• Next Friday: Unit 1 Test

Quiz 1: Scientific Method

• Clear EVERYTHING off your table except a pen/pencil.

• Leave your quiz face down until all the quizzes have been passed out.

• Eyes on your own paper. No notes. No talking.

• Turn your quiz back over, face down when you finish.

• Questions?

BINDERS

• Biology Handbook – place in the back of the binder.

How do you know you are alive?

• What traits (characteristics) do you think ALL living things share?

• How can you tell if something is living?

Characteristics of Living Things

• Biology is the study of _______ and __________ things

• All living thing, called ______________, share some common characteristics and life functions. All organisms must carry out all of the same life processes, or activities, in order to be considered “alive.”

• There are 6 characteristics of life:

lifeliving

organisms

Life Characteristic #1• Genetic Code: All living things are made

from a universal

Genetic code (DNA, RNA)

This is also known as

heredity.

Life Characteristic #2

• All living things are made up of one or more cells.

Life Characteristic #3

• Living things can obtain and use energy.

• This is also called METABOLISM

Life Characteristic #4

• change over time a population. (They evolve)

Life Characteristic #5

• Living things are able to maintain homeostasis. (internal balance)

• Define:

The ability to maintain a stable (balanced) internal environment

Life Characteristic #6

• Living things are able to adapt or respond (adjust) to their environment.

Let’s investigate more!

1. Read the directions.

2. Define each term.

3. Write a hypothesis.

4. Visit each station with your partner and complete the chart.

Let’s do one together…

More…

• Living things also have to be able to accomplish certain life processes or activities. A living thing must be able to do ALL 8 of these “STERNGRR” processes.

Atoms / Elements

Molecules

Cells

Tissues

Organs

Systems

Organism

STERNGRR (life processes) starts here!

Life Processes

STERNGRR

Synthesis

to make or build

to combine

SYNTHESIS examles

• photosynthesis: makes compounds using __________ energy: (PLANTS)

• chemosynthesis: makes compounds using _________________ energy: (BACTERIA)

• Protein synthesis: cells have structures called ribosomes that make proteins (ALL cells)

sunlight

chemical

• Plants use light energy of the sun to SYNTHESIZE

(make) food

Life Processes

STERNGRR

TRANSPORT

• DOES NOT MEAN movement from place to place

• Transport is the movement INSIDE the organism i.e. vascular tissue in plants

Transport Example

• Plants have vascular tissue – (xylem to transport water in the stem) – (phloem to move sugar and water through the

stem)

• The blood is the body’s TRANSPORT system for moving

oxygen, nutrients and wastes from one place to another.

Circulatory system. In animals, can be open or closed

Life Processes

STERNGRR

EXCRETION examples

• Transpiration in plants: how plants get rid of __________

• Diffusion of waste gasses (like _______) out of cells through the cell membrane

water

CO2

• EXCRETION helps an organism to maintain

homeostasis by getting rid of waste materials

Life Processes

STERNGRR

Reproduction =

to make more individuals

When a species makes more of its own kind

REPRODUCTION

2 kinds: • SEXUAL: (2 parent cells)

– Spores– Pollination

• ASEXUAL: (one parent

cell)– Mitosis– Binary fission

Life Processes

STERNGRR

NUTRITION

• heterotroph: eats different foods for energy (animals, bacteria, fungi)

OR

• autotroph: makes own food internally (plants, algae)

Life Processes

STERNGRR

Growth (and Development)

to get bigger and change

When an organism increases in size or number

GROWTH examples

• _____________________ (complete vs. incomplete)

• Plants and animals use the process of MITOSIS to make more cells that allows for growth

Metamorphosis

GROWTH is getter larger

DEVELOPMENT is changing stages during one’s life

cycle

Life Processes

STERNGRR

Respiration =

Turning food into usable energy

RESPIRATION

• Respiration: turning food into usable energy with the exchange of ______

IS NOT ALWAYS BREATHING!

gases

RESPIRATION is the process used by a living organism to break down food and produce energy

RESPIRATION examples

1. _______________when cells use oxygen to break down glucose for energy (ATP)

2. _________________: when cells produce ATP (energy) without oxygen present

AEROBIC

ANAEROBIC

Life Processes

STERNGRR

REGULATION examples

Regulation: homeostasis1.Sweating to keep cool and shivering to

stay warm (regulates body temperature)

2.Insulin hormone regulates blood

3.Stomata (openings/pores) on plant leaves regulate _______ exchange and _____________ loss

sugar

gaswater

• REGULATION includes responding to stimuli and making adjustments to help maintain homeostasis

CASE STUDY!

1. Work with your partner.

2. Create a STERNGRR +6 check list

3. Read the “Safari Scenario” about the discovery of a strange object and determine whether it is living or non-living.

4. As you read the scenario, see which terms can be checked off. Give examples of the terms that are met.

5. If all terms can be checked off, the item is living. If not, the item is nonliving.
