Understand Wind and Insect Pollination Fertilisation

In this worksheet, students will learn how wind and insect pollination takes place and how this process is key for plant reproduction.

Worksheet Overview

Do you understand how flowering plants reproduce with help from insects or the wind?

There are 2 key processes we will focus on in this activity:

Pollination = When pollen is carried by insects or blown by the wind from one flower to another.

Fertilisation = When the nucleus of the pollen grain joins with the nucleus of the ovule.

 

Pollination helps the fertilisation of flowers by passing on their pollen.

Let's look in more detail together...

 

Pollination

During pollination, pollen is moved from the anther of one flower to the stigma of another on the backs of insects or by the wind.

Insect pollinated flowers look very different from wind-pollinated flowers. This is because each type has adapted to transferring and receiving the pollen in this specific way.

But how can you tell if a flower is wind or insect-pollinated?

 

  Insect pollinated  Wind pollinated
 Brightly coloured petals?  Yes - to attract insects  No - not needed
 Scented?  Yes, with nectar - to attract insects  No - not needed
 Lots of pollen grains produced?  No, just a few - insect transfer is very efficient  Yes - most are lost in transit
 Male part (anther) inside or outside flower?  Inside - to brush against insects as they feed on nectar deep inside  Outside - to release pollen easily
 Female part (stigma) inside or outside flower?  Inside - the brush against insects and receive pollen grains as they feed on nectar deep inside  Outside - to catch drifting pollen grains easily

 

Fertilisation

 

If a pollen grain (the male gamete) successfully lands on the stigma of a flower of the correct species, it will trigger a pollen tube to grow through the tissues of the flower until it reaches an ovule (the female gamete) inside the ovary. Once it reaches the ovary, the nucleus of the pollen grain joins with the nucleus of the ovule. This is fertilisation. Then, the fertilised egg develops into a seed.

 

That was a lot of information to take in! So, let's consolidate your knowledge by tackling some questions...

Over to you.
