Detailed explanation-1: -The micropyle is a small opening that is found in the ovule, just close to the hilum and is retained in the seed after fertilisation. When soaked, seeds absorb water mainly through the micropyle. Micropyle also helps in respiration and in the exchange of gases.
Detailed explanation-2: -Micropyle is a narrow pore or passage formed by the projection of the integuments through which the pollen tube enters into ovule. Seeds contain micropyle through which water enters into the seed during germination. So, the correct answer is ‘Water’.
Detailed explanation-3: -The micropyle is the small opening present in the seeds through which water enters seeds. The micropyle is present in the ovule of the seed. It is present at the tip where the integument does not cover the nucellus in the ovule of the seed.
Detailed explanation-4: -Correct answer is 3. Micropyle. The micropyle remains as a small pore in the seed coat. This facilitates entry of O2 and water into the seed during germination.
