Some of the cells inside the ovule store food for the seed when it starts to grow.Other cell make the egg nucleus that is needed to make the new plant.

Newly arrived pollen is trapped in a sticky, sugary solution on the top of the
stigma .Each pollen srain grows a long tube that pushes down between the cells to the ovary.

The pollen tube then pushes into an ovule.It releases a nucleus, which combines
with the egg nucleus in the ovule. This is called fertilisation. After fertilisation the
ovule can develop into a seed.

You have grow up a lot in the last few years. You can mix with new people, and
you are more independent. Your body has grown too.All these difference are part

and heavier than girls.

Puberty is the time of the last growth spurt. It starts sometimes brtween 10 and 14 years old.

Your brain makes a hormone that starts it all off.A hormone is a chemical that
controls the activity of other parts of the body.

Your skeleton and muscles grow so that you become taller. Inside your body
your reproductive organs develop.

The growing reproductive organs make other hormones.These cause the
changes we see in our body and in our body in our interests, moods and
emotions. the changes take until the late teens to complete.
