Pollination Flashcards
What is the function of flowers/petals in pollination?
They use their colourful petals to attract insects and other pollinators
What is the function of nectary in pollination?
They produce a sugary substance called nectar to attract pollinators
What is the stamen?
The stamen is the male reproductive part of a flower, made up of the anther and filament.
What is the anther
The anther is the part of the stamen that produces and releases pollen and contains the male gametes.
What is the stigma
The sticky structure that pollen attaches to
What is the filament?
The filament is the a long , thin structure that supports the anther and positions it for pollinators to access pollen easily.
What is the ovary in pollination
The ovary is the part of the pistil that contains the ovules. After fertilization, the ovary will develop into a fruit
What are ovules in pollination
Ovules are the structures within the ovary that, after fertilization, develop into seeds. Each ovule contains a female gamete
What is the style
It is a long structure that supports the stigma and connects it to the ovule
What is pollination?
The transfer of pollen from the anther to the stigma
What is self pollination?
The transfer of pollen from the anther of a flower to the stigma of the same flower
What is cross pollination?
The transfer of pollen from the anther of a flower to the stigma of a different flower
What are some adaptations that flowers have for insect - pollination
- They have colourful petals to attract pollinators
- They have a structure knows as a nectary that creates a sugary substance which attracts pollinators
- The pollen produced by anther is sticky causing it to stick on the body of a pollinator
- The stigma is a sticky structure allowing for the pollen on the pollinator to easily stick on the anther allowing for reproduction
How does mutualism happen in pollination
The flowering plants get a chance to reproduce while the pollinators get a chance to eat food in the form of nectar or pollen
