it is called a filly
In plants, immature egg cells are held within structures called ovules, which are found inside the ovary of the flower. Each ovule contains a megasporangium where the immature egg cell, or megaspore, develops. The ovule is surrounded by protective layers and is attached to the ovary wall, ensuring the egg cell is nurtured until it is ready for fertilization.
No, an immature female ovary cannot be fertilized. Fertilization requires a mature ovum (egg), which is typically released during ovulation. Immature follicles do not contain viable eggs capable of being fertilized. Only mature eggs, once they have completed their development, can be fertilized by sperm.
The round structures in the ovary that you see under the microscope are called ovarian follicles. These follicles contain developing eggs and are the basic functional unit of the ovary. Each follicle consists of an oocyte (immature egg cell) surrounded by different layers of cells.
The ovary is the ovary before it is fertilizes (containing the ovules); after fertilization the ovary becomes the fruit and the ovules become the seeds
An immature butterfly is called a caterpillar.
An immature or baby eagle is called an eaglet.
The ovary does not contain embryos - or if it does it is a medical emergency! The ovary is the site where immature eggs are stored and released. Fertilization of the egg to form embryos occurs outside the ovary, typically in the fallopian tube. Most of embryonic development occurs post implantation in the uterus. The ovary should never contain an embryo.
An immature sow
An immature female sheep is called a ewe lamb. An immature male sheep is called a ram lamb.
The background substance of the ovary is called the stroma. The name for the expulsion of the secondary oocyte from the ovary is called ovulation.
An immature female duck is called a duckling. Once the female duck matures it is called a hen or duck.
The immature form of an animal such as a tadpole is called larva.
