Question

Pollen tube develops from

• A. Vegatative nucleus
• B. Vegetative cell
• C. Generative cell
• D. Male gametes

Answer 1

The correct option is B Vegetative cell

Pollen is produced by the stamen, the male reproductive organ of the flower. Each pollen grain contains a vegetative cell and generative cell. The vegetative cell produces the pollen tube, a tubular protrusion from the pollen grain which carries sperm cells within its cytoplasm. The germinated pollen tube must then enter in the nutrient-rich style and curl to the bottom of the ovary to reach the ovule. Once the pollen tube reaches the ovule, it burst to deliver the two sperm cells.

So, the correct answer is 'Vegetative cell'.
