_______is one of the basis for classification of plants.

Options

A. Presence or absence of vascular tissue
B. Production of seeds
C. Both (A) and (B)
D. None of these

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Plant Classification**: The classification of plants is based on various characteristics that help in distinguishing different groups. One of the primary bases for classification is the presence or absence of vascular tissues.

2. **Vascular Tissues**: Vascular tissues, which include xylem and phloem, are essential for the transport of water, nutrients, and food within plants. Plants can be categorized into:
- **Non-vascular plants** (like Thalophytes and Bryophytes) which do not have these tissues. Examples include algae and mosses.
- **Vascular plants** (like Pteridophytes, Gymnosperms, and Angiosperms) which possess these tissues and are generally larger and more complex.

3. **Seed Production**: Another significant basis for plant classification is the production of seeds. Plants can be classified as:
- **Gymnosperms**: These are seed-producing plants that do not form flowers or fruits; their seeds are often exposed or "naked."
- **Angiosperms**: These are flowering plants that produce seeds enclosed within fruits.

4. **Conclusion**: Based on the characteristics discussed, both the presence/absence of vascular tissues and the production of seeds are critical bases for the classification of plants. Therefore, the answer to the question is: "Presence and absence of vascular tissue and production of seeds are both bases for classification of plants."

**Final Answer**: "Presence and absence of vascular tissue."
