The G0 Phase of the Cell Cycle While in the G0 phase, cells exist in a ... Cellular differentiation is the process in which a stem cell changes from one type to a differentiated one. Usually, the cell changes to a more specialized type. Differentiation happens multiple times during the development of a multicellular organism as it changes from a simple zygote to a complex … See more Three basic categories of cells make up the mammalian body: germ cells, somatic cells, and stem cells.

Each cell type is defined by its particular pattern of regulated gene expression. Cell differentiation is thus a transition of a cell from one cell type … See more A billion-years-old, likely holozoan, protist, Bicellum brasieri with two types of cells, shows that the evolution of differentiated multicellularity, possibly but not necessarily of animal lineages, occurred at least 1 billion years ago and possibly mainly in See more
WebOct 21, 2024 · Zygote Definition. A zygote is the first diploid cell that is formed by the fusion of male and female gametes resulting in the formation of an embryo. The zygote stage development occurs in the first week of fertilization. The genome of the zygote is the combination of DNA in each gamete and contains all the genetic information required to …
