Question

Prosenchyma is a type of ____.

• A. Chlorenchyma
• B. Collenchyma
• C. Sclerenchyma
• D. Parenchyma

Hint:

Remember the prefix connection: Prosenchyma is Parenchyma that wanted to look like a fiber! It keeps its living protoplast but stretches out to provide structural support.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Simple permanent plant tissues are composed of similar types of cells executing a collective structural or physiological task, and can modify into various sub-types based on shape and function.

Step 2: Detailed Explanation:
Prosenchyma is a specialized modification of parenchyma tissue. While standard parenchyma cells are typically isodiametric (spherical or oval) with thin walls, prosenchyma cells are significantly elongated or fiber-like with pointed ends and can develop slightly thickened cell walls. Their primary function shifts from mere storage to providing temporary mechanical support and strength to the vascular regions of the plant.

Step 3: Final Answer:
Prosenchyma is a structural variation of Parenchyma tissue.
