Question

Choose the odd one out.
A.Xylem
B.Parenchyma
C.Collenchyma
D.Sclerenchyma

Answer 1

The plant is made up of various cells or tissues that involve various functions of the plant body. Parenchyma, collenchyma, and sclerenchyma are the ground tissue that involve various functions and provide the plants with strength and structure.

Complete answer:
To solve this question, we have to know about the tissue of plants. There are three types of cells that form the plant tissues. They function together to provide food production and storage; give flexibility, support, and strength to the plants. Parenchyma is the most flexible and thin cell found in the plants. They are responsible for the structure of plants and have many other functions like food storage, gas exchange, photosynthesis, and protection. The next cell is collenchyma; they are cylindrical in shape and give support around the cell. They consist of unevenly thickened cell walls. This cell retains the ability to process cell division once it matures. The third cell is the sclerenchyma; they lack cytoplasm and other living components get mature. They have thick and rigid cell walls; they involve in providing support to the cell and also help in transportation of materials within the cell.
So, these cells are involved in various functions of the plants and also form the structure of the plant but along with this tissue there are vascular tissues are also present that involve in the transportation of nutrients, water, and other substances in plants are carried out by tissue like xylem and phloem. Xylem is made of dead cells while phloem is made of living cells. Xylem is complex tissues that involve in the transportation of water and other nutrients to the plant while phloem is the tissue involved in the transportation of food and organic matters. The xylem tissue composed of tracheids and fiber while the phloem tissue composed of fibers, sieve cells, sieve tubes, phloem parenchyma, and companion cells. The xylem is found in the centre of the vascular bundle while the phloem tissue is found in the outer cover of the vascular bundle.
Therefore, as asked in the question the xylem is an odd one out as this is the vascular tissue while the parenchyma, collenchyma, and sclerenchyma are ground tissue.

Hence, the correct answer is option(A)

Note: Sclerenchyma cells are a form of dead cells while collenchyma cells are made of living cells. Sclerenchyma has a thickened wall and it is uniform. The cell wall is made of either cellulose or lignin or both while the cell wall of collenchyma is thick and made of cellulose.
