How are seeds produced?

We have spent some time looking at seeds and how they are dispersed. But how does the plant produce (make) seeds in the first place?

We know from our learning that animals (including humans) depend on plants for food and lots more, but plants depend on insects and animals too.

Have you ever seen bees and butterflies on flowers? This is a really important part of plants being able to reproduce, which means to make more plants the same.

Have a look at this clip:


The bees and other insects that visit the flowers are known as pollinators. The plant wants them to visit (remember the job of the flower is to attract insects). The insects are looking for nectar inside the flower, which is sweet and sticky. Some pollen ( a yellow, powder) from the inside of the flower sticks to the bee as it flies off to another plant. When it reaches another plant, some of the pollen from the first plant drops off the bee into the second plant and this helps the plant to grow its seeds. When pollen from one plant is taken to another plant to help it produce seeds, it is called cross-pollination.

Here’s a diagram to help explain this further:


Next time you see a bee or a butterfly on the flower of a plant, think about what an important job they are doing.

There has been a reduction in the number of bees recently. What do you think this could mean? Discuss this with someone at home. Have a look at the clip below:


If you have a garden, how could you help attract bees?
