Can I describe the processes of wind and insect pollination? Can I explain how plants are adapted to be wind or insect pollinated? Share new information What is pollination? Just as with humans, the formation of a new plant begins with fertilisation. The pollen must fertilise the ovule. For this to happen the pollen grain must get from the anther to the stigma. How could it do this? Share new information There are two main methods of pollination: Insect Wind What do you think the advantages and disadvantages are of these two types of pollination? ACTIVITY……………….. Q1. State the difference between self-pollination and cross-pollination. Q2. Describe how wind and insect pollination work. Q3. Explain in detail the difference in structure between an insect-pollinated and a wind-pollinated plant. Challenge: Below are pictures of pollen grains. Decide what type of pollination they represent based on their adaptations. Explain your reasoning. Thinker……………… Heads up!
