what is pollination and the different types of pollination
Definition of pollination Pollinatio is defined as the transfer of mature pollen grains from the Anther of one flower to the mature stigma of the same flower or another flower of the same plant or closely related species
Pollination is the first step which leads to the eventual coming together of the male and female gamete for the sake of fertilization in plant
List types of pollination in plants
So what are the two types of pollination
There are two major types of pollination in plant there are two major types of pollination in plant and these are saf there are two major types of pollination in plant and these are self pollination and cros there are two major types of pollination in plant and these are self pollination and cross pollination
What is self pollination
Definition of self pollination
Self pollination is the transfer of mature pollen grain from another plant.
self pollination is the transfer of mature pollen grain from the anther of a flower to the stigma of the same flower or to that of another flower of the same plant. Examples of self pollination occur in pea, tomato and cotton.
Insect pollination only one parent plant is involved. Which means during self pollination the stigma and the answer that will be used in the pollination of the flower are all under one plant so it is not that the pollen grain will be brought from another plant standing somewhere to fertilize the other plant of the same species in the place but the pollen grain of a particular tree that will be used for that same tree is called self pollination.
it is not that the pollen grain will be brought from another plant standing somewhere to fertilize another plant of the same species in the place but the pollen grain of a particular tree that will be used for that same tree is called self-pollination
What is cross pollination
definition of cross pollination
Cross pollination simply means the transfer of pollen grain from the Anther of another flower to the stigma of a flower on another plant of the same species or closely related species of plant
Examples of plant where cross pollination examples of plant where cross pollination takes place
1. Hibiscus flower exhibits cross pollination
2. Pride of Barbados
For cross pollination to take place two parent plants are involved
List the various agents of pollination
First what are agent of pollination
Agent of pollination also call pollinators are organisms or other means by which pollen grains are transferred from the anther to the stigma of flowers
Common agent of pollination are as follows
1. Insect wind, snail, birds, bats and man
Some common insect which are involved in formulation process are butterfly, moth and bees
What are the advantages of self pollination
1. One of the advantages of self pollination in plant is that it is a sure way of ensuring pollination takes place especially in bisexual flowers
2. One of the advantages of self pollination is that it may not waste pollen grains
Disadvantages of self pollination
1. Self pollination may lead to the production of weak offspring as a result of continuous and repeated self pollination
2. The Offspring or individuals produced during self pollination are less adapted to the environment
The advantages of cross pollination
1 Cross pollination leads to the production of hair the Offspring
2. another very important advantage of cross pollination is that it produces viable seeds for planting and consumption
3. The Offspring or individuals produced during cross-pollination are more adapted to the environmental conditions
4. It also lead to the formation of new varieties with good characteristics
Major disadvantages of cross pollination in plants
1. Cross pollination relies on external agent such as wind and insect whose presence at the right time cannot be guaguaranteed
2. one major disadvantage of cross-pollination is that it leads to which stage of pollen grain especially pollination by wind
What are the major differences between cross pollination and self pollination
Here are a few examples of the characteristics difference of self pollination and cross pollination
1. Self pollination takes place only in bisexual plan self pollination takes place only in bisexual plants while self pollination takes place only in bisexual plant while cross pollination takes place both in bisexual and unisexual plants
2. Insect pollination only one parent is involved but in Cross pollinatio insect pollination only one parent is involved but in cross-pollination to parents are involved in the pollination process
3. Insect pollination may occur without an external agent while cross-pollination requires external agent like insect and wind for it to take place
4. self pollination does not result in new varieties of crops or plant but cross-pollination eventually may result in the formation of new varieties soresistantare disease resistant
5. pollen grain are effectively utilised in self pollination but much of the pollen grain are wasted during cross pollination process
