Pollination Flashcards
Flower Structures
Flowers have several organs that provide protection or support, or are involved in the reproductive process.
There are basically four structures – Sepals, petals, stamen, and pistils.
Petal
The petal is the colored part of the flower that gives it a unique shape.
Petals are often brightly colored to attract insects, birds, bees, and other animals. In this way, the petals aid with the pollination of the plant.
Sepal
These are leaf-like structures attached to the outside of the flower. They’re very similar to petals but with the function of enclosing the developing bud. Some sepals are green while others look similar to the flower’s petals.
Stamen
The stamen is the male reproductive part of a flower. It produces pollen and consists of a filament and an anther.
Anther: This sac-like structure is located at the tip of the filament and is the site of pollen production.
Filament: A filament is a long stalk that connects to and holds up the anther.
Carpel/Pistils
The female reproductive part of a flower is the carpel. It consists of the stigma, style, and ovary.
Stigma: The tip of the carpel is the stigma. It is sticky so it can collect pollen.
Style: This slender, neck-like portion of the carpel provides a pathway for sperm to the ovary.
Ovary: The ovary is located at the base of the carpel and houses the ovules.
What do flowers depend on to pollinate?
To pollinate flowers depend on wind and animals.
Humming birds, bats, lizards, bees, moths, butterflies and many other insects are attracted to?
The animals are attracted to the color of the flower’s petal and act as pollinators.
What are these pollinators usually collecting?
These pollinators usually collecting nectar which is a sweet liquid produced at the base of the flower. Some are collecting the pollen for food.
How is pollen transported to a new flower?
Pollen transported to a new flower when the pollen sticks to the animals’ bodies.
What happens after pollination?
After pollination the petals fall away.
Describe the pollination process.
Pollen from the male (STAMEN) parts of the flower is shaken or carried down the PISTIL into the flower’s OVARY.
Where are seeds found?
Seeds are found inside flowers and fruits.
Where are seeds found?
Seeds are found inside flowers and fruits.
What is a flower’s function?
A flower’s function is to make seeds to reproduce the plant.
What is the seed’s function?
The seed’s function is to survive and grow into a new plant.
