Plants: Essential Processes Terms Alternation of Generations - The fluctuation between the diploid (sporophyte) and haploid (gametophyte) life stages that occurs in plants. Angiosperm - A vascular flowering plant in which seeds are enclosed inside of protective ovaries. Archegonium - The female sex organ of terrestrial plants; where egg cells are produced. Bryophyte - A lower terrestrial plant (often a moss or liverwort) that lacks a vascular system and is dependent on environmental moisture for reproductive and nutritive functions. Bulb - Roughly spherical underground bud containing additional buds that can develop asexually into new plants. A form of vegetative propagation. Cross-pollination - The process, occurring in most angiosperms, by which the male gametes of one plant (carried by pollen grains) fertilize the eggs of another.

Unformatted text preview: Diploid - Having two sets of chromosomes, one from each parent. Double Fertilization - The mechanism of angiosperm fertilization that involves the joining of haploid gametes to create a diploid zygote, and the simultaneous joining of a second sperm cell with a fusion nucleus to create a triploid nucleus (which becomes endosperm). Endosperm - A substance, formed from a triploid nucleus in angiosperm reproduction, that nourishes a developing embryo within a seed. Fragmentation - A form of vegetative propagation in which a severed plant part develops into a whole new plant. Fusion Nucleus - The diploid product formed by the joining of the two polar nuclei in the angiosperm ovule. Gamete - A haploid sex cell (either an egg or sperm cell); male and female gametes join during fertilization to create a diploid zygote....
