Sexual reproduction
In sexual reproduction
pollen
goes from the stamen of one flower to the pistil of a different, or the same,
flower. This is how most plants reproduce. But how does it happen?
The pollen joins an
ovule
to make a
seed
. This is called
fertilisation
. The pistil grows around the seed into a
fruit
. The fruit falls to the ground and the seed grows into a new plant. But how does it happen?
Asexual reproduction
In asexual reproduction there are no flowers or fertilisation.
Runners
are stems which
grow along the ground.
Buds
grow from the stems
and develop into new plants.
Tubers
are swollen stems
which grow under the ground.
Buds
grow from the tubers
and develop into new plants.
Some plants, such as the
strawberry, use sexual AND
asexual reproduction!
