QUEST REVIEW WITH MISS DELL- If you did not do your homework- If you got one or more wrong the QUEST check

- You would like a further review of the Characteristics of Living Things

All other students- Work on your QUEST

- Read Pages 7-11 and Answer Question 4- Watch Wacky History of the Cell Theory- Explore Understanding Resources

- Brainstorm for your Extended Thinking Adventure (Proposal due Thursday)

The 6 Characteristics of Life1. Cellular Organization2. Made of Similar Chemicals3. Use energy4. Respond to surroundings5. Grow and Develop6. Reproduce

6 characteristics of life video: https://m.youtube.com/watch?v=iuUzQW29Aw8

1. Living things are OrganizedCell- basic unit of structure and function in an organism.

Living thing are made up of small units called cells. Each cell has an orderly structure and contains genetic material – a blueprint for the cell’s organization and function.

Unicellular – one cell.EXAMPLE: Bacteria

Multicellular – more than one cell.

EXAMPLE: Humans!

Entamoeba gingivalis

2. Living Things Contain Similar Chemicals

a. WATER- most abundant chemical in cells

b. Carbohydrates

c. Proteinsd. Lipidse. Nucleic Acids

(DNA)

3. Living things use energy

3. Living things use energyList 3 things for which cells use energy:

REPAIR

GROWTH

MOVEMENT OF MATERIALS; BUILDING MOLECULES

4. All living things respond to their surroundingsStimulus- a change in an organism’s

surroundings that causes the organism to react

Response- an action or change in behavior

5. Living things Grow and develop

Growth- the process of becoming larger

Development- the process of change that occurs during an 0rganism’s life to produce more complex organisms

6. All living things reproduceThe ability to produce offspring that are similar to the

parents.

Spontaneous Generation Theory

Idea that life can spring from nonliving matter.

Most people believed in this theory until the 1600s!

What observations could have supported this theory?

For example, People believed:-Mice came from straw

-Frogs and turtles developed from rotting wood and mud at the bottom of a pond.

-Flies came from rotten meat.

Francesco Redi’s Experiment

How did this experiment disprove spontaneous generation?

DEFINITIONS

Cell- Basic unit of structure and function of living things.

Organelles- structures that make up a cell.

Question 10 &11

How are multicellular organisms organized? Are we just a pile of cells?

6. In Multicellular Organisms:Cells Tissues Organs Organ Systems

7. • Cell- the basic unit of structure and function in living

things (Ex. Nerve Cell)

• Tissue- Group of similar cells that work together to perform a specific function (Ex. Nervous Tissue)

• Organ- Different tissue that work together (Ex. Brain)

• Organ System- Group of organs that work together to perform a major function (Ex. Nervous System)
