WARM UP

• Surprise!!
• We are going outside for our warm-up!

5
Living vs. Nonliving

• TASK 1
• Make a list of 5 living 5 non-living things

• TASK 2
• Make a list of characteristics you used to
  determine if something living

6
4 Characteristics of Living Things

• Organized Structure
• Grow and Develop
• Respond to Environment
• Reproduce

7
Quick Comprehension !

• Whiteboards ready!
• Living (L)
• Non-living (N)

Lets Start With Organized Structure

• Organism- A living thing made up of AT LEAST one
  cell (most have many cells)
• Capable of growing and reproducing
• Wait a Minute!....Whats a cell???

15
What is a cell?

• Cell- the smallest unit of any living thing
• ALL living things are made of cells.
• A cell or group of cells carry out ALL activities
  in a living things body.

16
2 Types of Organisms One Cell or Many Cells?

• Unicellular

• Multicellular

• Organisms made up of only ONE cell
• Examples amoeba, bacteria

• Organism made up of MANY cells
• Examples plants, animals, humans

17
OKThe truth about cells

• The reason cells are important to life is
  summarized in the Cell Theory
• Every living thing is made of one or more cells.
• Cells carry out the functions needed to support
  life.
• Cells can only come from other living cells.

18
Cell Theory Example

• Every living thing is made up of one or more
  cells.
• A polar bear is a multicellular organism.

3. Cells come only from other living cells. Each
polar bear cub began as a single cell. That
single cell split into 2, those 2 split into 4
and so on
400x
2. Cells carry out the functions needed to
support life. Every type of cell has a different
function, for example fat cells provide extra
energy as well as insulation.

Quick Comprehension !

• What Is Biology again?

21
Quick Comprehension !

• What determines if something is living?

22
Quick Comprehension !

• Whats an organism again?

23
Quick Comprehension !

• Waitwhat are organisms made up of?

24
Quick Comprehension !

• What is this cell theory and why do I
  care?

25
Quick Comprehension !

• What are the 2 types of organisms?

26
WellThere are also 2 Types of Cells
Eukaryotic
Prokaryotic
27
2 Types of Cells

• Eukaryotic Cell

• Prokaryotic Cell

• HAS A NUCLEUS
• EXAMPLE plant and animal cells (multicellular)

• NO NUCLEUS
• EXAMPLE bacteria cells (unicellular)

Nucleus
28
Quick Comprehension !

• Whiteboards Ready!
• Multicellular or Unicellular
• AND
• Eukaryotic or prokaryotic
• ME UP

29
Unicellular or multicellular?

• E. Coli
• Bacteria Cell

Eukaryotic or prokaryotic?
30
Unicellular or multicellular?

• Staphylococcus aureus
• (Staph Bacteria)

Eukaryotic or prokaryotic?
31
Unicellular or multicellular?

• Human Red Blood Cells

Eukaryotic or prokaryotic?
32
Unicellular or multicellular?

• Fungi Cell

Eukaryotic or prokaryotic?
33
Unicellular or multicellular?

• Human Cheek Cells

Eukaryotic or prokaryotic?
34
Unicellular or multicellular

• Onion Root Cells

Eukaryotic or prokaryotic
35
Unicellular or multicellular?

• Athletes Foot Fungus

Eukaryotic or prokaryotic?
36
Unicellular or multicellular?

• Spiral Bacteria

Eukaryotic or prokaryotic?
37
Unicellular or multicellular

• Leaf Cells

Eukaryotic or prokaryotic?
38
Tie It TogetherWhat Do All Cells Need?

• Ok, regardless if an organism is unicellular or
  multicellular prokaryotic or eukaryoticwhat do
  they all need to function????
• ENERGY!!!!

39
Where Do They Get Their Energy?

• It Depends
• Animal Cells consume food and their cells
  create energy through the process of CELLULAR
  RESPIRATION
• Plant Cells use the sunlight and their cells
  convert it into energy through the process of
  PHOTOSYNTHESIS

40
But How?

• Read about the 2 processes for now, and next time
  we will see how each part of a cell has a
  specific job to do to make these processes
  possible!
• Read the Photosynthesis Cellular Respiration
  article fill in the chart below it to help you
  understand how the 2 processes are related

41
HOMEWORK

• DAY 1 VOCABULARY
• DEFINITIONS ONLY
• DUE THURSDAY!

42
