Question

The tissues that are originated from meristematic tissues are called ____.

• A. Secondary tissues
• B. Intercalary tissues
• C. Simple tissues
• D. Permanent tissues

Hint:

Remember the core lifecycle pathway equation: $$\text{Meristematic Tissue} \xrightarrow{\text{Differentiation}} \text{Permanent Tissue}$$ This transformation defines how a plant transitions from active cellular growth to structural maturity.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The cellular life cycle in plants involves a process called differentiation, where dividing meristematic cells undergo changes to fit specific functional biological assignments.

Step 2: Detailed Explanation:
When newly formed cells produced by the active divisions of meristematic tissues lose their protoplasmic division capability, they undergo structural changes in their cell walls and shapes. This structural maturation process is called differentiation. The resulting specialized, stable cells that form the structural body framework of the plant are collectively called permanent tissues. These can later be further classified into simple or complex configurations.

Step 3: Final Answer:
Tissues that differentiate and originate from meristematic cells are called permanent tissues.

Answer 2

This question is about what happens to cells once they are produced by a meristem and stop dividing, so we need to find the term that specifically names that end-state, rather than a term describing a sub-type, position, or complexity level.

1. Secondary tissues: refers only to tissue produced during a later phase of growth (secondary growth, such as from vascular or cork cambium); it is one specific subset, not the general name for all tissue derived from meristems.
2. Intercalary tissues: is not a standard term for differentiated tissue at all; "intercalary" instead describes a position of certain meristems (found between mature tissues), so this does not name the resulting mature tissue.
3. Simple tissues: describes tissue made of just one cell type (like parenchyma or collenchyma) and is a sub-category based on cellular composition, not the general term for all tissue that differentiates from meristem.
4. Permanent tissues: is the general name given to any tissue whose cells have lost the ability to divide and have taken on a fixed shape and function after differentiating from meristematic cells; this directly matches the description in the question of tissue "originating from" meristems.

Since the question is asking for the broad, general name of differentiated tissue rather than any of its narrower subtypes, only one option fits.

Therefore, the correct answer is Permanent tissues.
