a) Transfer of pollen grains.

b) Embryo development.

c) Formation of flower.

d) Formation of pollen grains.

e) Formation of an endosperm.

f) Fruit development.

b, e, f.

Post fertilisation is defined as a series of events that occur in order for the plants to produce a fruit. After fertilisation, a series of events occur in the development of plants to form a fruit from a diploid zygote. The four different developmental steps that occur during post fertilisation are described below:

• The Formation of an endosperm.
• The Growth of an embryo.
• The Growth of a seed.
• Fruit development.

Formation of flowers, formation of pollen grains and transfer of pollen grains are pre fertilisation events.
