Pollination Types

Click on the flashcard to see the answer

What is pollination?

Pollination is the transfer of pollen from the male part (anther) of a flower to the female part (stigma) of the same or another flower.

What are the main types of pollination?

The main types of pollination are self-pollination and cross-pollination.

What is self-pollination?

Self-pollination is the process where pollen from the same flower or another flower on the same plant fertilizes the ovules.

What is cross-pollination?

Cross-pollination is a process where pollen is transferred from the flower of one plant to the flower of another plant.

What are biotic pollinators?

Biotic pollinators are living organisms like insects, birds, and bats that facilitate pollination by carrying pollen from one flower to another.

What are abiotic pollinators?

Abiotic pollinators refer to non-living physical factors such as wind and water that assist in the transfer of pollen.

How does wind pollination work?

Wind pollination occurs when the wind carries pollen grains from the male anthers to the female stigmas of other plants.

How do insects contribute to pollination?

Insects such as bees, butterflies, and beetles transfer pollen while they collect nectar from flowers, inadvertently aiding in pollination.

What role do birds play in pollination?

Birds, especially hummingbirds, pollinate flowers by transferring pollen while feeding on nectar using their beaks.

What is a specific example of a wind-pollinated plant?

Rye is an example of a wind-pollinated plant.

What is an example of a plant that requires biotic pollination?

Fruit trees, such as apple trees, often depend on bees and other insects for pollination.

What is one advantage of self-pollination?

Self-pollination ensures seed production even in the absence of pollinators and in unfavorable conditions.

What is a disadvantage of self-pollination?

A disadvantage of self-pollination is the limited genetic diversity it provides, which can result in vulnerability to diseases.

What makes cross-pollination beneficial for plant species?

Cross-pollination increases genetic diversity, which enhances plant adaptability and resilience to environmental changes.

How do flowers adapt to attract pollinators?

Flowers may exhibit bright colors, aromatic scents, and special shapes or nectar guides to attract specific pollinators.
