What part of the flower receives pollen?

The stigma is the sticky tip of the pistil, the female part of the flower.
What is the function of the ovary in a flower?

The ovary is part of the pistil and contains ovules.
What are the male reproductive parts of a flower called?
Stamens
Stamens consist of the anther and filament.
Fill in the blank: The _______ is where the seeds grow.

What is pollination?
The transfer of pollen for reproduction in plants
Pollination enables fertilization and the production of fruit and seeds.
True or False: Only 10% of flowering plants are pollinated without animal assistance.
True
What is cross-pollination?
Transfer of pollen from one plant to the stigma of another plant
Cross-pollination promotes genetic diversity.
What is self-pollination?
Fertilization by transfer of pollen within the same flower or between flowers on the same plant
Self-pollination does not exchange genetic material.
List some agents of pollination.
- Insects
- Birds
- Bats
- Wind
- Water
What percentage of global food production depends on insect pollination?
35%

What is the relationship between pollination and vegetables?
Pollination may be required for fruit production and seed production
Examples include tomatoes and cucumbers.
What can be done to help honeybee populations?
- Plant honeybee-friendly plants
- Avoid using chemicals to kill pollinators

True or False: Pollination is not required for the production of storage roots like carrots.
True
What is the ecological value of pollination?
Valuable part of ecology
Pollination supports biodiversity and ecosystem health.
What is biotic pollination?
Pollination by living organisms, primarily insects
Other pollinators include birds and bats.
