b ory Marvel Observation Flowering Plant Life Cycle Use Figure 10.6 as a guide to describe the life cycle of flowering plants 1. The parts of the flower involved in reproduction are the and the 2. The there the top of the same has two sacs, which produce - by meiosis. 3. Within an ovule, a megaspore mother sellepoes meliosis to produce four three of which die 4. A microspore underpoes mitosis and becomes a - the male gametophyte. 5....
