🔑 Key Concepts & Definitions

  • Cell: The basic structural and functional unit of all living organisms, capable of performing life processes independently or as part of a multicellular organism.
  • Prokaryotic Cell: A simple, unicellular cell without a nucleus, such as bacteria; characterized by a cell membrane, cytoplasm, and genetic material directly in the cytoplasm.
  • Eukaryotic Cell: A larger, complex cell with a defined nucleus and membrane-bound organelles, found in plants, animals, fungi, and protists.
  • Organelles: Specialized structures within eukaryotic cells, such as mitochondria (energy production), chloroplasts (photosynthesis), ribosomes (protein synthesis), and the nucleus (genetic control).
  • Cell Membrane: A thin, flexible barrier surrounding the cell, controlling the entry and exit of substances.
  • Stamceller (Stem Cells): Undifferentiated cells capable of dividing and developing into specialized cell types, essential for growth and repair.
