28 kwi 2017 · The ovule is part of the makeup of the female reproductive organ in seed plants. It’s the place where female reproductive cells are made and contained, and it is what eventually develops into a seed after fertilization, only for the seed to then ripen and produce a complete adult plant.
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. The ovules of angiosperms are enclosed by an ovary, while those of gymnosperms are uncovered on the scales of a cone.
In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the integument, forming its outer layer, the nucellus (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center.
The ovule is a part of a plant that is popularly known as megasporangium. It is present inside the ovary base, which extends and gives rise to the stalk-like structure called style and finally opens into the stigma.
1 wrz 2024 · An ovule is a small structure within the ovary of a plant that contains the female gamete (egg cell) and develops into a seed after fertilization.
The term ovule in animals is used for the young ovum of an animal. In vertebrates, ova are produced by female gonads (sex glands) called ovaries. A number of ova are present at birth in mammals and mature via oogenesis.
The ovary serves as the site of fertilization and subsequent development of seeds. After pollination, the ovary undergoes changes, such as the thickening of its walls, to form the fruit. The ovule, on the other hand, is responsible for the production of female gametes and their protection.
