Parts of a flower
The male part of the flower
Stamen (made of the anther and filament)
How do flowers attract insects to them?
Bright colors and scents
Where pollen is produced
Anther
This part of the stamen produces pollen.
Anther
What percent of the world's original forests have either been cleared or destroyed?
80%
the female part of the flower
Pistil (made of the stigma and style)
All flowers are pollinated by insects, true or false?
False
The structure that holds up the anther
Filament
These protect the bud before it blooms.
Sepals
How many plant species are safe to eat?
Over 80,000
This is where the pollen tube grows after pollination.
Style (long part of the pistil)
Wind-pollinated flowers produce a smell, true or false?
False
Where pollen attaches itself to the flower after leaving the anther
Stigma
This is sticky to catch pollen during pollination.
Stigma
How many plant species are used for medicine?
70,000
This is where the seed and fruit develop in a flower.
Ovary
What is the purpose of the petals?
To attract insects for pollination
How is the stigma adapted for its function?
It is very sticky
This gives support to the anther.
Filament
Name four methods of seed dispersal shown in the chapter.
Wind, water, animals, and explosion.
The part of the flower that holds a singular egg cell
Ovule
Where does fertilization take place?
In the Ovary
Where does the pollen have to travel down to get from the stigma to the ovary?
Style (the tube in the style)
This grows around the seeds to protect them until germination.
Fruit
Explain how a flower can develop into a fruit containing seeds.
After pollination, a pollen tube grows towards the ovary. Fertilisation occurs when the pollen joins with the egg. The ovules develop into seeds and the ovary develops into a fruit.
