- In plants, variations in the epochs of the life cycle are often centred around the times of fertilization and meiosis. After fertilization the organism has the diploid number of chromosomes (diplophase); after meiosis it is haploid (haplophase). The two events vary in time with respect to each other.

Differentiate between sexual and asexual reproduction in plants; Explain alternation of generations in ferns and contrast that to the life cycle of angiosperms (flowering plants). Describe the structure and function of the flower and the fruit within the angiosperm life cycle.
Oct 19, 2023 · Plant and Animal Reproduction. While all organisms reproduce, not all organisms reproduce the same way. Explore the similar and different ways that plants and animals pass on their genes.
In many plant groups, fragmentation of the plant body, followed by regeneration and development of the fragments into whole new organisms, serves as a reproductive system. It is common horticultural practice to propagate desirable varieties of garden plants by means of plant fragments, or cuttings.
Identify key features of an organism’s life history and how those life history traits respond to the environment and to natural selection. Calculate population (net) reproductive rate from life tables to determine if a population is growing or shrinking.
