Which cells lack living protoplasts at maturity?

a. Parenchyma

b. Companion

c. Collenchyma

d. Sclerenchyma

Expert Solution & Answer

Summary Introduction

Introduction:

Plant tissue is defined as a group of cells that carry out a specific function. It is a functional unit of the plant that connects all the organs (stems, leaves, and roots) of the plant with one another. The three basic types of the plant tissues are ground tissue that includes parenchyma, collenchyma, and sclerenchyma cells, vascular tissue that includes tracheids, vessel elements, sieve tubes, and companion cells, and dermal tissue that includes epidermal cells, trichomes and stomata.

Answer to Problem 1U

Correct answer:

Sclerenchyma cells are the thick-walled cells that lack the living protoplast at maturity. Therefore, option d. is correct.

Explanation of Solution

Reason for the correct statement:

The sclerenchyma cells are tough cells with rigid cell walls. They lack the living protoplast at maturity. They are rigid and non-living cells that provide strength to the plant.

Option d. is given as “Sclerenchyma”.

As “the sclerenchyma does not have a living protoplast at the time of maturity,” it is the right answer.

Hence, option d. is correct.

Reasons for the incorrect statements:

Option a. is given as “Parenchyma”.

Parenchyma tissues contain a living protoplast at maturity. Therefore, it is a wrong answer.

Option b. is given as “Companion”.

The protoplast is present in the companion cells at the time of maturity. Therefore, it is a wrong answer.

Option c. is given as “Collenchyma”.

Collenchyma tissues also have live protoplast at maturity. Therefore, it is a wrong answer.

Hence, options a, b, and c. are incorrect.

Conclusion

Conclusion:

The plant cells that lack living protoplasts (all the components of the plant cell excluding the cell wall) at maturity are sclerenchyma.

Students have asked these similar questions

which of the following best describes the parenchyma tissue? a. cells with moderately thick walls for flexibility b. cells with very think walls with lignin for strength and support c. cells that are long with tapered ends and cell walls with pits d. cells that long and thin with large pores at their ends e. cells with large spaces for water storage

What are cells of parenchyma tissue that contains chloroplast

Imagine a leaf of a palm tree. When it is fully grown, it must have sclerenchyma to support its size and weight. Do you think it has any sclerenchyma when it is tiny and just starting to grow? Would you expect that it might have collenchyma when it is medium sized and still growing?
