Question

Transmission tissue is the characteristic feature of

• A. Wet stigma
• B. Dry stigma
• C. Solid style
• D. Hollow style

Answer 1

The correct option is C

Solid style

The correct option is C.

Explanation of the correct option:

Option C:

1. Transmission tissues are specialized tissues found in the style of the flower's carpel.
2. By forming a pollen tube connecting the stigma of the flower with the inside of the ovary, this transmission tissue helps both male and female gametes to fertilize.
3. The tissue in charge of transporting pollen from the stigma to the ovary is present in this plant. It consists of cells with delicate walls.
4. Plasmodesmata, which act as a method of binding the cells of this tube together, are present on the longitudinal and transverse walls of the pollen tube or style.

Explanation of the incorrect options:

Option A:

1. Usually, wet stigmas release an exudate that enables pollen hydration and germination to take place even with pollen from different species.

Option B:

1. Pollen adhesion and recognition frequently occur before hydration in species with dry stigmas, and these processes are well controlled.

Option D:

1. This stylar canal has glandular cells lining it.
2. The majority of these cells are multinucleated and polyploid. This part contains a variety of nutrients, including proteins and carbohydrates, and it also exhibits the action of many enzymes, including esterase and acid phosphatase.

Final answer: Transmission tissue is the characteristic feature of the solid style.
