The smallest unit that can perform all life processes.
All organisms made of one or more cells
Cells are the basic unit of all living things.
All cells come from existing cells.
Trying to maintain a stable internal environment.
A living thing. Anything that can carry out life processes independently
The tool used make objects appear to be magnified. Also used to see cells.
The process of making a copy or duplicating a living thing.
Process of enlarging something only in appearance such as with a microscope.

What are the six main characteristics of living things? Explain.
Does an organism need all six characteristics to be considered living? Explain.
How are the gills of a fish an example of a characteristic of a living thing? Explain.
When a chameleon changes color, what is that an example of in terms of characteristics of a living thing? Explain.
Mr. Lenet dropped a clear object into the water. It was moving and circling in the water. Mr. Lenet then put “food” into the water. The object kept circling. Give a reason why it is a living or non- living thing.
Cells, reproduction, react to environment, using energy, adapted to environment, growth and development.
Yes. Without one of the characteristics it would not be a living thing.
Gills are an adaptation of a fish to breathe in water, so it is “adapted to environment”.
Color change shows “reacts to environment”.
It is only showing “using energy”. It does not have the other six characteristics so it is non-living.

6. It took several scientists and many years to develop The cell theory. Can scientific theories or laws change over time? Explain why or why not?
7. A microscope has a 4x ocular lens and a 10x objective, what is this microscope’s total magnification? (Hint: to find the total magnification you multiply the ocular x the objective)
8. Give 3 examples of your body showing homeostasis.
9. As magnification increases, do you see more or less the “e”? Explain.
10. As magnification increases, does the field of view increase or decrease?
Yes. Both scientific theories and laws can change over time if new discoveries prove them incorrect. The Cell Theory changed and develop over time.
4 x 10 = 40x magnification.
Hands and face turning red after exercise to get rid of heat.
Perspiring (sweat) after exercise to cool body off.
Pulse rate increasing after exercise to get more oxygen to body.
Less of the “e”. Increase magnification shows less of the object with more detail.
Field of view decreases. Larger image with less of it showing.
