Question

Simple pits occur in:
A. Parenchyma alone
B. Simple tissue alone
C. Parenchyma and sclerenchyma
D. All types of tissues

Answer 1

Hint: Because plants are immobile, they have been given tissues made up of dead cells that provide structural support. They must contend with adverse weather conditions such as severe winds, storms, and flooding, among other things. Permanent tissues are those that have reached full maturity and have lost their ability to divide. The permanent tissues are formed when the meristematic tissues divide and differentiate.

Complete explanation:
Option A: Simple permanent tissue refers to a collection of cells that are similar in origin, structure, and function. Parenchyma, Collenchyma, Sclerenchyma, and Epidermis are the four types. Simple pits are pits that don't have any edges. A simple pit pair is made up of two simple pits that are opposite each other. On the secondary cell wall of additional xylary fibres, simple pits occur.
So, option A is not correct.
Option B: A group of cells with comparable origins, structures, and functions is referred to as simple permanent tissue. The four types are Parenchyma, Collenchyma, Sclerenchyma, and Epidermis. Pits with no borders are known as simple pits. A simple pit pair consists of two simple pits that are positioned opposite one another. Simple pits can be found on the secondary cell wall of additional xylary fibres.
Hence option B is incorrect.
Option C: Simple permanent tissue is a collection of cells with similar origins, structures, and functions. Parenchyma, Collenchyma, Sclerenchyma, and Epidermis are the four types. Simple pits are pits that have no edges. A simple pit pair is made up of two simple pits that are placed side by side. Additional xylary fibres have simple pits on their secondary cell walls.
So, option C is also not correct.
Option D: A group of cells with comparable origins, structures, and functions is referred to as simple permanent tissue. The four types are Parenchyma, Collenchyma, Sclerenchyma, and Epidermis. Pits with no borders are known as simple pits. Two basic pits are positioned side by side to form a basic pit pair. The secondary cell walls of additional xylary fibres have simple pits.
Hence option D is correct.

Hence, Option D is the correct answer.

Note:
Permanent tissues are a collection of alive or dead meristematic tissue cells that have lost their ability to divide and have been fixed in situ in the plant body. Meristematic tissues with a particular function lose their ability to divide. This is known as cellular differentiation, and it occurs when a tissue takes on a permanent shape, size, and function.
