Question

The water conducting tissue generally present in gymnosperm is :

• A. Vessels
• B. Sieve tubes
• C. Tracheids
• D. Xylem fibres

Answer 1

The correct option is C

Tracheids

Explanation of the correct option:

1. Tracheids are long and elongated with blunt ends and tapered lignified cell walls in the vascular tissue of the xylem.
2. The tracheids contain pits, that are either simple or bordered.
3. Tracheids are considered the chief water-conducting elements in gymnosperms and pteridophytes.
4. The bordered pits make the way for the conduction of water and mineral salts.

Explanation of the incorrect option:

Option A - Vessels are the chief water-conducting elements in angiosperms but are absent in pteridophytes and gymnosperms.

Option B- Sieve tube transports nutrients from leaves to the rest of the plant and is the conducting element of the phloem.

Option D- Xylem fibres are called supportive functional tissue as they provide additional mechanical support.

Final answer: The water-conducting tissue generally present in gymnosperm is Tracheids

The correct option is: (C)
