What is a mature ovule called?

A mature ovule consists of a food tissue covered by one or two future seed coats, known as integuments. Each ovule is attached by its base to the stalk (funiculus) that bears it. … After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo.

What is the main function of the ovule in a flower?

The ovule is the organ that forms the seeds of flowering plants. It is borne in the ovary of the flower and consists of nucellus protected by integuments, precursors of embryo/endosperm, and seed coat, respectively.

Oocyte: the cell in animals that develops into an egg. Once it is fertilizable, it is referred to as an egg. Ovule: the structure in seed plants that develops into a seed after fertilization. It consists of one or two integuments forming its outer layers, the nucellus and the female gametophyte.

How Nucellus is formed?

NUCELLUS TYPE An immature ovule contains a single large cell known as an archesporial cell. In some taxa the archesporial cell undergoes a single periclinal division, resulting in the formation of an outer parietal cell and an inner megasporocyte (Figure 11.8).

What is inside the ovule?

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.
