The reproductive organs are the Stamens and Carpels. Plants must be pollinated to produce seeds. In angiosperms, pollination is the transfer of pollen from the anther of the stamen (the male structure) to the stigma of the carpel (the female structure). The flowers may be self-pollinated or fertilized. Fertilization is a process in which pollen is transferred from one flower to another.
The pollen can come from a variety of sources, such as insects, birds, and other animals, or it can be produced by a plant itself. Some plants produce their own pollen, while others rely on insects to pollinate them. Pollen is produced in a number of different ways, but the most common method is to deposit pollen on the surface of a flower.
This process is called seed dispersal. When a seed is deposited on a surface, the seed germinates and begins to grow into a new plant. Seeds can also be dispersed by wind or water.

How does flower shape affect pollination?
Flower shape and size provides visual clues and a structure that allows a specific, co-evolved pollinator to contact the flower’s anthers and stigmas. Since beetles are not as fast in flight as birds, pollinated flowers tend to have larger and more open flowers that provide an easy landing pad. Bumblebees and wasps are the only insects known to pollinate flowers.
Bumblebee pollination is accomplished by the use of a sticky substance called honeydew, which is released into the air when a bee lands on a flower. Wasps, on the other hand, use a chemical called pheromone to attract bees to their nests. Bees are attracted to the scent of the wasp’s scent, and the bees then fly to a nearby flower to lay their eggs.
What are the structures involved in pollination?
The pistil is made up of three parts, the ovary, the style and the stigma. Once pollination takes place, the ovary develops into a fruit by holding the unfertilized seed. The stigma is the uppermost section of the pistil, and is used to protect the seed from the wind and rain.
How does the structure of the pistil help with pollination?
The structure of a stigma aids in pollination because the stigma is designed to trap pollen and funnel it down the style (a long tube) to the ovary. Most stigma have small appendages such as hairs or flaps that are designed to catch pollen when a bee lands on the flower or when the wind blows it. Stigma can also be used to attract pollinators.
For example, if a plant is covered with a thick layer of stigmas, bees will not be attracted to it. However, when bees land on a stigmatic plant, the pollen will be trapped in the stigmata, and the plant will attract more bees. Stigmatic plants are also more attractive to bees because they are more likely to be pollinated by bees that have been trained to visit them.
Do the design and architecture of a flower play a role in pollination?
The shape of the flower will determine what type of insects may or may not gain access to the flowers, and colour and scent are the main forms of advertisement flowers use to attract a pollinator. Flower shape and colour can also be used as a means of attracting pollinators.
For example, a flower with a round shape may attract bees, while a square shape will attract butterflies and moths. The colour of flowers also plays an important role in attracting bees and butterflies, as well as other insects, such as wasps and beetles.
Which part of the flower attracts pollinators?
The petals of a flower give it its unique shape, color and smell. Their job is to get insects and hummingbirds to pollinate the flower. The pollinator’s job is to collect pollen from the flowers and deliver it to the bee.
How does shape and structure of flower influence pollination in plants?
The flowers have different shapes, colors and smells to attract certain animals. The shape of a flower will make pollination by a particular insect easier or more attractive and in return the pollinator will be more likely to lay its eggs on the flower.
Pollination is the process by which insects lay their eggs in the flowers of plants. Pollinators are insects that feed on nectar and pollen from flowers. They include bees, wasps, butterflies, beetles, grasshoppers, moths, flies and beetles.
