endosperm culture

Endosperm culture: It is the in vitro development of isolated mature or immature endosperm from seed at proper stage on a suitable culture medium to obtain triploid plantlet.

What is the function of the endosperm?

The endosperm plays an important role in supporting embryonic growth by supplying nutrients, protecting the embryo and controlling embryo growth by acting as a mechanical barrier during seed development and germination.

What is endosperm in simple words?

Endosperm is a food reserve tissue inside the seeds of most flowering plants. It surrounds the embryo and provides nutrition in the form of starch. It may also contain oils and protein. The endosperm of cereal plants is an important source of nutrition for humans. Wheat endosperm is ground into flour for bread.

Which foods are examples of endosperm?

For example, wheat endosperm is ground into flour for bread (the rest of the grain is included as well in whole wheat flour), while barley endosperm is the main source for beer production. Other examples of endosperm that forms the bulk of the edible portion are coconut "meat" and coconut "water", and corn.

What is ovule culture?

Ovule culture is an elegant experimental system by which ovules are aseptically isolated from the ovary and are grown aseptically on chemically defined nutrient medium under controlled conditions.

What are the three types of endosperm?

The primary endosperm nucleus divides rapidly to form the endosperm tissue. The endosperm nuclei increase in size as the development proceeds. In angiosperms there are three types of endosperm development— namely, nuclear, cellular, and helobial.

What is endosperm and its types?

In angiosperms the endosperm is a special tissue which is formed as a result of vegetative fertilization, triple fusion or fusion of a male gamete with diploid secondary nucleus of the central cell. ... Depending upon the mode of its formation, angiospermic endosperm is of three types— nuclear, cellular and helobial.

What are the two types of endosperm?

ADVERTISEMENTS: Three main types of endosperm development in flowering plants are: (i) Nuclear type (ii) Cellular type and (iii) Helobial type! The formation of endosperm is initiated by mitotic divisions of the primary endosperm nucleus (3N). The formation of endosperm occurs usually prior to the zygotic division.

How is endosperm formed?

Endosperm is formed when the two sperm nuclei inside a pollen grain reach the interior of a female gametophyte (sometimes called the embryo sac). ... That cell created in the process of double fertilization develops into the endosperm.

What does cotyledon mean?

Cotyledon, seed leaf within the embryo of a seed. ... Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.

In which fruit can one find Polyembryony?

Ans. Polyembryony is common in citrus plants as well as mango and jamun where multiple embryos arise from sporophytic cells of ovules or zygote.

What is inside a seed?

Seeds have a seed coat which protects them while they grow and develop, usually underground. Inside the seed there are is an embryo (the baby plant) and cotyledons. When the seed begins to grow, one part of the embryo becomes the plant while the other part becomes the root of the plant.

What is a Plumule?

1 : the primary bud of a plant embryo usually situated at the apex of the hypocotyl and consisting of leaves and an epicotyl. 2 : a down feather.
