1. Cell Structure

Key Concepts & Definitions

  • Cell: The basic structural and functional unit of all living organisms, capable of performing life processes.
  • Prokaryotic Cell: A simple, unicellular cell without a nucleus, e.g., bacteria.
  • Eukaryotic Cell: A complex cell with a nucleus and membrane-bound organelles, e.g., animal and plant cells.
  • Nucleus: The organelle that contains genetic material (DNA) and controls cell activities.
  • Cytoplasm: The gel-like substance within the cell membrane where organelles are suspended and biochemical reactions occur.
  • Cell Membrane: A semi-permeable membrane surrounding the cell, controlling what enters and exits.
