Base of nucellus from which integument arises is

Megasporogenesis is defined as the process of formation of megaspores from the megaspore mother cell (MMC). MMC is a diploid cell This process occurs inside the nucellus of the developing ovule. The mass of cells enclosed within the integuments is called ..................

Nucellus is mass of cells enclosed within integuments.

Nucellus is mass of cells enclosed within integuments.

Embryosac is otherwise known as female gametophyte. The body of the ovule between the chalaza and embryo sac is called hypostase. Tenuinucellate ovules have very small nucellus. The ovule with one integument said to be monosporic.
