With the help of a diagram, explain sexual reproduction in flowering plants

Reproductive organ of a sexually reproducing plant is a flower.

Flowers can be unisexual, i.e., either have a stamen (male organ) or carpel (female) or can be bisexual.

Fertilization of egg cells in ovules by pollen grains leads to the development of the embryo whereas the entire ovule gets converted into a seed.

Seeds under favorable conditions germinate to give rise to a new plant.

Hence this is the process of sexual reproduction in flowering plants
