When the anthers and stigma of a flower mature at the same time, this is known as homogamy. Self-pollination causes the plant to achieve homozygozity, allowing a particular gene to be obtained from each of the parents, resulting in the possession of two identical versions of that gene.

Herkogamy (or hercogamy) is a typical hermaphroditic angiosperm technique for reducing sexual interference between male (anthers) and female (stigma) function. Herkogamy differs from other similar methods (such as dichogamy) in that the anthers and stigma are separated spatially.

In a flower, dicliny refers to the existence of only one kind of reproductive whorl. As a result, dicliny is referred to as unisexuality. A plant can be monoecious (both male and female flowers are borne on the same plant) or dioecious (male and female flowers are borne on separate plants) in dicliny.

Perisperm is a permanent remnant of the nucellus. In certain seeds, it encloses the embryo and provides nourishment for it. In an angiosperm seed, it covers, stores food, and provides nourishment to the embryo. It is a diploid species.

A modified cotyledon, or seed leaf, is assumed to be the scutellum. This seed leaf never develops into a green structure in grasses, and its sole purpose is to digest endosperm and deliver nutrients to the rest of the embryo. It functions to absorb nutrients from the endosperm during germination and is relatively thin with a large surface area.
