2. Today’s Lesson • Recap of last lesson • Different Habitats • What Is Adaption?

3. Cell Basics • Most living things are made up of cells. Some are made up of a single cell, while some have billions of cells such as humans.

4. Reproduction • There are two main types of reproducing: • Asexual Reproduction • Sexual Reproduction • For asexual reproduction, there is only one parent. They have exactly the same genes and are called clones.

5. Reproduction #2 • In sexual reproduction, there are two parents. The sex organs make sex cells called gametes. • The male sex cell are called sperm and are made in the testes • The female sex cells are called eggs and are stored or made in the ovaries

6. Continued • The sperm and the egg will come together to make a zygote, which is the first cell. • All cells will now reproduce through asexual reproduction until we have specialized cells (such as skin, brain, heart etc).

7. Questions • Name the two different ways cells reproduce. How are they different? • Cells can divide in two different ways. Briefly describe how this can be done for each cell reproduction type.

8. Habitats • Many places of earth may have differences in it’s environment. For example there may be different amounts of sunlight, temperature, water, nutrients, weather etc. • These different areas are called biospheres. Different animals live in different biospheres. For example, you will not see a Polar Bear (thick fur) living long in the Sahara Desert (hot and dry)

10. More Info • Specific animals and plants tend to live in specific areas. For example Koalas need Eucalyptus leaves and frogs need a source of water. Take these away and you won’t have the animal. • A habitat is a community of organisms that requires each other to survive.

11. Questions • Name three different biomes that can be found in Japan. Also give one example of an animal that may live there. • Give one example of a habitat near Yokohama. Name at least 5 organisms which form part of that habitat.

12. Adaptions • Each organism is adapted to live in the habitat where it is found. • For example, some cactus plants look like spiky balls to protect it’s water from other animals. • In general, animals tend to adapt to their physical environment. This gives them a better chance for survival and reproduction.

13. Questions • Name two animals which are expertly suited to the environment and explain why. • Name two animals which would not be suited to a specific environment and explain why.
