1673- ___________________________________ a Dutch microscope maker was the first to see LIVING ORGANISMS. Anton van Leeuwenhoek
12
1665- ______________________ used a microscope to examine a thin slice of cork, dead cells of oak bark and saw “little boxes” He called them “CELLS” because they looked like the small rooms that monks lived in called Cells Robert Hooke

The Cell Theory Fill out the cell theory chart!!!
22
All living things made of cells BUT… organisms can be very different. UNICELLULAR MULTICELLULAR
23
Insert into Notes Unicellular Multicellular Made of one cell Example: bacteria Made of more than one cell Example: plants and animals

Partner Read Prokaryotes are unicellular organisms, found in all environments. Prokaryotes are the largest group of organisms, mostly due to the vast array of bacteria which comprise the bulk of the prokaryote classification. Eukaryotes are generally more advanced than prokaryotes. There are many unicellular organisms which are eukaryotic, but all cells in multi-cellular organisms are eukaryotic. 1. Which type of cell are humans composed of? How do you know? You will have 5 minutes to answer the question on the next slide

ReadAloud—pg 173 Two Basic Cell Types
42
Cells that do not contain internal membrane-bound structures are called prokaryotic cells. The cells of most unicellular organisms such as bacteria do not have membrane bound structures and are therefore called prokaryotes. Two Basic Cell Types
43
A prokaryotic cell does not have internal organelles surrounded by a membrane. Most of a prokaryote’s metabolism takes place in the cytoplasm. 1. Ribosomes 2. DNA 3. Plasma membrane 4. Cell wall Chapter Assessment
44
Cells that do not contain any membrane-bound organelles. Example: bacteria Prokaryotes Take Notes! Topic: Cells
46
Most of the multi-cellular plants and animals we know are made up of cells containing membrane-bound structures and are therefore called eukaryotes. Cells containing membrane-bound structures are called eukaryotic cells. Two Basic Cell Types
47
This eukaryotic cell from an animal has distinct membrane-bound organelles that allow different parts of the cell to perform different functions. 4. Plasma membrane 1. Nucleus 2. Nucleolus 3. Chromosomes 5. Organelles
48
Cells that contain membrane- bound organelles. Examples: amoebas, algae, yeast, animals, plants. Eukaryotes Take Notes! Topic: Cells
50
The membrane-bound structures within eukaryotic cells are called organelles. Each organelle has a specific function that contributes to cell survival. EUKARYOTIC CELLS
51
Human Cell Eukaryotic cells are generally one to one hundred times bigger than prokaryotic cells.
53
Eukaryotes Prokaryotes Both Fill out the diagram using your notes and the text book!!!!
54
Prokaryotes NO membrane- bound organelles cell walls most are unicellular DNA floats freely around small (.001 -.01mm) Both: cytoplasm DNA as genetic material ribosomes Cell membrane CELLS Eukaryotes nucleus & membrane-bound organelles some have cell walls most are multi- cellular large (.01 -.1mm)

61
Announcements: Books assigned—see me after class to get yours Turn in homework! Makeup quiz

63
Popcorn Reading—Sec 7.2 The Plasma Membrane: pg 175 – 178 IF TIME
64
Homework Reading & Vocab: New Vocab words to add to foldable: plasma membrane selective permeability phospholipid fluid mosaic model transport proteins
65
CELL SIZE Typical cells range from: 5 – 50 micrometers (microns) in diameter http://facstaff.bloomu.edu/gdavis/links%20100.htm
66
How big is a micron ( µ ) ? 1 cm = 10,000 microns 1” = 25,000 microns
67
MULTICELLULAR ORGANISM don’t just contain MANY CELLS. Image from: http://www.isscr.org/images/ES-cell-Fig-2.jpg They have different kinds of cells doing different jobs
68
Cells in a multi-cellular organism become SPECIALIZED by turning different genes on and off Image from: http://www.ncu.edu.tw/~ls/graph/faculty_pictures/whole_time/SLC/SLC_lab-1.jpg Cell Specialization =DIFFERENTIATION
69
SPECIALIZED ANIMAL CELLS Muscle cells Red blood cells Cheek cells
70
Specialized Plant cells Guard cells Xylem cells Pollen

Get your Biology Book! Responsibilities & Expectations: 1. Keep it in a SAFE place (at home)—DO NOT LOSE IT! *you do not need to bring it to class (for now) unless I tell you to *if it’s lost or stolen you will owe a LOT of money! *Harper teachers/staff will track you down! *You MUST have the same number at the end of the year as the one you get today, in other words, turning in ANY book at the end of the year doesn’t cut it… it MUST BE YOURS! 2. Do not write on it, rip any pages, or damage it in any way 3. USE IT!—Every time you open it up, your grade will improve!
