Definition of Pollination

Pollination is a vital part of plant reproduction; the definition of pollination tells us that it is the transfer of pollen grains usually from the stamen and flower parts to the ovules. In plants like cycads, the ovules are exposed so the pollen is easily caught in a fluid that is secreted by the ovule. Whereas, in flowering plants, the ovules are usually contained in a hollow organ which is known as the pistil. 

The pollen is then deposited on its receptive surface which is known as the stigma. With time the pollen germinates and makes a pollen tube. For fertilisation one of the two sperm cells (which are within the pollen tube), fuses with an egg cell, which leads to the growth of the embryo. Further, the other cells combine with the secondary sexual nuclei of the ovule. Hence, it causes the birth of a seed. 

As a requirement, fertilisation is very important for the production of the fruit and seed. By the definition of pollination, we also get to know that fertilisation is very important as it plays a vital role in improving plants by breeding. We should also note that the study of pollination is very important as it is connected to the information about the evolution of flowers and plants in general and their distribution.

Definition of managed pollination

Do you know the definition of managed pollination? It is the horticulture practices that can increase the quality of the crops by understanding the needs of the pollination process of the specific plant.

Types of pollination 

There are usually two types of pollination, self-pollination, and cross-pollination, but to understand these you must understand the definition of pollination. The types of pollination are:

Self-pollination- In self-pollination, the anther of a flower is transferred to the stigma of the flower which might be the same or different. This will cause the birth of a new seed over some time. The pollen can directly transfer from the anther to the stigma or there might be pollinators like insects, wind, water, etc. 

Cross-pollination- Cross-pollination is the process of transferring the pollen of a flower from the anther of a plant to the stigma of another plant but of the same species, it causes the birth of a new seed over some time. The pollen can be transferred if the pollen is moved by any insect, wind, or water, and taken to the stigma of the other plant. The main thing is that there might be some trees of the same species close to each other. If the trees/plants are far apart then the transfer of pollen is almost impossible.

What is pollination?

Do you know what pollination is? Pollination is the transfer of pollen grains usually from the stamen and flower parts to the ovules. In plants like cycads, the ovules are exposed so the pollen is easily caught in a fluid that is secreted by the ovule.

What are pollinators 

Pollinators are usually animals who carry the pollen from a male anther of a plant to a female stigma of another plant or the same plant for fertilisation. Although bats, birds, and many other creatures also help in pollinating the animals listed below are the ones that do the bulk of the job. Here in the article, we will provide details of 4 insects which would also include their lifecycle, habitats, etc. 

 There are many insects mentioned below that are decreasing at an alarming rate in the world and can be extinct in some decades. 

Types of pollinators

The different types of pollinators are as follows:

Solitary bees- Honey bees are the most common and well-known pollinators but they are not the complete representation of the bee species throughout the earth at the current time, a fact to be noted is that there are more than 20,000 species all over the earth (which is a lot) Out of the whole myriad species of bees over 90% of them are solitary bees, hence they lead a solitary life instead of a social life. Most of the solitary bees are stingless and yet most of the world population still fears them. Bees are one of the most important pollinators as they have special hair and specialised anatomical structures which can help to transfer pollen from one plant to another. 

Bumblebees- Bumblebees are believed to be the most important pollinator of wild plants and crops. They can carry and transport pollen in very low temperatures as well as in low light which makes them excellent pollinators.

Butterflies and moths- Butterflies and moths are both very important in the pollination of plants. But the sad news is that both of them are on their way to being instinctive from the USA. They used to inhabit the Rocky Mountains of the east and the west. 

Conclusion

Pollination is a vital part of plant reproduction; the definition of pollination tells us that it is the transfer of pollen grains usually from the stamen and flower parts to the ovules. In plants like cycads, the ovules are exposed so the pollen is easily caught in a fluid that is secreted by the ovule. 

There are usually two types of pollination which are, self-pollination, and cross-pollination, in self-pollination, the anther of a flower is transferred to the stigma of a flower which may be the same or different. Cross-pollination is the process of transferring the pollen of a flower from the anther of a plant to the stigma of another plant but of the same species. Pollinators are usually animals who carry the pollen from a male anther of a plant to a female stigma of another plant or the same plant for fertilisation. Some types of pollinators are bees, moths, butterflies, etc.
