Question

Hydrostereom or transfusion tissue is found in

• A. Gymnosperm roofs
• B. Gymnosperm leaves
• C. Gymnosperm stems
• D. All the above

Answer 1

The correct option is B

Gymnosperm leaves

The correct option is B.

Explanation of the correct option:

1. Gymnosperm leaves contain hydrostereom, also known as transfusion tissue.
2. Plants have a circulatory system that allows them to conduct and transport diverse elements throughout their bodies.
3. As a result, they have a well-managed venous system consisting of a system, phloem, tracheid, vessels, and so on.
4. Transfusion tissue includes non-lignified living parenchyma with walls and thin-walled but lignified tracheids with bordered pits.
5. A replacement for an actual vein and veinlets system is hydrostereom.
6. However, such a plant retains traditional vascular bundles that run throughout its body, such as live but non-lignified parenchymatous cells and lignified tracheid arteries.
7. Because it is primarily involved with the movement of food inside the plant body, it is found in the leaves.
8. This type of leaf has hydrostereom veins that carry the food produced by the leaves to other areas of the plant body.

Explanation of the incorrect option:

Option A and Option C:

Gymnosperm roofs and Gymnosperm stems do not contain transfusion tissue.

Final answer: Hydrostereom or transfusion tissue is found in Gymnosperm leaves.
