Title: Introduction to Cells


1
Introduction to Cells
  • Unit 4

2
PRE-WARM UP
  • Start a new Table of Contents Life Science
    Molecular Biology
  • Write your homework leave it to be stamped
  • MAKE SURE YOUR YOU HAVE SOMETHING TO CORRECT YOUR
    TEST WITH!

Photosynthesis Cellular Respiration Homework 3
3
PRE-WARM UP
  • On page 1 of your notebook, answer the following
    questions
  • What does it mean to be alive?
  • How do you determine if something is living?
  • What do the words biotic abiotic mean?

4
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
BIOLOGY
  • BIO Life
  • OLOGY study of
  • BIOLOGY Study of Life!

7
5 Characteristics of Living Things
  • Organized structure
  • Made of cells!
  • Grow and Develop
  • Respond to Environment
  • Reproduce
  • Need/use energy

8
Quick Comprehension !
  • Whiteboards ready!
  • Living (L)
  • Non-living (N)

14
Lets Start With Organized Structure
  • Organism- A living thing made up of AT LEAST one
    cell (most have many cells)
  • Wait a Minute!....Whats a cell???

15
What is a cell?
  • Cell- the smallest unit of any living thing

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 ?

21
Quick Comprehension !
  • What determines if something is living?

22
Quick Comprehension !
  • Whats an organism ?

23
Quick Comprehension !
  • What is this cell theory and why do I
    care?

24
Quick Comprehension !
  • What are the 2 types of organisms?

25
WellThere are also 2 Types of Cells
Eukaryotic
Prokaryotic
26
2 Types of Cells
  • Eukaryotic Cell
  • Prokaryotic Cell
  • NO NUCLEUS
  • EXAMPLE bacteria cells (unicellular)
  • HAS A NUCLEUS
  • EXAMPLE plant and animal cells (multicellular)

Nucleus
What is the exception to the rule?
27
Quick Comprehension !
  • Whiteboards Ready!
  • Multicellular or Unicellular
  • AND
  • Eukaryotic or prokaryotic
  • ME UP

28
Unicellular or multicellular?
  • E. Coli
  • Bacteria Cell

Eukaryotic or prokaryotic?
29
Unicellular or multicellular?
  • Human Red Blood Cells

Eukaryotic or prokaryotic?
30
Unicellular or multicellular?
  • Fungi Cell

Eukaryotic or prokaryotic?
31
Unicellular or multicellular?
  • Human Cheek Cells

Eukaryotic or prokaryotic?
32
Unicellular or multicellular
  • Onion Root Cells

Eukaryotic or prokaryotic
33
Unicellular or multicellular?
  • Spiral Bacteria

Eukaryotic or prokaryotic?
34
Unicellular or multicellular
  • Leaf Cells

Eukaryotic or prokaryotic?
35
Unicellular or multicellular
  • Protists

Eukaryotic or prokaryotic?
36
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!!!!

37
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

38
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!
  • DO NOW Read the Photosynthesis Cellular
    Respiration article and answer the questions
  • HOMEWORK Create a Venn diagram or chart on the
    back to compare contrast the processes!

39
HOMEWORK
  • Complete the reading on Photosynthesis Cellular
    Respiration and answer the questions.
  • DONT forget to create the Venn diagram on the
    back!!

40
Extra Credit Opportunity
  • Discovery of Cells 10 points
  • Research the following information and write a
    well crafted paragraph about it
  • When was the microscope invented?
  • Who invented the microscope?
  • When was the first cell discovered?
  • Who discovered it?
  • Add 2 additional facts that you found that
    support this topic and its importance to the
    field of biology
