What kind of fruits there are. 

 

Repeating

After fertilization

When the egg cells in all the ovules are fertilized, the ovary will start to grow. The ovary will change into a fruit. Seeds can be found inside the fruit. The image shows a pod fruit. 

Fruits

The shape of the fruit says a lot about how the seeds are dispersed (spread). A pod is very long, and some fruits have a lot of pulp. This can often be eaten by animals or humans. 

Seeds

Every seed contains a plant embryo, the beginning of a new plant. The amount of seeds is different for each fruit. This says something about the amount of ovules in the flower. 

Edible seeds

Time to work!
