Parenchyma tissue is formed in the plants for various functions. Give reason
Answers
Answer:
hey!
The parenchyma tissue is located in the soft parts of the plant such as cortex and pith. It mainly acts as a packing tissue, providing mechanical support. It also helps in the storage of food.
Answer:
Functions of Parenchyma cells
Parenchyma cells form the ground tissue of plants. Parenchyma tissues perform various important functions:
Storage: Parenchyma cells have large intercellular space which is 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 a 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 the 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 help in floating
Cuticle present on epidermis helps in reducing transpiration in water stress condition
Thick-walled parenchyma cells provide mechanical strength to the plant
Healing and regeneration: Parenchyma cells which retain their ability to divide even on maturity help in regeneration and wound healing. Tyloses present in the xylem parenchyma help in preventing damage to vascular tissues in the condition of drought.
