Web14 de mai. de 2024 · Polyploidy has occurred often in the evolution of plants. The process can begin if diploid ( 2n) gametes are formed. These can arise in at least two ways. The gametes may be formed by mitosis instead of meiosis. Plants, in contrast to animals, form germ cells (sperm and eggs) from somatic tissues. If the chromosome content of a … WebWhen both homologues are present in a cell, the cell is said to be diploid; when only one is present, the cell is haploid. So, the gametes are _____, and the zygote is _____. For the diploid stage to yield a haploid stage, and hence complete the life cycle, the cell must divide. Draw two of these diploid cells. Each of these is dividing.
Web13 de dez. de 2024 · The four haploid cells produced from meiosis develop a flagellum tail and compact head piece to become mature sperm cells, capable of swimming and fertilizing an egg. The compact head, which has lost most of its cytoplasm, is key in the formation of a streamlined shape.

WebFertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote. To ensure that each zygote has the correct number of chromosomes, only one sperm can fuse with one egg. Stages of human development.
