1. What do all living things have in common?

2. Living things have several characteristics that distinguish them from non-living things.
1. Living things grow in size, reproduce and are able to repair themselves.
Repair worn or injured parts
Grow in size
Produce offspring

3. 2. Living things require energy.

4. 3 Living things respond to changes in their environment.
Animals try to escape from predators.
Responses do not always cause motion.
Some responses occur within the living thing and are not directly observable.
e.g. an animal’s metabolism may slow down when an animal is cold hungry or thirsty which affects the bodily functions and not the motion.
Plants grow in the direction of moist soil…and the sun.

5. 4. Living things have a life span.

6. 5. Living things produce waste.

7. What two characteristic are described in the following statement?
Check your learning…
Characteristic of living things
Non-living things with similar characteristic
Grow in size, reproduce, are able to repair themselves
Require energy
Have a life span
Responds to things in their environment
Living things produce waste
A car produces waste in the form of fumes but is not alive
What two characteristic are described in the following statement?
“A human begins life as a single cell, whereas an adult is made up of trillions of cells” 1. 2.

8. Introducing the amazing cell….
The basic structural and functional unit of all living things!

9. Living or Non-living? 1. Check your learning….2.
3. E-Learning Ontario
Are you ready to take care of an Amoeba ?

10. Introducing… The first true cells!
You are very welcome!!!!
First were anaerobes (lived without oxygen)
About billion years ago
Became photosynthetic bacteria
Began producing oxygen which built up in Earth’s atmosphere

11. 1. All living things are composed of one or more cells.
The theory that states that all living things consist of cells, that the cell is the basic structural and functional unit of life, and that all cells come from pre-existing cells.
The Cell Theory
Investigate the functions and processes of plant and animal cells
Investigate the basic structure and function of plant and animal cells
1. All living things are composed of one or more cells.
2. The cell is the basic unit of life.
3. All cells come from pre-existing cells.

12. Does Size Matter? Cells have a wide variety of sizes.
Smallest: Bacterial
Not more than 10μm ( 10 1/1000 of a mm)
Typical human cell:
About 100 μm
Largest cell: Nerve cell of large animals
About 10 m in length but very narrow
Bacterial cell
Human
Largest cells
1 cm in diameter
10 cm in diameter
m long
Compare the sizes of cells
