Question

Apomictic seeds are formed due to

• A. Formation of egg without reduction division.
• B. Protrusion of nuclear cells into embryo sac.
• C. Development of embryos from sporophytic tissues like integumentary cells.
• D. All of the above.

Answer 1

The correct option is D All of the above.

There are several ways in which apomictic seeds are formed. In some species, diploid egg cell formed without reduction division or meiosis will develop into an embryo without fertilisation. In such cases there is no recombination of genes. Sometimes sporophytic cells like nucellar cells and integumentary cells protrude into the embryo sac and develop into embryos.
