The smallest known plant having the same pigments as grasses and trees, belongs to

Options

A. Chlorophycean algae
B. Schizomycetes
C. Bryophytes
D. Angiosperms

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the smallest known plant that has the same pigments as grasses and trees. The key pigments in question are chlorophyll, which is responsible for the green color in plants and is essential for photosynthesis.

2. **Identifying the Pigments**: Grasses and trees contain chlorophyll, which is a common pigment found in many plants, including green algae. This pigment allows plants to absorb light for photosynthesis.

3. **Considering the Options**: The options provided include:
- Chlorophyceum algae
- Schizomycetes
- Bryophytes
- Angiosperms

4. **Analyzing Each Option**:
- **Chlorophyceum algae**: This is a type of green algae that contains chlorophyll and is very similar to higher plants in terms of its photosynthetic pigments and characteristics. It is also known to be the smallest known plant.
- **Schizomycetes**: These are unicellular organisms that lack chlorophyll, making them incapable of photosynthesis. Therefore, this option is incorrect.
- **Bryophytes**: These are non-vascular plants, which include mosses and liverworts. While they are plants, they are not the smallest known plants with the same pigments as grasses and trees.
- **Angiosperms**: These are flowering plants and are generally larger than algae. They do contain chlorophyll, but they are not the smallest known plants.

5. **Conclusion**: Based on the analysis, the correct answer is **Chlorophyceum algae**, as it is the smallest known plant that contains the same pigments (chlorophyll) as grasses and trees.

**Final Answer**: The smallest known plant having the same pigments as grasses and trees belongs to **Chlorophyceum algae**.
