Cross Pollination: Agents, Types, Advantages and Importance

Cross Pollination

Cross Pollination is the process of transfer of pollen grains from the anther of one flower to the stigma of another flower (on a different individual of the same species).

  • In easy words, Cross Pollination is  Pollination that occurs between two flowers of two different plants but of the same kind.
  • Cross-pollination occurs between two different plants (of the same kind).
Some examples of cross-pollinating plants are –
  • Pumpkin
  • grapes
  • Melon
  • apple
  • Squash
  • maple tree
  • Cucumber
  • daffodils

Cross Pollination is always dependent on the pollination agent for the transfer of pollens.

The pollination agents include birds, water, animals, wind, and insects.

Cross-Pollinating

Cross-Pollinating plants or flowers are those in which the pollen grains are transferred from the anther of one flower to the stigma of another flower (on a different individual of the same species).

Such Flowers are called Cross-Pollinating Flowers.

Cross Pollination Biology

Cross Pollination refers to the method of fertilization where the sperm from the pollen (from the anther) of a plant is transferred to the stigma of the flower of another plant.

In cross-pollination, new genotypes are produced more than in self-pollination because male and female gametes are from two different plants or flowers which increases the chances of production of new genotypes.

Cross Pollination helps increase genetic diversity.

Based on the agent of pollination, cross-pollination can be of the following types:

Types of Cross Pollination

types of cross pollination

1. Hydrophilous Flowers

  • These flowers are pollinated with the help of water.
  • So water in these flowers is the pollination agent.

2. Zoophilous flowers

  • In this type, the pollinating agents are animals like human beings, bats, bees, birds, etc.
  • The zoophilous flowers contain pollen that sticks to the body of the animals so that they can be easily carried from one flower to another.

3. Entomophilic flowers

  • Entomophilic flowers are pollinated by insects.
  • These Entomophilic flowers
  • have bright and colorful petals.
  • These flowers have a nice fragrance which makes them very attractive.
  • Many of these flowers secrete nectar and other sticky things that attract butterflies, bees, and birds to flowers.
  • So when insects come near flowers the pollens stick to the body of insects.

4. Anemophilous flowers

  • These flowers are pollinated by wind.
  • So wind is the pollinating agent in anemophilous flowers.

5. Ornithophilous flowers

  • These types of flowers are pollinated by birds.
  • So birds are the pollinating agents in ornithophilous flowers.

What are Cross-Pollination and Examples?

Cross-Pollination is the process of transfer of pollen grains from the anther of one flower to the stigma of another flower (on a different individual of the same species). In easy words, Cross-Pollination is  Pollination that occurs between two flowers of two different plants but of the same kind. Example – When bees, insect, and bird takes pollen from one plant and transfer it to another plant.

What is Cross-Pollination and Self Pollination?

Cross-Pollination refers to the method of fertilization where the sperm from the pollen (from the anther) of a plant is transferred to the stigma of the flower of another plant. In easy words, Cross-Pollination is pollination that occurs between two flowers of two different plants but of the same kind.

Self Pollination happens when the pollen from the anther is moved/saved to the stigma of a similar blossom or another flower on a similar plant. Self Pollination happens on just one plant. Just one single plant is engaged with Self Pollination.

Advantages of Cross Pollination

  • The newly produced offspring are mostly healthier.
  • The seeds developed when germinated under favorable conditions grow into healthier plants.
  • Cross pollination always results in new varieties of plants.
  • The seed produces are viable and are produced in large numbers.
  • Cross Pollination always results in new varieties of plants because Cross Pollination takes place between two different plants of the same species.

Disadvantages of Cross Pollination

  • Cross Pollination is always dependent on Pollination agents which include birds, water, animals, wind, and insects.
  • The Pollinating agents will not always be available for pollination.
  • More wastage of pollen grains takes place in cross pollination.
  • Distance between two plants becomes a barrier for pollination to take place.
  • A large number of Pollen Grains have to be produced by flowers to increase the chances of pollination between two plants.

What are the limitations of Cross-Pollination?

1. Cross-Pollination is always dependent on Pollination agents which include birds, water, animals, wind, and insects.

2. The Pollinating agents will not always be available for pollination.

3. A large number of Pollen Grains have to be produced by flowers to increase the chances of pollination between two plants.

4. The large distance between two different plants of the same species between which cross-pollination has to take place is the limiting factor that reduces the possibility of pollination. 

Importance of Cross-Pollination

Cross-Pollination is the process of transfer of pollen grains from the anther of one flower to the stigma of another flower (on a different individual of the same species).

Cross-pollination is important because

1. Seeds produced are in large numbers and viable.

2. The only method for the unisexual plants to reproduce.

3. The newly produced offsprings are healthier.

4. Cross-Pollination always results in new varieties which are more adaptive, better, and resistant to diseases and changes in the environment.
