🔑 Key Concepts & Definitions

• Cell: The basic structural and functional unit of all living organisms, capable of performing life processes.
• Prokaryotic Cell: A simple cell without a nucleus, such as bacteria and archaea; characterized by a lack of membrane-bound organelles.
• Eukaryotic Cell: A complex cell with a nucleus and membrane-bound organelles, found in plants, animals, fungi, and protists.
• Organelles: Specialized structures within a cell that perform specific functions (e.g., nucleus, mitochondria, chloroplasts).
• Cell Membrane: A semi-permeable membrane surrounding the cell, controlling the entry and exit of substances.
• Cytoplasm: The gel-like substance within the cell membrane that contains organelles and facilitates cellular processes.
