3 major function of parenchyma?

Parenchyma cells form the ground tissue of plants. Parenchyma tissues perform various important functions:

• Storage: Parenchyma cells have large intercellular space which are ideal for storage
  • High amount of starch is present in the tubers of potato and cassava
  • These can store water, fats, oil droplets, and ergastic substances
  • Store water and act as water reservoir
• Transport: Parenchyma cells transport nutrients and other chemicals
  • Transfer cells have outgrowth for increasing absorption surface
  • The xylem parenchyma helps in radial transportation of water and minerals
  • Some cells transport light from surface to underground cells
• Photosynthesis: Chlorenchyma present in the mesophyll and the other green parts of the plant, have chloroplasts and perform photosynthesis
• Gas Exchange: Aerenchyma cells help in the gas exchange
• Protection: In gymnosperms, the parenchymatous cell have spiny projections that help in the protection from predators
• Totipotent: Parenchyma cells have an ability to transform to the other types of cells and act as a precursor for other types of cells
• Buoyancy: Aerenchyma present in aquatic plants have air sacs that helps in floating
• Cuticle present on epidermis helps in reducing transpiration in water stress condition
