Meiosis is a special cell division that produces reproductive cells called gametes (sperm and eggs). It occurs in two successive stages resulting in four daughter cells, each containing half the number of chromosomes of the original cel…

The plasma membrane is a thin layer that surrounds the cell and separates it from its environment.It controls the exchange of substances such as water, nutrients, and wastes between the inside of the cell and the outside, allowing the c…

The mitochondrion is an organelle found in most eukaryotic cells. It is surrounded by two membranes: a smooth outer membrane and an inner membrane folded into cristae, which increase its surface area.The mitochondrion is the main site o…

Mitosis is a cell division process that allows a diploid mother cell (2n), meaning it contains two copies of each chromosome, to divide into two identical daughter cells, which are also diploid (2n). Each daughter cell has the same numb…
