Question

When pollen is shed in the two-celled condition, where do the two male gametes form?

विकल्प

• Within the stigma before pollen tube formation

• Within the antipodal cells of the embryo sac

• Inside the pollen tube during its growth through the style

• Inside the ovule after pollen tube entry

Answer 1

When pollen is shed in the two-celled condition (vegetative cell + generative cell), the generative cell does not divide immediately. Instead, it remains undivided until the pollen tube has begun growing through the style, at which point the generative cell divides to form two male gametes inside the tube.
