Question

what is transportation how does transportation help in the absorption and transportation in plant​

Answer 1

Answer:

Food is transported through the phloem in the plants. In the transportation process, the energy from ATP is utilized to create osmotic pressure that helps in transporting food from higher concentration to lower concentration...

Transportation is a vital process in plants. Trees transport all the nutrients and water it needs for survival from its roots to the tips of the leaves.

Water Absorption In Plants:-

The water is absorbed in two ways by the plants:-

Active Absorption:

In the case of active absorption, water moves through symplast and it is absorbed according to the Diffusion Pressure Deficit changes. The rate of absorption is slow. It comprises of osmotic and non-osmotic forces.

Passive Absorption:

The rate of absorption is fast. It occurs in rapidly transpiring plants. The movement of plants is through apoplast and it is absorbed due to transpiration pull and it is created due to the stress created in xylem sap. The rate of absorption significantly depends upon the rate of transpiration. The force required for the absorption of water mainly generated in the mesophyll cells.

Transportation in Plants:-

The water and minerals are transported in plants by two types of conducting tissues:

• Xylem
• XylemPhloem

Xylem:-

Xylem is a long, non-living tube running from the roots to the leaves through the stem. The water is absorbed by the root hair and undergoes cell to cell movement by osmosis until it reaches the xylem. This water is then transported through the xylem vessels to the leaves and is evaporated by the process of transpiration.

Phloem:-

The phloem is responsible for translocation of nutrients and sugar like carbohydrates, produced by the leaves to areas of the plant that are metabolically active. It is made up of living cells. The cells walls of these cells form small holes at the ends of the cells known as sieve plates.
