It's all History
Who is given credit for the naming of a cell after seeing boxlike structures under a simple microscope?
Robert Hooke
What microscope have we been using in class?
Compound Light Microscopes
What organelle makes (synthesizes) proteins in the cell?
Ribosomes
Key property of the plasma membrane that allows some substance to pass through while keeping others out.
Selective Permeability
An unknown cell is determined to contain a nucleus, a cell wall, mitochondria, chloroplasts, and ribosomes.
What kind of cell could this be?
Eukaryotic/Plant Cell
The basic structural and functional unit of all living Organisms.
The Cell
Your microscope has an ocular lens with 15x magnification and you're looking at a specimen at 4x magnification. What is your total magnification?
60
Where are Ribosomes made (synthesized)?
The Nucleolus
Two layers of phospholipids arranged tail-to-tail that composes the plasma membrane
Phospholipid Bilayer
Projections from the cell surface that sweep substance along the surface of the cell.
Cilia
What were the first glimpses of what would soon called cells compared to that gave cells their name.
Cells (small rooms) in which monks live at a monastery.
You're a scientist in a lab and you want high resolution and magnification of structures inside your specimen ---what kind of microscope do you want?
Transmission electron microscope (TEM)
What organelle is studded with Ribosomes and is involved in the synthesis & Modification of Proteins?
Rough Endoplasmic Reticulum
The concept scientist use to describe the fluid nature of the Plasma membrane.
Fluid Mosaic Model
Always occur in pairs and is important for cell division
Centrioles
Literally wrote the book on the Biology of the Cell Surface that made his discoveries accessible to general readers and influenced future research.
Ernest Everett Just
You're looking at a specimen with a compound light microscope and you want to adjust the amount of light that passes through --- what part of the microscope do you use to make this adjustment?
The Diaphragm
This organelle is key in processing and packaging proteins and lipids into vesicles for transport and distribution throughout the cell
Golgi Apparatus/Body
A supporting network of long, thin protein fibers that form a framework for the cell and facilitates movement and other cellular activities.
Cytoskeleton
Term used to describe the Water-Loving polar heads of a phospholipid
Hydrophilic
1. All Living organisms are composed of one or more cells
2. Cells are the basic unit of structure & organization
3. Cells arise only from other cells
What is the limiting factor of a compound light microscope?
The use of light to create a image (resolution)
A damaged cell is unable to properly modify proteins after they are made, which causes the proteins to misfold. What organelle is most likely damaged in the cell?
Endoplasmic Reticulum (ER) - Rough
Thick, rigid, mesh of fibers that surrounds the outside of the plasma membrane-- providing extra protection and support.
Cell Wall
Phenytoin is a prescription drug that is used to treat patients with epilepsy. A side effect of phenytoin is that it can be toxic to mitochondria. What process will be most immediately disrupted by this side effect?
ATP Synthesis (energy production)
