Statement-l: The mesophyll of Pinus shows no distinction as spongy mesophyll and palisade.
Statement-Il: Parenchymatous cells are present in the mesophyll of Pinus.

Options

A. Both statements are correct
B. Only statement II is correct
C. Only statement I is correct
D. Both statements are false

Answer

To analyze the statements regarding the mesophyll of Pinus, let's break down the information step-by-step.

### Step 1: Understanding the Mesophyll Structure
- **Statement I**: The mesophyll of Pinus shows no distinction as spongy mesophyll and palisade.
- In most plants, mesophyll is divided into two types: palisade mesophyll (which is tightly packed and primarily involved in photosynthesis) and spongy mesophyll (which has air spaces for gas exchange).
- However, in Pinus (a genus of coniferous trees), the mesophyll does not differentiate into these two types. Instead, it consists solely of parenchyma cells.

### Step 2: Characteristics of Parenchyma Cells
- **Statement II**: Parenchymatous cells are present in the mesophyll of Pinus.
- Parenchyma cells are a type of simple tissue in plants that can perform various functions, including photosynthesis, storage, and tissue repair.
- In the case of Pinus, the mesophyll is composed entirely of these parenchymatous cells, which contain chloroplasts for photosynthesis and can store starch.

### Step 3: Evaluating the Statements
- Since the mesophyll of Pinus does not have a distinct separation into spongy and palisade mesophyll, **Statement I is correct**.
- Additionally, since parenchyma cells are indeed present in the mesophyll of Pinus, **Statement II is also correct**.

### Conclusion
Both statements are correct:
- **Final Answer**: Both Statement I and Statement II are correct.
