Expert Answer:

The flower of a plant contains a carpel which has the female pistil within it. At the top of the pistil is a sticky pad called the stigma. This area catches pollen either from the same flower, but more often from another flower. This happens as a result of insects hovering from flower to flower, or by wind, water, birds, small mammals and by humans. Later, when the pollen unites with the egg or the ovule within the pistil, fertilization takes place. After some time, within the seed casing, the period of germination takes place. Germination is process by which the plant embryo or the baby plant within the seed grows and the baby seedling comes forth from the seed. Optimum temperature, humidity and effect of plant hormones triggers the development of seeds in plants.
