What Flower Part Contains Egg Cells?
Flowers or blooms contain egg cells in the female portion of the bloom called the pistil. Egg cells will create seeds to help the flower reproduce or make new plants of the same species.
Egg cells are found in the ovules which are located in the ovaries. Pollination by a plant of the same species must occur before eggs will become seeds. Often the male and female part of a flower are located in the same bloom.
For pollination to occur, pollen from the male anther must reach the female stigma where it is transported down through the style to the waiting ovary. This task is completed by the wind, visiting insects, birds or passing animals.

Other parts of the flower that do not create seeds but are necessary for seed production are the attractive colorful petals and the oils that create fragrance. Color and fragrance help attract pollinators.
Pollination can be completed by hand but is very tedious. A small object like a cotton swab can be used to gather pollen from the anther and deposit it on the stigma. This process may be used in controlled greenhouses or laboratories to impregnate egg cells where insects are not welcome guests.
Female Parts Of The Flower?
The stigma is the sticky structure that tops the pistil, the name given to the entire female structure contained in a flower. The stigma catches pollen, activating and holding it securely as it elongates and grows toward the ovary. The style is a tube that raises the stigma above the base of the flower and separates it from the ovary. Although this may seem insignificant, this distance is one way that incompatible pollen is prevented from attempting to fertilize eggs -- species whose pollen tubes don't grow long enough simply cannot reach the ovary. In addition, the stigma being raised above the base of the flower increases the odds of pollination for many plants. Pollen tubes that reach the ovary release their sperm cells directly within, fertilizing the ovules. After fertilization is complete, a chemical signal encourages the ovary to produce a protective environment where the seed develops.
