what is the meaning of transportation in plants ?
Answers
Answer:
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.
In the case of transportation in plants, the biggest constraint is water as it ends up being a limiting factor in growth. To overcome this problem, trees and other plants have the perfect system for the absorption and translocation of water.
Plants contain a vast network of conduits which consist of xylem and phloem. This is more like the circulatory system that transports blood throughout the human body. Similar to the circulatory system in humans, the xylem and phloem tissues extend throughout the plant. These conducting tissues originate from the roots and move up through the trunks of trees. Later they branch off into the branches and then branching even further into every leaf, like spider webs.
Transportation occurs in three levels in the case of plants:
Transportation of substance from one cell to another.
Long-Distance transport of sap within phloem and xylem.
The release and uptake of solute and water by individual cells.
The flow of water and nutrients from the roots to the various portions of the plant is referred to as transportation in plants. The transfer of the food prepared by the leaves to the entire plant is also included.
In the plants, how is food transported?
- The phloem in plants transports food.
- The energy from ATP is used to produce osmotic pressure, which aids in the transfer of food from a higher concentration to a lower concentration throughout the transportation phase.
In plants, how does water move around?
- The vascular system uses conductive tissues and individual cells to convey water in plants.
- Water enters the root hairs and xylem through either apoplast or symplast channels as it travels along the water potential gradient.
- Water travels from the roots to the stem and other parts of the plant in this manner.
