The xylem in plants are responsible fora)transport of water.b)transport of food.c)transport of amino acids.d)transport of oxygen.Correct answer is option 'A'. Can you explain this answer?

Question

Answer

The main function of xylem is to transport water, and some soluble nutrients including minerals and inorganic ions, upwards from the roots to the rest of the plant. Xylem cells form long tubes that transport materials through xylem sap. These substances are transported through passive transport, so the process doesn’t require energy. The phenomenon that allows xylem sap to flow upwards against gravity is called capillary action!!

Answer

Xylem helps to transport nutrients to plant from soilwith water so opt a is correct : )

Answer

Water transportation

Answer

Transport of Water by Xylem in Plants

The xylem is a specialized tissue in plants that is responsible for transporting water and minerals from the roots to the leaves and other parts of the plant. This process is known as transpiration. The xylem is made up of two types of cells: tracheids and vessel elements.

Structure of Xylem

Tracheids are long, narrow cells that are found in all vascular plants. They have thin walls and are tapered at both ends. Vessel elements, on the other hand, are wider and shorter than tracheids. They have thick walls and are arranged end to end to form a continuous tube-like structure.

Transport of Water

The movement of water through the xylem is driven by transpiration, which is the loss of water vapor from the leaves. As water is lost through tiny pores on the surface of leaves, called stomata, it creates a negative pressure or tension in the xylem. This tension pulls water up from the roots and through the xylem to the leaves.

The cohesion-tension theory explains how water molecules stick together due to hydrogen bonding and how this creates a continuous column of water molecules in the xylem. The tension created by transpiration pulls the column of water up through the xylem.

Conclusion

In conclusion, the xylem in plants is responsible for the transport of water from the roots to the leaves and other parts of the plant. This process is driven by transpiration and is essential for the survival of the plant.

Answer

Xylem

tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds. Phloem is

responsible for

transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems.

Answer

Xylem tissues include tracheids, vessels, fibres and parenchyma and serve in the ascent of sap/water and minerals. Phloem tissues is a composed of four elements namely, sieve elements, companion cell, phloem fibres and phloem parenchyma and serve in translocation of organic nutrients. Transfer RNA (tRNA) serve as carrier RNA and transports amino acids from cell pool to the mRNA bound to the ribosome where the protein is being synthesized. Haemoglobin molecule contains four polypeptide chains and four heme prosthetic groups. It serves as a carrier of oxygen gas.

So, the correct answer is option A.

Answer

Correct option is A because xylem is a tissue which transports the water and minerals from root to the shoot.

Answer

Obviously.. option a is right

xylem is responsible for transport of water
And phloem for transport of food.....
