Angiospermic xylem consists of -
a) Vessels + Tracheids only
b) Tracheids + Fibres only
c) Vessel, tracheids, fibres and parenchyma
d) Parenchyma and fibres only

Options

A. Vessels + Tracheids only
B. Tracheids + Fibres only
C. Vessel, tracheids, fibres and parenchyma
D. Parenchyma and fibres only

Answer

To answer the question about the composition of angiospermic xylem, we can analyze the options provided:

1. **Understanding Xylem**: Xylem is a type of vascular tissue in plants responsible for the transport of water and nutrients from the roots to the rest of the plant. It also provides structural support.

2. **Components of Angiospermic Xylem**:
- **Vessels**: These are the primary water-conducting elements in angiosperms. They are more efficient than tracheids in conducting water.
- **Tracheids**: These are elongated cells that also help in water conduction but are less efficient than vessels.
- **Fibers**: These provide mechanical support and strength to the xylem.
- **Parenchyma**: These cells are involved in storage and can also assist in the conduction of water.

3. **Evaluating the Options**:
- **Option a**: Vessels + Tracheids only - This is incomplete as it does not include fibers and parenchyma.
- **Option b**: Tracheids + Fibres only - This is also incomplete as it lacks vessels and parenchyma.
- **Option c**: Vessel, tracheids, fibres and parenchyma - This option includes all the components found in angiospermic xylem.
- **Option d**: Parenchyma and fibres only - This is incomplete as it does not include vessels and tracheids.

4. **Conclusion**: The most comprehensive and correct option is **c) Vessel, tracheids, fibres and parenchyma**.

### Final Answer:
c) Vessel, tracheids, fibres and parenchyma
