Pollination & Fertilisation

Pollination is the transfer of mature pollen grains ____________________ of a flower

• from stigma to anther

• from anther to stigma

• from filament to style

• from style to filament

There are two types of pollination which are :

• cross pollination

• sexual pollination

• self pollination

• animal pollination

• water pollination

Pollination is the transfer of mature pollen grains ____________________ of a flower

• from stigma to anther

• from anther to stigma

• from filament to style

• from style to filament

Examples of pollination agents are :

• Water

• Wind

• Animal

• Insect

• Human

-Long filament with big anthers

-Long style and feathery stigma

-Produce large quantities of light pollen grains

-Produce many small flowers

Based on the above characteristics of plants. Identify the plant's pollination agent.

• Insect

• Water

• Animal

• Wind

-Do not have nectar

-Have large amount of pollen grain

-Floating pollen grains

Identify the correct pollination agents for the plant with above characteristics

• Wind

• Insect

• Animal

• Water

When pollen grains land on the stigma, each pollen grain produces _________________

• sugary fluid

• pollen tube

• micropyle

• style

Pollen tube carrying two male gametes grow down through the style and into _______________________

• ovule in the ovary

• ovary of the flower

• ovule in the petal

• ovule in the sepal

Which process happens first...

• Pollination and then fertilisation

• Fertilisation and then pollination

What is fertilisation?

• The process of transferring the pollen from one flower to another

• The fusion of the male and female gamete

• The growth of an embryo
