First land plant was represented by

Options

A. (a) Ferns
B. (b) Grasses
C. (c) Gymnosperms
D. (d) Algae.

Answer

### Step-by-Step Solution:

1. **Understanding Plant Evolution**: The question asks about the first land plant. To answer this, we need to understand the evolution of plants and their classification.

2. **Identifying Plant Groups**: The major groups of plants are:
- **Thallophyta**: This group includes algae, which are aquatic and therefore not considered land plants.
- **Bryophytes**: These are the first land plants but are still dependent on water for reproduction, making them not true land plants.
- **Pteridophytes**: This group includes ferns, which are true land plants as they do not require water for fertilization and possess vascular tissues.
- **Gymnosperms**: These are seed-producing plants that do not produce flowers or fruits.
- **Angiosperms**: These are flowering plants that produce seeds enclosed in fruits.

3. **Evaluating the Options**:
- **Option A: Ferns** (Pteridophytes) - These are true land plants that do not need water for fertilization.
- **Option B: Grasses** (Angiosperms) - These are more advanced plants and not the first land plants.
- **Option C: Gymnosperms** - While they are seed plants, they are not the first land plants.
- **Option D: Algae** (Thallophyta) - These are aquatic and cannot be considered land plants.

4. **Conclusion**: Based on the classification and evolution of plants, the first true land plants are represented by ferns (Pteridophytes). Therefore, the correct answer is **A. Ferns**.
