Question

One of the essential organs for fertilisation is

• A. Mature ovule
• B. Green sepals
• C. Coloured petals
• D. Juicy fruit

Answer 1

The correct option is A Mature ovule

Ovule is the plant structure containing the embryo sac. It is the basis of female reproductive structure that further develops into a seed after fertilization. It consists of a megasporangium surrounded by one or two layers of tissue called integuments. The megasporangium produces spores that develop into megagametophyte. The megagametophyte produce one or more egg cells. Pollen grains enter the ovule through an opening called micropyle and fertilize the egg cells. The resulting embryo develops within the ovule and becomes a seed.

So, the correct answer is option A.
