Two different species of plants X and Y live together as if they are parts of the same plant Z. The plant X is an autotroph whereas plant Y is a saprophyte . The plant Y holds the cells of X in its mat of web-like hyphae and supplies water and minerals to cells of plants X . the plant X makes food by photosynthesis and shares it with plant Y
Which of the two plants, X or Y, is green in colour ?

Answer

**Step-by-Step Solution:**

1. **Identify the Characteristics of the Plants:**
- Plant X is described as an autotroph. This means it can produce its own food through the process of photosynthesis.
- Plant Y is described as a saprophyte. This means it obtains its nutrients from decaying organic matter and does not perform photosynthesis.

2. **Understand the Process of Photosynthesis:**
- Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose (food) and oxygen. The green color in plants is due to the presence of chlorophyll, which is essential for this process.

3. **Determine Which Plant is Green:**
- Since Plant X is an autotroph and performs photosynthesis, it must contain chlorophyll, which gives it a green color.
- Plant Y, being a saprophyte, does not perform photosynthesis and therefore does not have chlorophyll, meaning it is not green.

4. **Conclusion:**
- Based on the information provided, Plant X is the one that is green in color because it is capable of photosynthesis.

**Final Answer:**
Plant X is green in color.
