Grapevine (Vitis) possesses
(a) septate fibres
(b) very short tracheids
(c)Elongated sclereides
(d) all the above

Options

A. septate fibres
B. very short tracheids
C. Elongated sclereides
D. all the above.

Answer

To solve the question regarding the anatomical features of the grapevine (Vitis), we will analyze each option provided:

1. **Understanding the Options**:
- **(a) Septate fibres**: These are specialized fibers that have septa (partitions) within them. They provide support and elasticity to the plant.
- **(b) Very short tracheids**: Tracheids are long, narrow cells in the xylem that help in water conduction. The term "very short" suggests that this is not a typical feature of grapevines.
- **(c) Elongated sclereides**: Sclereides are a type of sclerenchyma cell that provide hardness and protection. Elongated sclereides are not commonly associated with grapevines.
- **(d) All the above**: This option suggests that all the previous statements are true.

2. **Analyzing Each Option**:
- **Option (a)**: Septate fibres are indeed present in grapevines. They provide structural support and store starch and oils, which are essential for the plant's growth and development.
- **Option (b)**: Grape vines do not typically possess very short tracheids. Instead, they have longer tracheids that are effective for water transport.
- **Option (c)**: Elongated sclereides are not characteristic of grapevines. They are more commonly found in other plant types for protection.
- **Option (d)**: Since options (b) and (c) are not applicable to grapevines, this option cannot be correct.

3. **Conclusion**: Based on the analysis, the only correct statement is option (a) - grapevines possess septate fibres.

**Final Answer**: (a) septate fibres.
