In gynoecium, explain pentacapillary, position of the ovary, pentalocular with exile placentation and the number of stigma in hibiscus flower

Answer 1

Pentacapillary in gynoecium refers to the presence of five carpels or pistils in the ovary of a flower. This means that the ovary is made up of five separate structures that will develop into fruit after fertilization.

The position of the ovary in hibiscus flowers is superior, which means that it is situated above the attachment of other floral parts, such as the sepals and petals. This is characteristic of many dicotyledonous plants, including hibiscus.

In pentalocular with exile placentation, the ovary is divided into five locules or compartments, each containing ovules that will develop into seeds upon fertilization. The placentation is said to be exile because the ovules are attached to the walls of the ovary, rather than being suspended from a central axis.

The number of stigma in a hibiscus flower is also five, corresponding to the number of carpels or pistils present in the pentacapillary gynoecium. Each stigma is located at the tip of a carpel and is the site where pollen grains will germinate and begin the process of fertilization.
