Agent of pollination and their characteristics

There are two major types of pollination sometimes we say that they are sometimes we say that their self pollination and cross pollinatio sometimes we say that they are self pollination and cross-pollination but at this very moment we want to look at the agent of pollination and this to major agent of pollination and this two major agent of pollination are insect pollination and wind pollination


Insect are major agent of pollination and some of the insect that causes pollination in plant are butterfly bees and Moth,

an insect caused pollination is a pollination process that is carried out by insect that goes about sucking the nectar of flowers

So what are the major characteristics of insect pollination
Here are some of the characteristics of pollination caused by insect

Insect-pollinated flowers are also calle insect pollinated flowers are also called entomophilous flowers and they have the following characteristics

1. Any flower that is pollinated by insects have large conspicuous petals and sepals

2. The flowers are usually brightly coloured that usually attract insects to it

3. For a flower to be pollinated by insects it must possess nectar

4. The pollen grain of insect pollinated flowers are usually sticky and relatively few

5. The stigma of an insec the stigma of an insect-pollinated flower is flat with sticky surface to enable it receive pollen grain

6. Petals are shaped and arrange to enable insect become dusted with pollen grain durin pollination


Typical examples of insect pollinated flowers are hibiscus flower and pride of Barbados


The process of pollination by insect
The insect that normally pollinate pride of Barbados are the swallowtail butterfly and bees


When they lands on the standard petal it uncoils the proboscis and insert it into the furrow that leads into the nectar

During this process the hairy body or the wings of the butterfly rubs off on the pollen grain which are transferred to the stigma of e plant

Characeristics of wind-pollinated flowers

Wind-pollinated flowers ee also called anemophilous flowers and they have the following characteristics

1. The flowers of a wind-pollinated flower is small inconspicuous petals and sepals

2. The colours of a wind pollinated flower are always dull

3. Most flowers that are pollinated by wind don't have scent. They don't have smell
4. Large quantities of pollen grains are produced
5. Pollen grains are small, smooth, light and they are not sticky to enable wind to be able to transport them to the next flower available

6. The stigma of a wind-pollinated flower is elongated and sticky with large surface area
7. The anthers of these flowers are attached in such a way that they readily swing in the air and released the pollen grain whenever the wind is blowing

Typical examples of wind-pollinated flowers are maize, Guinea grass, rice, millet and wheat

The process of pollination by wind
the Male flower ripen before the female flowers on the same plant.

This favour cross pollination so they wind the carries it pollen grain of one maize to another plant with ripe female flowers

If the pollen grain falls on stigma if the pollen grain then cross pollinatio takes place
