1. Characteristics of Life
Mr. Dirienzo

2. WARM UP What does it mean to be living?
List 5 different things you see in the room you think are living (BIOTIC)…
List 5 different things in the room you think are non living (ABIOTIC)…

3. WARM UP
What are the characteristics that classifies it as living?

4. Characteristic 1 Made of one or more cells
Cells are the basic unit of life
They can be multi-cellular such as human cell or unicellular like a bacteria cell.
Strep throat Bacteria – living organism
Human – Living organism

5. Characteristic 2 Displays organization
Arranged in an orderly way is organization
The organism whether unicellular (one cell) or multi-cellular (many cells) are organized based on different structures within each of the cells that have specific roles and functions.

6. Characteristic 3 Grows and Develops

Growth is an addition of mass to the organism, forming new cells and structures
Throughout time the organism advances in these structures, thus becoming developed.
Example - birds

7. Characteristic 4 Reproduces
Organism reproduces and passes along traits form one generation to the next.

8. Characteristic 5 Responds to stimuli
Organism have external environments (all the things that’s surround it – air, land, water, soil, etc.)
Anything that is part of the organism’s environment and causes a reaction from the organism is a stimulus

9. Characteristic 6 Requires energy Energy fuels life!
Energy comes from food, unicellular and plants use the sun to make their own food.
Organisms that cannot make their own food must consume other organisms.

10. Characteristic 7 Maintains Homeostasis
Homeostasis- regulation of internal conditions
Ex- sweating
Any disruptions in homeostasis, and not restored death may occur

11. Characteristic 8 Adaptions evolve over time
An inherited characteristics that results in changes to a species over time, this is an adaptation

12. Levels of Biological Organization

13. Intro to Cells Cells - smallest unit of life Two Types 1. Prokaryotic
2. Eukaryotic

14. Prokaryotic Cells - no nucleus - nuclear membrane
- organelles within the cytoplasm
- single celled organisms

15. Eukaryotic Cells - true nucleus - organelles within the cytoplasm
- usually larger
- multicellular organisms
