What is pollination?
Click to flip
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.
Click to flip
What are the main types of pollination?
Click to flip
The main types of pollination are self-pollination and cross-pollination.
Click to flip
What is self-pollination?
Click to flip
Self-pollination is the process where pollen from the same flower or another flower on the same plant fertilizes the ovules.
Click to flip
What is cross-pollination?
Click to flip
Cross-pollination is a process where pollen is transferred from the flower of one plant to the flower of another plant.
Click to flip
What are biotic pollinators?
Click to flip
Biotic pollinators are living organisms like insects, birds, and bats that facilitate pollination by carrying pollen from one flower to another.
Click to flip
What are abiotic pollinators?
Click to flip
Abiotic pollinators refer to non-living physical factors such as wind and water that assist in the transfer of pollen.
Click to flip
How does wind pollination work?
Click to flip
Wind pollination occurs when the wind carries pollen grains from the male anthers to the female stigmas of other plants.
Click to flip
How do insects contribute to pollination?
Click to flip
Insects such as bees, butterflies, and beetles transfer pollen while they collect nectar from flowers, inadvertently aiding in pollination.
Click to flip
What role do birds play in pollination?
Click to flip
Birds, especially hummingbirds, pollinate flowers by transferring pollen while feeding on nectar using their beaks.
Click to flip
What is a specific example of a wind-pollinated plant?
Click to flip
Rye is an example of a wind-pollinated plant.
Click to flip
What is an example of a plant that requires biotic pollination?
Click to flip
Fruit trees, such as apple trees, often depend on bees and other insects for pollination.
Click to flip
What is one advantage of self-pollination?
Click to flip
Self-pollination ensures seed production even in the absence of pollinators and in unfavorable conditions.
Click to flip
What is a disadvantage of self-pollination?
Click to flip
A disadvantage of self-pollination is the limited genetic diversity it provides, which can result in vulnerability to diseases.
Click to flip
What makes cross-pollination beneficial for plant species?
Click to flip
Cross-pollination increases genetic diversity, which enhances plant adaptability and resilience to environmental changes.
Click to flip
How do flowers adapt to attract pollinators?
Click to flip
Flowers may exhibit bright colors, aromatic scents, and special shapes or nectar guides to attract specific pollinators.
