Question

19(a).  Angiosperms and gymnosperms produce
fruit and pollen
seeds and fruit
seeds and flowers
seeds and pollen

Answer 1

Ans:-Seeds and fruit

The fruit is a characteristic feature of the flowering plants or angiosperms.The ovary matures to form fruit and the ovarian wall develops into the wall of fruit called pericarp.Fruit is a mature or ripened ovary,developed after fertilisation.The gymnosperms are plants in which the ovules are not enclosed by any ovary wall and remain exposed ,both before and after fertilisation.The seeds that develop post-fertilisation,are not covered ,seeds are naked.As seeds are produce by gymnosperms and fruit are produce by angiosperms,so correct answer is seeds and  fruit.

As gymnosperms lack ovary ,so thay can't produce fruit.As pollen is a male reproductive part ,it is not a result of fertilisation.so,option 1 that is fruit and pollen are incorrect.

flowers is the reproductive part of angiosperms,it is not a result of post fertilisation.so,seeds and flowers are incorrect.

pollen is a male reproductive part of flowering plant or angiosperms .this is not a result of fertilisation.so ,option seeds and pollen are incorrect.
