In Notebook:How do you determine the size of an object when looking through a
microscope?
Today’s Learning Targets
Agenda:
1.Quiz
2.What is alive? Activity
3.Characteristics of Life Notes
4.REMINDER: Lab Report Due TODAY!
5.REMINDER: Test Thursday!
**Please turn in the video consent forms ASAP! Thank you!**
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?)
