Sexual Reproduction In Plants (biology) Flashcards
Male reproductive part
Stamen
Female reproductive part
Carpel
Parts in the male reproductive part
Anther
Filament
Anther
Contains pollen grains
Where are the male gametes produced?
In pollen grains
Filament
Stalk that supports the anther
What does the female reproductive part consist of?
Stigma
Style
Ovary
Stigma
The end bit that the pollen grains attach to
Style
The rod like section that supports the stigma
Ovary
Contains the female gametes inside ovules
Pollination
The transfer of pollen from an anther to a stigma, so that the male gametes can fertilise the female gametes in sexual reproduction
Cross-pollination
A type of sexual reproduction where pollen is transferred from the anther of one plant to the stigma of another
How are plants adapted for insect pollination?
Brightly coloured petals
Scented flowers and nectaries
Big, sticky pollen grains
Sticky stigma
How are plants adapted for wind pollination?
Small, dull petals
No nectaries or strong scents
Lots of pollen grains (they are small and light)
Long filaments that hang outside the flower
Light and feathery stigma
Where does the pollen grain land during fertilisation?
On the stigma of the flower
