A flower’s anthers are removed before it matures. Later, pollen from another plant of the same species is dusted onto its stigma and seeds are produced. Which process has been ensured here? (i) Self-pollination (ii) Cross-pollination (iii) Fertilisation (iv) Tissue culture
View Answer
Answer: (ii) Cross-pollination
- The anthers are removed before maturing, so the flower cannot self-pollinate.
- Pollen comes from another plant of the same species and lands on the stigma — this is cross-pollination (which then leads to fertilisation).
Option
Verdict & why
(i)
Self-pollination
Wrong
— the anthers were removed, so no pollen from the same flower or plant could reach the stigma.
(ii)
Cross-pollination
Correct
— pollen came from
another plant
of the same species onto this stigma.
(iii)
Fertilisation
Wrong
— fertilisation follows later, when the male gamete fuses with the egg. The step
ensured
here is the pollen transfer.
(iv)
Tissue culture
Wrong
— that is an asexual, laboratory method. No pollen or seeds are involved.
