Document Summary
Bacteria fossils were found to have dated back to 3650 mya. Green algae were discovered to be the first group of plants. The angiosperms are the largest branch of plants: the bryophytes are second largest, ferns, lycophytes, and then gymnosperms. Bryophytes require moist environments (ex. mosses) in order to do photosynthesis. Liverworts are flattened plants that develop reproductive structures start off as males and then slowly develop into females. The cycle of the haploid and diploid generation varies between different species/groups of plants (cycle is present in all plants, just different lengths of the cycle) The spermatozoid swims over and requires a thin film of water: senses the female archegonium. The zygote develops in the archegonium and grows out of the archegonium: after it grows, it creates haploid spores in the capsule which it releases afterwards. Spore grows into protonema which develops into the gametophyte: some become male and some become female (50/50)
