Plants Reproduce

Plants reproduce to ensure the survival of their species. They reproduce in many different ways.

1. Plants reproduce from seed.
    For example, a papaya plant.


                                  flower



                     fruit
                      

                                 seeds


                            plant
                           



The flowers will become fruits that contain seeds in them. When these seeds are planted, they will grow into seedlings and then into young plants.
Tomata, sun flower, balsam and shorea are reproduce from seeds.

                                   Shorea

                       
2. Some plants reprodece from spores. Ferns and mushrooms prodece millions of tiny spores. These spores can be easily carried away by the wind. They can grow into young plants under the right conditions.

When spores land on a moist place where there is food, they will germinate to produce a new plant.
