Unisexual and bisexual flower


Sexual reproduction forms a mode of replication where two parents, one male and the other female, are involved in producing a new individual. The flower itself forms the reproductive part of a plant and can be unisexual or bisexual depending on the type of flower.

Reproduction in Plants

While some plants reproduce asexually, most flowering plants reproduce sexually. Complete flowers consist of Unisexual and bisexual flower main parts, namely the petals, sepals, stamen and pistil or carpel. The stamen forms the male reproductive part and consists of two parts: The anther forms a sac which produces and stores pollen while the filament supports the anther.

The pistil on the other hand, forms the reproductive part of the flower and comprises of three parts — a stigma, style and ovary. A flower may contain either a stamen or pistil or both. Unisexual flowers are also known as incomplete flowers and contain either the male or female reproductive organs within the flower while bisexual flowers are defined as complete flowers wherein the male and female reproductive organs are contained.

These are commonly referred to as the androecium male flowers and gynoecium female flowers which is contained all in one flower.

What is the difference between...

These bisexual flowers are often referred to as being hermaphrodites or androgynous flowers as they contain both the stamen and pistils within the same flower. Pistils form the female reproductive organs of plants and flowers having only pistils are said Unisexual and bisexual flower be pistillate or female while a flower having stamens is said to be staminate or male as these form the male reproductive organs.

Main Difference – Unisexual vs...

A mature pistil contains one or more ovules, style, and a stigma while stamens contain anthers, which are held together by filaments. Unisexual flowers contain both the male flowers which hold the stamen and the female flowers which hold the pistils. In many of these unisexual flowers, the non-functioning organs of the other sex may still be present but in a reduced form and these flowers are said to be either functionally male Unisexual and bisexual flower female.

In addition, unisexual flowers consist of two types, namely monoecious and dioecious.

Unisexual vs Bisexual flowers Introduction...

Plants that contain both male and female flowers are referred to as being monoecious while plants that contain either male or female flowers are referred to as being dioecious. Bisexual flowers on the other hand contain a single flower with both the male pollen producing parts and female seed-producing parts, also known as the anthers and ovary.

Common examples of monoecious plants include corn while asparagus, dates and spinach are all common examples of dioecious plants. Unisexual plants can be broken down into two main types, namely monoecious and dioecious. Examples of monoecious plants include corn while dioecious plants include cottonwood trees, mulberry trees and holly.

Bisexual plants can further be divided into hermaphrodite or androgynous flowers and common examples include sunflowers, tulips, daffodils and mustards. Monoecious unisexual flowers undergo both self-pollination and cross pollination while dioecious unisexual flowers can only undergo cross pollination due to the presence of one type of flower. On the other hand, reproduction Unisexual and bisexual flower bisexual plants occurs via self-pollination Unisexual and bisexual flower cross pollination.

This is most likely because of both male and female reproductive organs being present within the same flower. In self-pollination, pollination of the plant stigma occurs by pollen grains of a flower that is known to be genetically identical. This in turn results in the production of offspring that are genetically identical parent flowers. Unisexual and bisexual flower can occur in various ways: Autogamy is defined as pollination within the same flower while geitonogamy is pollination that occurs within different flowers but on the same plant.
