Answer 1

The correct option is A A- 2, B- 1, C- 4, D- 3

Intine - cellulose
Pollen - microspore mother cell
Pin-eyed - Long styled
Thrum-eyed - Short styled
The pollen grain has an inner and outer layer. The inner layer is called as intine and the outer one is called as exine. Intine is composed of cellulose.
A diploid cell in plants that divides by meiosis to give rise to four haploid microspores. In flowering plants microspore mother cells are formed within the pollen sacs of the anthers by mitosis; the microspores they produce develop into pollen grains.
Pin-eyed : Having the stigma in the mouth of the corolla, on one end of a long style with the stamens lower in the tube
Thrum-eyed: Having on a short style below the anthers, which like in the mouth of the corolla on big stamens.
