What is transportation? How does it take place? How
is it useful to plants ?
Answers
Answer:
Plant transport systems move energy from leaves and raw materials from roots to all their parts. The xylem (tissue) moves water and minerals obtained from the soil to all other parts of the plants.
The plants have low energy needs, as they use relatively slow transport systems.
Plant transport systems move energy from leaves and raw materials from roots to all their parts.
The xylem (tissue) moves water and minerals obtained from the soil to all other parts of the plants.
The phloem (tissue) transports products of photosynthesis from the leaves (where they are synthesized) to other parts of the plant.
Plants have two different types of 'transport' tissue. Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant. Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots... Where as phloem transport food and required minerals..
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.
