1.Quiz

2.What is alive? Activity

3.Characteristics of Life Notes

4.REMINDER: Lab Report Due TODAY!

5.REMINDER: Test Thursday!

What is living?Alive Never Alive Once was alive

(Dead)

** In your notebook: Explain why you are sorting them in this way. Be ready to

discuss! **

What is biology?Study of life

Biologists – study the structure, function, growth, origin, evolution, and distribution of living organisms.

Characteristics of life

1. Made of one or more cells2. Displays organization3. Grows and develops4. Reproduces5. Responds to stimuli6. Requires energy7. Maintain homeostasis8. Adaptations evolve over time

Organism

1. Made of one or more cells

Cell – basic unit of life. Each cell has a specific structure and function.

An organism can be…a. Unicellular – one cellb. Multicellular – many cells

Organisms are arranged in an orderly way.

Cells have many parts that contribute to whole.

2. Displays organization

3. Grows and Develops

• Grow - Add mass or more cells• Develop – natural changes during the life of

organism

Produce offspring – pass on DNA!!

Reproduce as a species not individual

4. Reproduces

React to factors outside/inside organism

Examples: Plants and sunPredators/prey

5. Responds to stimuli

Keeping internal conditions stable/within a tolerable range

Example for humans: if body temperature rises, you sweat. if body temperature lowers, you shiver.

6. Maintain homeostasis

Energy is used for growth, development, and maintaining homeostasis

Metabolism - biochemical reactions that acquire & use energy

Can obtain energy through: making food from light energy OR consuming food

7. Requires Energy

Adaption - inherited characteristic that resulted from a change in the species over time

Allows a species to survive long enough to reproduce!

8. Adapts over time

Wednesday September 23rd

In Notebook:Explain why a rabbit is considered an organism (aka – what makes it

ALIVE?)
