1. Name and describe the life cycle of plants. The plant life cycle is consisted of two parts: the gametophyte phase where it produces gametes by mitosis and the sporophyte phase which produces spores by meiosis 2. Contrast the life cycle of plants to that of animals: Typical life cycle: alteration of generation (plants)‚ diploid (animals) Resulting structure from meiosis: spores-plants‚ gametes-animals Occurrence of mitosis: gamete production-plants‚ zygote to individual-animals 3.
