Document Summary
Bacteria can be divided into three groups: wallless bacteria, phytoplasmas, sappophytes (flowers, true bacteria. Single cell, single cell wall: filamentous bacteria. Unicellular the soil also important for parasites of plants: important because they are sacrifites and exist on the plant or in, 40% of plant disease caused by them, yeast or yeast like - eukaryotes. Single celled organisms that reproduced by budding. Original cell divided the chromosome, pinches off in the center and forms a new cell. Filamentous: hyphae is a name used for filaments, mycelium is a mass of hyphae, some have cross walls and some do not. Those that don"t have their nuclei spread out within themselves: apex or tip is wear it grows (no budding) Produce spores through specialized cells through an asexual process or through sexual process (meiosis: some never reproduce and only break off hyphae pieces. Top group is the zygomycota: produce sexual and asexual spore, sexual is called the zygospore.
