Binary Fission - Parent cell divides - New daughter cell contains one chromosome - Carries complete/identical set of DNA (to parent) FUNGI _____________________________- Fragmentation- Hyphae - piece of organism that breaks away/ dries out - Grows into a genetically identical new organism Budding (EX- Yeast cells) - Copy of nucleus is made - Bud begins to grow on cell - Increases in size and breaks off - Becomes an indie cell SPORE- reproductive cell that could grow into a new individual through cell division Sporangium- case of spores that bursts and releases millions of spores to repopulate/spread around air currents - Can develop (temp, moisture, nutrients) ANIMALS __________________ -97% of animals are invertebrate (no backbones) BUDDING(hydra) + FRAGMENTATION + REGEN. If an animal is cut in half, the cut part will grow back, and the missing piece will grow into a new animal with the same genetically identical DNA This means that from one animal, 2 can be born. PARTHENOGENESIS Egg develops completely without being fertilized. (haploid or diploid) VEGETATIVE REPRODUCTION (does NOT involve a seed) CUTTING- If a portion of the plant is cut, the cut will grow new roots and turn into a new plant (genetically identical) SPECIALLY MOD. STEMS- Stems that run underground horizontally called runners Other plants are made on stem (reproduction) Rhizomes - similar to runners BUT grow underground -individual plants can grow (not same genetic)
