Read the given passage and answer the questions that follow:-
Plant breeders aim to create new and improved varieties by crossing different species, and sometimes even genera, to combine desirable traits. To achieve successful crossbreeding, it is crucial to ensure that only the intended pollen grains are used for pollination, while also protecting the stigma from any unintended contamination. This careful selection and controlled pollination process helps breeders create commercially superior varieties with specific traits.
In artificial hybridisation, flowers are covered with a bag of suitable size to prevent contamination of the stigma with unwanted pollen. The bag is generally made of:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Butter paper
After emasculation, the flower is covered with a bag of suitable size so that unwanted pollen cannot reach its stigma. This step is called bagging, and NCERT names butter paper as the material the bag is generally made of.
Option (3) Butter paper — Correct. The bag used in bagging is generally made of butter paper.
