Gavin Morgan 9/23/2015 Chapter 4 2-Point Notes Cell theory is the unifying foundation of cell biology: 1. All organisms are composed of one or more cells. 2. Cells are the smallest living things, and arise only by division of a previously existing cell. Cell size is limited: 1. As the size of a cell increases, the length of time for diffusion from the outside membrane to the interior of the cell increases as well. 2. Some cells, such as skeletal muscle cells, have more than on nucleus, allowing genetic information to be spread around a large cell. Microscopes allow visualization of cells and components:

Name_________________________________Date_______________________Pd._____ Cell Review Worksheet Complete the following table by writing the name of the cell part or organelle in the right hand column that matches the structure/function in the left hand column. A cell part may be used more than once. Structure/Function Cell part 1. Stores material within the cell 2. Digests excess or worn-out cell parts, food particles and invading viruses or bacteria 3. Site of protein synthesis 4. Jelly-like substance in the cell 5. Organelle that manages or controls all the cell functions in a eukaryotic cell 6. Contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color

Cells & Transport Study Guide Cell Theory 1) All living things are made up of cells 2) Cells are the basic units of structure and function in an organism 3) New cells are produced from existing cells Scientists: 1665 Robert Hooke Coined word ?cell? Looked at cork under microscope 1674 Anton van Leeuwenhoek Perfected the simple microscope Discovered protozoa 1838 Matthias Schleiden Discovered/published fact that all plants are made of cells 1839 Theodor Schwann Discovered/published fact that all animals are made of cells 1855 Rudolf Virchow Discovered/published fact that all cells come from preexisting cells 1931 Janet Plowe Demonstrated that a cell is a physical structure 1970 Lynne Margulis Created endosymbiotic theory Endosymbiotic Theory

Chapter 4: A Tour of the Cell Types of Cells Prokaryotic- a type of cell lacking a membrane-enclosed organelles Bacteria and Archaea DNA in the nucleoid which is not membrane-bound Eukaryotic- a type of cell with membrane bound organelles Protists, Plants, Fungi, and Animals Contian a membrane-bound nucleus Contain organelles and cytoplasm Both: Have ribosomes Plasma membrane Jelly-like cytosol Chromosomes *As the volume of a cell grows, the surface area increases proportionally because more plasma membrane needed to transfer necessary materials for the metabolic processes *Different organelles increase complexity of the cell because each organelle has a specific function, whit allows multiple activities to be going on in the cell at once The Nucleus

Maia Regman Mrs. Magnan Biology Honors 28 October 2013 Plant and Animal Cells Objective The objective of this lab was to learn what a microscope reveals about plant and animal cells. The completion of this lab should teach the participant the differences between plant and animal cells and how to examine samples of the covering tissues of a plant (the onion) and of an animal (the participant) using the epidermis and cells from a cheek swab of epithelial tissue. Materials Packet Pages L14 to L16 Onion Chunks Compound Microscope Microscope Slides Covers Slips Water Pipette Lugol?s Iodine Solution Tweezers (optional) Paper Towels Flat Toothpicks Procedures. Part A: Cells of the Onion Epidermis Gently peel off one of the thin layers of the inside of the onion chunk.

Chapter 7 A View of the Cell The Discovery of Cells The History of the Cell Theory The first person to record looking at water under a microscope was Anton van Leeuwenhoek. Robert Hooke used a compound light microscope to study cork, the dead cells of oak bark. Matthias Schleiden studied plants under a microscope and concluded that all plants are made of cells. Theodore Schwann studied animal cells and concluded that all animals are made of cells. Rudolf Virchow hypothesized that cells divide to form new cells & all cells come from preexisting cells The Cell Theory: All organisms are composed of one or more cells. The cell is the basic unit of organization of organisms. All cells come from preexisting cells.
