Question

Which tissue is found in the pith and Cortex of stem and roots?
A) Sclerenchyma
B) Parenchyma
C) Collenchyma
D) None of the above

Answer 1

Hint: The difference between the pith and cortex is that pith is the tissue which is situated towards the vascular tissue interior to the side. Cortex is the tissue which is located between the vascular tissue layer and the epidermis. The cortex basically is located towards the outer side and pith is situated towards the inner side.

Complete answer:
Option A Sclerenchyma- sclerenchyma is one of the tissues in plants which major function includes- to provide mechanical support. Sclerenchyma is usually dead and they are long and thin tissues.
Option A is not the correct answer.
Option B Parenchyma- parenchyma are living tissues they are also thin-walled and their cortex and pith lies in the outer and inner side of epidermis.
Option B is the correct answer.
Option C Collenchyma- collenchyma are also living tissues in plants. They also provide support to plants and they come in different shapes and sizes.
Option C is not the correct answer.
Option D None of the above- this option is not applicable as one of the above options are true to the question.
Option D is not the correct answer.

Therefore, Option B is the correct answer.

Note:
Sclerenchyma contains tissues and sclerites. Sclerenchyma is dead as they have high secondary walls which are said to be lignified that are high or rich in lignin, which tends to die when they elongate or mature. Sclerenchyma is hard from the outside, that is the pith is hard and the cortex is soft. Examples of Sclerenchyma are- coconut, walnut etc.
