1. Ask a question (based on observation)2. Form a hypothesis (inference or

prediction)3. Set up a controlled experiment4. Record and analyze results5. Draw a conclusion

The _____ is the basic unit of life.

1. All Living Things Are Made of Cells

MulticellularOrganisms

UnicellularOrganisms

All living organisms make other organisms like themselves reproducing in two ways:

Asexual reproduction-

Sexual reproduction-

2. All Living Things Reproduce

Single celled organisms reproduce this way. The cell divides creating an exact replica of

itself.

Asexual reproduction produces traits the same as the parents.

Two separate organisms unite to produce an offspring.

Sexual reproduction produces traits different from the parents

This is an advantage as it creates a genetic diversity to assure survival of the species.

DNA

Inherit traits from the parents

A segment of material with instructions for one trait

is called a ________.

3. All Living Things Are Based on a Universal Genetic Code

gene

Grow larger

Differentiation of cell types

4. All Living Things Grow and Develop

To grow and develop

Metabolism- chemical reaction in which an organism breaks down material

5. All Living Things Obtain & Use Materials & Energy

______________ use energy from sunlight or chemicals to make their own food. (green plants use photosynthesis)

______________ get their energy by consuming other organisms.(animals and most bacteria)

Must be ok on the inside

Homeostasis- process by which an organism keeps its internal conditions stable

7. All Living ThingsMaintain a Stable Internal Environment

If body temp drops too low,“shivering” produces heat to warm you up.

If temp is too hot, “sweating” cools you down.

FEEDBACKHOMEOSTASIS involvesinternal __________ mechanisms

Living things evolve

8. All Living Things Change Over Time
