Cellular Transport and Structure in Brief

  • Osmosis refers to the movement of water, while endocytosis involves the movement of larger substances into a cell.
  • Endocytosis leads to the production of food waste and involves the channel for Polar and Pump.
  • The cell wall prevents the passage of large molecules and facilitates bulk transport through endocytosis and exocytosis.
  • The cell wall is a non-living, rigid structure found in plant cells, composed of cellulose, galactin, manon, and calcium carbonate.
  • The cell wall provides shape, support, protection from mechanical damage, and prevents damage from macro molecules.
  • The primary cell wall is outermost, while the secondary cell wall is formed internally and does not grow.
  • Plasmodesmata are cytoplasmic connections between plant cells, while plasma desme or pore connects the middle layer of two cells.
  • The endo membrane system includes Golgi, ER, lysosomes, and vacuoles, with coordinated functions for intracellular digestion.
