Lesson 1 :
Curriculum standards : 6.2
Every day millions of living things die.
Organisms do not live for ever.
Why is there still life on Earth? Pic cat
Before most organisms die,
they produce new organisms like themselves.
In many animals a new life
starts when the nucleus of a sperm
(a specialized cell from the father)
Fuses (combines) with the
nucleus of the egg
(a specialized cell from the mother).
We call it Fertilization.
Question:
What do plants have instead of Sperms?
Reproduction is producing young, so that the species continue to exist. . بقاء الاع ف االستمرار و لك نحافظ على االنو ,ج الصغار هو انتا: التكاثر
Fertilization is the fusion of an egg with a sperm to form a zygote
. هو اتحاد بن الحوان المنوي و البوضه النتاج بوضه ملقحة :-األخصاب

Different animals fertilize their eggs in different ways.
Fertilization in Vertebrates:
External fertilization
Internal fertilization
Fish and Amphibian Birds and reptiles
Mammals
Young Develop inside uterus
young young
Develop in water Develop on land
The female frogs and fish lay thousands of eggs in water, males will
wait for the female frogs and fish to lay the eggs then they will
release the sperms in water.

Fertilization happens when a sperm and an egg meet by chance.
The mothers do not take care of their young.

Internal fertilization: Fertilization happens inside the mother’s body.

External Fertilization: fertilization takes place outside the body . أخصاب حدث خارج الجسم : الألخصاب الخارج

Mammals, reptiles and birds have a different, more efficient form
of reproduction: The sperm and egg meet and fuse (combine) inside
the mother’s body.
a. Birds and reptiles lay their eggs on land. The eggs are
covered by hard shells. They contain lots of stored food.
The mothers take care of their young until they can live on
their own.

b. Most mammals are different; their young grow in a special organ
inside the mother’s body. We call it a Uterus.
The mother will take care of the young and feed them milk. . الرحممعظم الثدات نمو صغارها ف عضو خاص داخل جسم األم دعى -

There are two types of fertilization, one that
happens outside the mother's body we call
it External fertilization and one that happens
inside the mother's body, we call it Internal
