Do Now!! 
  • List 5 things that are living and 5 things that are not living
  • What do the living things you listed have in common that separate them from the non-living things?
objectives
Objectives
  • Identify the 4 unifying themes of Biology.
  • Explain what characteristics an organism must have to be considered alive.
unifying themes of biology
Unifying themes of Biology
  • 1. All living things share common characteristics
  • 2. All living things share common needs
  • 3. Living Things meet their needs through interactions with the environment
  • 4. The types and numbers of living things change over time
1 all living things share common characteristics
1) All Living Things Share Common Characteristics

Unicellular

  • Small, hard to see
  • directly exchange nutrients and waste with environment

Multicellular

  • Work together
  • cells have specialized jobs and work together to keep organism alive

a) Made of 1 or more cells.

common characteristics cont
Common Characteristics (cont.)

b) Organized

  • All parts work together to take in nutrients and remove waste
  • Body plan allows it to survive in its environment
common characteristics cont1
Common Characteristics (cont.)

c) Growth and Development

*Cell division and cell differentiation*

d) Responds to stimuli

2 all living things share common needs
2) All Living things share common needs.

a) We need energy!!

  • Energy is the ability to do work.
  • The sun is the ultimate source of energy!
energy cont
Energy (cont.)
  • Can come from food and is converted into usable form, think calories
  • Energy moves along food web, only 10% of energy transferred to each level
how do we get our energy
How do we get our energy?
  • Autotroph (Producers)
  • Heterotroph (Consumers)
c ommon needs cont
Common needs (cont.)

Regulation of an organism’s internal conditions to maintain life

Temperature

Blood sugar levels

B) Homeostasis:

Blood Pressure

c ommon needs cont1
Common needs (cont.)

C) living space

  • Serves as protection
  • Sources of nutrients
  • Area to grow and develop
all organisms need to adapt
All organisms need to Adapt

Common needs (cont.)

D) Adaptations:

  • characteristic of an organisms that allows it to better survive in its environment

*Organisms within a species must adapt to changing environments or they will become extinct!!*

Ex: A cheetah’s speed, camouflage, etc.

3 living things meet their needs through interactions with the environment
3) Living Things meet their needs through interactions with the environment
  • A) Environment:everything that surrounds an organism.
    • Living factors (biotic factors)
    • Non-living factors (abiotic factors)
      • Ex: sunlight, temperature, climate, rocks, etc.
interactions with the environment cont
Interactions with the Environment (cont.)
  • B) Species Interactions-2 or more things affecting each other.
think pair share
Think-Pair-Share
  • Name at least 5 DIFFERENT interactions occurring in the following picture.

  • List 2 characteristics that all living things share.
  • List 2 needs that all living things share.
  • What is the scientific term for a living thing? Non-living?

  • Read the handout for instructions
  • Assignment will be due the next class.
  • You must make an ORIGINAL CREATURE!!

Quiz
  • You will have a “quest” on MONDAY 9/26
  • Review the study guide, your notes, the powerpoint on the website, and the jeopardy game to help you study.
  • We will do a quick lab tomorrow and then play jeopardy to review.
