Explanation:
obary
- One of the two parts of the female body that produce eggs.
- The female gonad, one of a pair of reproductive glands in women.
- The ovaries are located in the pelvis, one on each side of the uterus.
- Each ovary is about the size and shape of an almond. The ovaries produce eggs (ova) and female hormones.
- During each monthly menstrual cycle, an egg is released from one ovary. The egg travels from the ovary through a fallopian tube to the uterus.
- The ovaries are the main source of female hormones, which control the development of female body characteristics, such as the breasts, body shape, and body hair.
- They also regulate the menstrual cycle and pregnancy.
ovule
- Ovule, plant structure that develops into a seed when fertilized.
- A mature ovule consists of a food tissue covered by one or two future seed coats, known as integuments.
- A small opening (the micropyle) in the integuments permits the pollen tube to enter and discharge its sperm nuclei into the embryo sac, a large oval cell in which fertilization and development occur.
- Each ovule is attached by its base to the stalk (funiculus) that bears it.
ovum
- The female reproductive cell or gamete of animals, which is capable of developing, usually only after fertilization, into a new individual.
- The female reproductive cell or gamete of plants.
- All sexually reproducing organisms make sex cells called gametes. The gamete, produced by the female is called the egg or ovum (plural = ova).
- It joins with the sperm, the male gamete, during fertilization to form the embryo, which will eventually grow into a new organism.
- Ova are produced by sexually reproducing animals, protists, fungi and flowering plants and ferns.
- In animals, they are produced by follicle cells in the ovaries of the female. In plants, egg cells are produced by ovules found inside the ovary (the part which then becomes the fruit).
