Robert Hooke discovered the cell in 1665, and the cell theory states that all cells arise from pre-existing cells. The cell membrane is selectively permeable and composed of lipids and proteins, with the fluid mosaic model proposed by Singer and Nicholson. Key organelles include mitochondria (powerhouse), lysosomes (suicide bag), ribosomes (protein factory), and the Golgi apparatus (packing and dispatch center). The endoplasmic reticulum (ER) aids in lipid synthesis, with smooth ER specifically involved in lipid production.
