Plant's body in thallus is

Options

A. Gymnosperms
B. Algae
C. Bryophyta
D. Pteridophyta

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks about the type of plant body that is described as "thallus." A thallus is a simple plant body that lacks true roots, stems, and leaves.

2. **Identify Plant Classifications**: In the classification of plants, there are two main categories mentioned: CryptoGams and PenderoGams. CryptoGams include primitive plants, while PenderoGams consist of higher plants.

3. **Define CryptoGams**: CryptoGams are characterized by the absence of seeds and visible organs. They include algae (also known as thallophytes), bryophytes, and pteridophytes.

4. **Focus on Algae**: Among the CryptoGams, algae are specifically noted for having a thallus-like body. This means they do not possess true roots, stems, or leaves, which aligns with the definition of a thallus.

5. **Differentiate Other Groups**: In contrast, bryophytes and pteridophytes have more differentiated structures, including true roots, stems, and leaves. This indicates that they do not have a thallus-like body.

6. **Conclude the Answer**: Based on the information, the plant body that is thallus-like is found in algae. Therefore, the correct answer to the question is "algae."

**Final Answer**: The plant body in thallus is found in algae.
