Quick Revision : Cell - Structure and Functions

  • Discovery of Cell: Robert Hooke discovered cells in 1665 while observing cork under a microscope.
  • Cell Theory: All living organisms are made of cells, which are the basic structural and functional units.
  • Types of Organisms: Unicellular (single cell) and Multicellular (many cells).
  • Cell Components: Cell membrane, cytoplasm, and nucleus are the basic parts of a cell.
  • Cell Shape and Size: Cells vary in shape (spherical, spindle-shaped, branched) and size (0.1 m to 170 mm).
  • Plant vs Animal Cells: Plant cells have cell wall and chloroplasts; animal cells do not.
  • Prokaryotic vs Eukaryotic: Prokaryotes lack nuclear membrane; eukaryotes have well-defined nucleus.
  • Cell Functions: Cells perform all life processes: nutrition, respiration, excretion, reproduction.
