From flower to fruit

The idea

After fertilisation the ovary enlarges into a fruit and the ovules develop into seeds, which are dispersed by wind, water or animals and germinate when water, air and temperature are favourable.

Inside a mango

On a plant, a flower fades away and a small fruit starts to grow in its place.

Which part of the flower do you think enlarged into the fruit?

• The ovary
• The petals
• The pollen

Fruit, seeds, new plants

The ovary grew into the fruit and the ovules grew into seeds. The seeds are carried away and can grow into new plants. Sexual reproduction in plants also creates variation.

After fertilisation the ovary enlarges into a fruit and the ovules develop into seeds. Seeds are dispersed by wind, water or animals and germinate when water, air and temperature are favourable.

Notes

The ovary becomes the fruit, the ovules become seeds, which are dispersed and germinate when conditions are favourable.

How are seeds dispersed?

A seed germinates and grows into a new plant when…

• fruit — correct. Yes!
• flower. The flower is the reproductive organ. After fertilisation the ovary becomes a fruit.
• pollen grain. Pollen grains are made in the anther.
• petals. Petals are the coloured projections of the flower.
• seeds — correct. Yes!
• fruits. It is the ovary that enlarges into a fruit.
• By their own roots. Seeds are dispersed by wind, water or animals.
• Only by the stamens of the same flower. Seed dispersal takes place by wind, water or animals.
• By wind, water or animals — correct. Yes!
• water, air and temperature are favourable — correct. Yes!
• it is kept dry and cold. The seed needs water, air and a favourable temperature.
• it is still inside the flower bud. Germination happens after the seed is formed and when conditions like water, air and temperature are favourable.
