is not only small-sized but also short-lived.
In the whole cycle, gametes are usually the only haploid cells, and mitosis usually occurs only in the diploid phase.
Haplodiplonts are:
- Most plants
- Some fungi

Famous quotes containing the words life and/or cycle:
“The old, subjective, stagnant, indolent and wretched life for woman has gone. She has as many resources as men, as many activities beckon her on. As large possibilities swell and inspire her heart.”
—Anna Julia Cooper (1859–1964)
“The cycle of the machine is now coming to an end. Man has learned much in the hard discipline and the shrewd, unflinching grasp of practical possibilities that the machine has provided in the last three centuries: but we can no more continue to live in the world of the machine than we could live successfully on the barren surface of the moon.”
—Lewis Mumford (1895–1990)
