Bordered pits are found in
(a) Monocotyledons
(b) Gymnosperms
(c) Dicotyledons
(d) All of these

Options

A. Monocotyledons
B. Gymnosperms
C. Dicotyledons
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Bordered Pits**: Bordered pits are specialized structures found in the cell walls of certain plant tissues, particularly in xylem vessels. They are important for the transport of water and nutrients between adjacent cells.

2. **Identifying Types of Plants**: The question provides four options:
- (a) Monocotyledons
- (b) Gymnosperms
- (c) Dicotyledons
- (d) All of these

3. **Analyzing the Presence of Bordered Pits**:
- **Monocotyledons**: Generally, monocots have simpler pit structures and do not typically feature bordered pits.
- **Gymnosperms**: These plants are known to have bordered pits in their xylem vessels, which play a crucial role in water transport.
- **Dicotyledons**: Dicot plants also possess bordered pits in their xylem, similar to gymnosperms.

4. **Conclusion**: Since bordered pits are found in both gymnosperms and dicotyledons, the correct answer must include these. However, since monocotyledons do not generally have bordered pits, the best answer is (b) Gymnosperms.

5. **Final Answer**: The correct option is (b) Gymnosperms.
