WebOct 21, 2024 · The fats in our bodies are like soap bubbles that go on to form vast structures of membranes in our cells that eventually become our organs. It’s the fact that these membranes are suspended in water that gives them the special properties that can be found only in living organisms, and not, for example, in a sophisticated computer.

WebHow body tissues grow. Body tissues grow by increasing the number of cells that make them up. Cells in many tissues in the body divide and grow very quickly until we become adults. When we are adults many cells mature and become specialised for their particular job in the body. So they don't make copies of themselves (reproduce) so often. WebSince cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase. Meiosis I Before entering meiosis I, a cell must first go through interphase.
