The life cycle is important in managing insects because the habitat, habits and appearance of an insect may change dramatically through the course of a life cycle, depending on the form of life cycle. Managing insects with complete metamorphosis may require different tactics to target immature and adult stages.

A zygotic meiosis is a meiosis of a zygote immediately after karyogamy, which is the fusion of two cell nuclei. This way, the organism ends its diploid phase and produces several haploid cells. The individuals or cells as a result of mitosis are haplonts, hence this life cycle is also called haplontic life cycle.

What are the three parts of a seed?

The three primary parts of a seed are the embryo, endosperm, and seed coat. The embryo is the young multicellular organism before it emerges from the seed.
