Lesson details

Key learning points

  1. Pollination is the transfer of pollen from one flower to the stigma of another flower.
  2. Plant offspring grown from seeds will have a combination of characteristics of their two parent plants.
  3. Selective breeding involves producing offspring from parents that have desirable characteristics.
  4. Selective breeding can create new varieties of good crops, with higher resistance to pests and disease.
  5. Artificial pollination can be done by hand to produce offspring with desired characteristics.

Keywords

  • Pollination - Pollination is the transfer of pollen from one flower to the stigma of another flower.

  • Parent plant - A parent plant is a plant that has reproduced and created offspring.

  • Characteristics - A characteristic is a feature or property of something that we can use to help identify it.

  • Offspring - Living things create offspring when they reproduce.

  • Artificial pollination - Artificial pollination is carried out by humans, and does not require the help of animals, such as insects, or the weather.

Common misconception

Pupils may not understand how plants of the same species can vary from one another and assume they are all the same because the differences are not obvious.

Explain that plants can have different characteristic within a species, such as size and shape of fruit or colour of flowers.

Encourage pupils to look at the different types of produce available next time they visit a supermarket and think about how they may have been selectively bred. For example, they could look at the range of apples, tomatoes or orchids on sale. You could also share photos of their own local stores.
