Which component is not found in pholem of angiosperms?

Options

A. Albuminous cells
B. Sieve tube
C. Companion cells
D. Bast fibre

Answer

To determine which component is not found in the phloem of angiosperms, we need to analyze the components of phloem and identify the one that is exclusive to gymnosperms.

### Step-by-Step Solution:

1. **Understand Phloem Function**: Phloem is a vascular tissue responsible for the transport of food (mainly sugars) throughout the plant. It consists of various specialized cells.

2. **Identify Phloem Components**: The main components of phloem in angiosperms include:
- Sieve tubes (or sieve elements)
- Companion cells
- Phloem fibers (also known as bast fibers)
- Phloem parenchyma

3. **Analyze the Options**: The options given are:
- Albuminous cells
- Sieve tubes
- Companion cells
- Bast fibers

4. **Determine the Presence in Angiosperms**:
- **Sieve tubes**: Present in angiosperms.
- **Companion cells**: Present in angiosperms.
- **Bast fibers**: Present in angiosperms.
- **Albuminous cells**: Not present in angiosperms; these are found in gymnosperms.

5. **Conclusion**: Since albuminous cells are the only component listed that is not found in the phloem of angiosperms, the answer is albuminous cells.

### Final Answer:
**Albuminous cells** are not found in the phloem of angiosperms.
