Animal Cells: A Microscopic World
Structure and Function
Essential Building Blocks of Life
Animal cells, the fundamental units of life for all animals, are complex structures teeming with specialized organelles that perform crucial functions. These microscopic marvels are enclosed within a thin, flexible membrane that regulates the movement of substances into and out of the cell. At the core of the cell lies the nucleus, the control center that houses the cell's genetic material. Surrounding the nucleus is the cytoplasm, a gel-like substance that houses numerous organelles, including mitochondria (which generate energy), endoplasmic reticulum (involved in protein synthesis), Golgi apparatus (responsible for processing and packaging proteins), and lysosomes (which break down waste materials).
