Ovule vs. Seed

Main Difference

The main difference between Ovule and seed is that ovule is a female gametophyte that after fertilization transforms into seed where the seed is an embryonic plant which is encapsulated in a covering.

Ovule vs. Seed

The ovule is the part of the pistil in a plant and hence located in flower means in the ovary. A seed, on the other hand, is present in fully repined fruit. After fertilization, the ovary develops to form fruit, and the ovule becomes a seed. Outer covering in both ovule and seed protects against microorganisms and mechanical damage. In ovule, the outer cover is called integument. It protects the nuclear tissue of the ovule. Whereas in the case of seed, the outer covering is called testa which is harder and provides protection to the delicate inner structures of a seed? The helium is a small point present on the surface of both ovule and seed. In ovule, helium is the point at which the body of the ovule is attached to the funiculus. In contrast, in seed, helium is the point at which the seed attaches itself to the fruit. Helium on the seed can be identifying as a black scar.

Cotyledon is a seed leaf which is essential for the food collection. In ovule, the parenchymatous cells (nucellus) store food which is used by the embryo sac for its development. In the case of seed, cotyledon plays the role of providing food for the seed as cotyledon is highly packed with starch. The micropile is a small opening on the surface of ovule and seed. In ovule, micropile provides an entrance for the pollen into ovule to carry out the process of fertilization. While in seed, micropile provides entry for water which is essential for its germination.

What is Ovule?

The ovule is a part of the female reproductive organ in seed plants. It is the place where female sexual cells are made and located and after it develops into a seed after fertilization and the seed forms a complete plant. Ovules are located in ovaries at the bottom of the vase-like part, the carpel, which has a neck called style and an opening called stigma. After fertilization, ovule starts to swell, and its wall starts to get tough to prepare a seed, and its walls begin to grow around it and become the fruit. Some plants like avocado have a single ovule in ovary while in some plants; there are many ovaries which develop into many seeds. Another aspect that plants differ from each other regarding the ovule is the place where the ovules are present. In gymnosperms, ovules are found on the scales of female cones while in angiosperm, ovules are present inside the ovary within the carpel.

The ovule plays a vital function in sexual production. Once pollen falls on the stigma of a flower, it sends a pollen tube down through the style. This tube enters into the ovary and reaches the ovule of the plant. Once this process starts, fertilization arises as the nucleus of the pollen is sent down into the tube to merge with the nucleus in the embryo sac. Components of an ovule are the nucellus, integument, the female gametophyte. Ovules have classified into six categories based on shapes; orthotropous, anatropous, Hemi anatropous, campylotropous, amphitropous and cirinotropous,

What is Seed?

The seed is an essential part of any plant. The ovule after fertilization forms seed. The embryo is made up of a radicle, embryonal axis, and one or two cotyledons. Seeds are found in fruits and can be converted into new plants when planted. A seed is of two types; monocotyledonous seed and dicotyledonous seed. As the name is depicting, a monocotyledonous seed has only one cotyledon. There is only one covering of the seed coat. The monocotyledonous seed has the following parts; seed coat, endosperm, aleurone layer, embryo, scutellum, embryonic axis, and coleoptile. Unlike monocotyledonous, the dicotyledonous seed has the following elements; seed coat, helium, microphone, embryo, cotyledon, radicle, and endosperm. Seeds are produced in various related groups of plants and manner if different from angiosperms from the gymnosperm. In angiosperms, seeds are enclosed in fruits whereas, in gymnosperm, seeds are naked.

Conclusion

It has concluded from the above discussion that both ovule and seed are part of a fruit. After full development, ovule becomes a seed.
