Question
During the process of embryogenesis, which cellular process
is primarily responsible for increasing the number of cells in the developing embryo?Solution
Embryogenesis is the developmental process where a zygote transforms into an embryo. During this critical phase, the zygote undergoes repeated rounds of mitosis to increase cell numbers while maintaining the diploid chromosome complement. Simultaneously, these cells undergo differentiation to form specialized tissues and organs. Mitosis is essential for growth and development, while meiosis is associated with gamete formation, binary fission occurs in prokaryotes, and sporulation is a survival mechanism in certain microorganisms.
