Mainly comparison in xylem and phloem
Answers
Answer:
Xylem is the complex, dead and tissue play its role in transporting the food and other organic material produced by the green parts especially leaves by the process of photosynthesis.
Xylem and phloem are the two types of vascular tissues , present in plants and together constitute vascular bundles. Their function is to efficiently transport the materials which can be food, water, nutrients, organic materials, etc. between the stems, roots, and leaves of plants.
Key Differences Between Xylem and Phloem
Given below are the important points which distinguish xylem with that of phloem:
1. Xylem is the complex tissue of plants , responsible for
transporting water and other soluble nutrients to the plants and the flow is unidirectional which is from root to the upper part of the plant, while on the other hand phloem is the another kind of the vascular, living tissue which is responsible for
transporting food and other organic materials, prepared by the green parts of the plants like leaves. The flow of material in phloem is
bi-directional .
2. Xylem mainly made up of dead cells and parenchyma is the only living cells present, whereas phloem mainly contains living cells and fibers are the only dead cells.
3. Xylem is found in the center of the vascular bundle, deep in the plant and made up of xylem vessels, fiber, and tracheids, whereas phloem is found on the
outer side of the vascular bundle and made up of phloem fibers, sieve tubes, sieve cells, phloem parenchyma and companion cells.
4. Xylem transports only minerals and waters from the roots, and also provide mechanical strength to the plant, on the contrary phloem transports food materials that are prepared by the green parts of the plants to other parts but is incapable of providing mechanical support to the plant.
5. Xylem often constitutes the bulk of the plant body, but the conducting cells or tracheary cells are dead, while phloem forms a small part of the plant body and the conducting cells are living.

Answer:
XYLEM:
xylem provide water and minerals to plants.xylem tubes are dead. they are in star shape.
PHLOEM:
phloem provide food and sugar to plant. phloem tubes are alive. they are not star shaped.
