Question

Nondividing cells produced from meristems are called

• A. Permanent tissue
• B. Epidermis
• C. Bark tissue
• D. Parenchyma​

Answer 1

The correct option is A

Permanent tissue

The correct option is A.

Explanation for the correct option:

Option A:

1. Permanent tissue cells are formed from meristematic tissues.
2. They grow and differentiated upon maturity to perform specialized functions.
3. These cells form permanent tissues as they do not further divide.
4. The function of permanent tissues is as follows: they store the food materials such as starch, proteins, fats, and oils.
5. They show essential metabolic functions like respiration, photosynthesis, secretion, etc.
6. The permanent tissues provide rigidity to young parts of the plants.
7. Examples are parenchyma, collenchyma, and sclerenchyma.

Explanation for the incorrect options:

Option B:

1. The basal layer is the innermost layer of the epidermis and it contains small round cells called basal cells.
2. The basal cells continuously divide, and the new cells constantly push older ones up toward the surface of the skin, where they are eventually shed.

Option C:

1. The bark is the outermost layer of stems and roots of woody plants such as trees.
2. It overlays the wood and consists of three layers, the cork, the phloem, and the vascular cambium.
3. The vascular cambium is the only part of a woody stem where cell division takes place.
4. They contain undifferentiated cells that divide rapidly to produce secondary xylem to the inside and secondary phloem to the outside.

Option D:

1. Parenchyma is the simple permanent ground tissues that form the bulk of the plant tissues, such as the soft part of leaves, fruit pulp, and other plant organs.
2. They are living permanent tissues that have the ability to divide at maturity and help in the regeneration and healing of wounds.

Final answer: Nondividing cells produced from meristems are called Permanent tissue.
