BIO 311D Study Guide - Midterm Guide: Turgor Pressure, Microspore, Collagen
Document Summary
Stamen produce microspores that develop into pollen grains that contain the male gametophytes. Carpels make megaspores and their products which are the female gameteophytes. If fertilized, an ovule makes a seed. abc hypothesis a: sepals and petals b: petals and stamen c: stamen and carpels. Spores made by diploid sporophyte, meisosis hermaphrodites: posses potential to have both male and female gonads (sex organs) ex: snails, clownfish, worms, enchinoderms. Parthenogenesis: in animals, parthenogenesis means development of an embryo from an unfertilized egg cell. Most modenr plants= vascular (have extensive tubes to transport h20 and nutrients thru body) seedless vas. plants (ferns) prdocue spores spores no protective coating no food supply single celled carries 1 chromosome https://www. evernote. com/home. action#n=3e329af8 4fc2 4b00 b116 b9bcc58381ec&ses=4&sh=2&sds=5& 90% modern plants= vascular and produce seeds, making them either gymnosperms or angiosperms. Gymnosperm: seeds are not enclosed in chambers, naked seeds. Angiosperm: seeds develop inside chambers that originate within flowers, covered seeds.
