Algae are included in

Options

A. Thallophytes
B. spermatophytes
C. Embryophytes
D. Tracheophytes

Answer

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

1. **Understanding Algae**: Algae are eukaryotic organisms that are often considered plant-like due to their ability to perform photosynthesis. They can be found in various aquatic environments.

2. **Classification of Plant Kingdom**: The plant kingdom is traditionally divided into two main sub-kingdoms: Cryptogamy and Phanerogamy. Cryptogams are seedless plants, while Phanerogams are seed plants.

3. **Categories of Cryptogams**: Cryptogams are further divided into three categories:
- Thallophytes
- Bryophytes
- Pteridophytes

4. **Identifying the Correct Category for Algae**: Algae fall under the category of Thallophytes, which are characterized by their simple structure and lack of true roots, stems, or leaves. They have a thallus-like body.

5. **Analyzing the Options**:
- **Thallophytes**: This is the correct answer, as algae are included in this group.
- **Spermatophytes**: This option is incorrect because spermatophytes are seed plants, while algae are seedless.
- **Embryophytes**: This option is also incorrect as algae do not have an embryo stage.
- **Tracheophytes**: This option is incorrect because tracheophytes are vascular plants, and algae do not fit into this category.

6. **Conclusion**: Based on the classification and characteristics of algae, the correct answer is that algae are included in Thallophytes.

**Final Answer**: Algae are included in Thallophytes.
