Bryophytes resemble algae in the following aspects

Options

A. (a) Differentiation of the plant body into root,stem and heterotrophic mode of nutrition
B. (b) Thallus-like plant body, lack of vascular tissue: absence of root: and autotrophic mode of nutrition
C. (c) Thallus-like plant body, presence of roots, and autotrophic mode of nutrition
D. (d) Filamentous body: presence of vascular tissue: and autotrophic mode of nutrition

Answer

**Step-by-Step Solution:**

1. **Identify the Characteristics of Bryophytes and Algae:**
- Both bryophytes and algae are simple, non-flowering plants that share several characteristics.

2. **Thallus-like Body Structure:**
- Bryophytes have a thallus-like body, meaning they do not have true roots, stems, or leaves. Algae also exhibit a similar structure, which is why both are often referred to as thallophytes.

3. **Lack of Vascular Tissue:**
- Both groups are non-tracheophytes, meaning they lack vascular tissues such as xylem and phloem. This absence restricts their size and the environments they can inhabit.

4. **Habitat Preferences:**
- Algae can be found in both marine and freshwater environments, while bryophytes are primarily found in moist terrestrial habitats, often in shaded areas. However, some bryophytes can also thrive in aquatic environments.

5. **Autotrophic Nutrition:**
- Both bryophytes and algae are autotrophic, meaning they can produce their own food through photosynthesis due to the presence of chlorophyll and other photosynthetic pigments.

6. **Conclusion:**
- The similarities between bryophytes and algae include their thallus-like body structure, lack of vascular tissue, and autotrophic mode of nutrition.

**Final Answer:**
Bryophytes resemble algae in the following aspects:
- Thallus-like plant body
- Lack of vascular tissue
- Absence of true roots
- Autotrophic mode of nutrition
