Document Summary
A fungus is haploid for most of its life cycle. Ascomycota- the sac fungi: about 75% of all described fungal species are ascomycetes, named for the microscopic pouch where zygotes undergo meiosis to become (asco)spores. Basidiomycota- the club fungi: most commonly eaten, named for the microscopic structure where zygotes undergo meiosis to become (basidio)spores. Parasite (a) exploits the host (b), but does not kill it outright. Parasitoid (a) lives within, and eventually kills host (b) at point of metamorphosis from one life cycle stage to another. The plant receives courier service: pollinators deliver pollen (male) directly to female parts of the flower. He also feeds the anemone: competition, the gree(cid:374) a(cid:374)ole is (cid:374)ati(cid:448)e to souther(cid:374) u(cid:374)ited states. I(cid:374) the (cid:1005)96(cid:1004)"s, the brown anole was introduced from cuba. The two species vie for habitat and food resources, and it appears that the exotic. Brown anole has displaced the native green anole in some physical spaces, such as lower shrubbery and grass.
