Meiosis in animals produces gametes, which are the reproductive cells (sperm and egg cells) that are necessary for sexual reproduction.
Meiosis is the process by which a diploid (having two sets of chromosomes) cell divides to produce four haploid (having one set of chromosomes) cells, each with half the number of chromosomes as the parent cell.
The G1 phase (Gap 1 phase) is the period of extensive metabolic activity in the cell cycle where the cell grows, enzymes are synthesized, and DNA is replicated.
This phase is also known as the interphase or the growth phase.
Centrioles are composed of 27 microtubules arranged in a specific pattern of nine triplets (9 x 3 = 27).
These microtubules are highly stable and form a rigid structure that plays a critical role in the formation of cilia, flagella, and spindle fibers during cell division.
Facilitated diffusion is a type of passive transport that uses carrier proteins to move specific substances across the cell membrane without energy input.
This process allows cells to regulate the movement of essential molecules, like sugars and amino acids, into or out of the cell.
