Plant have no circulatory system then how sales manager intracellular transport
Answers
Answer:
Plants lack a well developed circulatory system like animals.
Explanation:
But, plants have vascular tissues comprising of xylem and phloem. The xylem carries water and minerals from the soil to the photosynthesizing parts of plants against the gravity. And, phloem transports the prepared food to the storage organs as well as to cells needing it.
And the intracellular local transportation is carried out by plasmodesmata which is a cytoplasmic connection between adjacent cells, leading to the exchange of materials.
Plants have no circulatory system yet they manage to transport water minerals and food material through xylem and phloem. (Long distance transportation)
Xylem conduct water and minerals from roots to different part of shoot.
Xylem become functional only after the death of its component and degeneration of protoplasm to produce lumen which carries water.
It is made up of four types of cell - xylem tracheid, xylem vessel, xylem fibre (dead) and xylem parenchyma (living)
Phloem helps in the conduction of food from the leaves to various part of the plant. It is made up of four types of cell - seive tube, companion cell, phloem parenchyma (living) and phloem fibre (dead).
Short distance transportation of materials occur from one cell to other or intracellular transportation occur through plasmodestmata.
