OVULUM Meaning and
Definition
-
Ovulum is a technical term used in biology to describe a small structure found in plants. More specifically, it refers to the initial stage of development of an ovule. An ovule, in turn, is considered to be the fundamental reproductive unit of seed plants (angiosperms and gymnosperms). It is the structure from which the potential seed and fruit arise.
The ovulum is situated within the ovary of a flower and represents the female reproductive part of the plant. It contains the female gamete, or egg, which is necessary for fertilization and subsequent seed formation. The ovulum itself is composed of various components, including the embryo sac, integuments, and micropyle. The embryo sac nurtures the developing egg, while the integuments function as protective coverings for the ovulum. The micropyle is a small opening through which the pollen tube enters during fertilization.
As the ovulum matures, it undergoes complex changes, including the development of the female gametophyte. This process eventually leads to the formation of the ovule, which then has the potential to be fertilized by pollen and develop into a seed. Overall, ovulum is a crucial precursor to seed formation and plays a vital role in the reproduction and propagation of many plants.
