Science Test

Cell Substances and Microscope

Arm The part of the microscope that you carry the microscope with.
Base Supports the microscope.
Body Tube The long tube holds the eyepiece and connects to the objectives.
Diaphragm Controls the amount of light going through to the specimen.
Coarse Adjustment Used for focusing on low power.
Eyepiece Where you look through to see the image of your specimen (10x).
Fine Adjustment Used to fine tune the focus of your specimen after using the coarse adjustment.
Nosepiece It holds the objectives.
Objectives (Low, medium, high) It gives the magnification.
Specimen An individual animal, plant, piece of a mineral, etc., used as an example of its species or type for scientific study or display.
Stage It has a hole in that allows light through the specimen.
Stage Clips Shiny clips on top of the stage which holds the slide in place.
Light Source (What is it?) A source that gives light.
Ocular Lense Another word for eyepiece. Where you look through to see the image of your specimen.
DNA A nucleic acid.
ATP Adenosine triphosphate is the major energy-carrying molecule in cells. The energy in carbohydrates and lipids must first be transferred to ATP, which then provides fuel for cellular activites.
Carbohydrate (What are they made of) Are molecules made of sugars.
Simple Carbohydrates Are made up of one sugar molecule or a few sugar molecules linked together.
Complex Carbohydrates Are made of hundreds of sugar molecules linked together. (Usually stored by organisms)
Lipid Are compounds that cannot mix with water.
Phospholipids (What are they and what are their three purposes) Are the molecules that form much of the cell membrane, which serves the purpose to store energy, act as protective membranes, and communication.
Protein Are large molecules made up of amino acids. They serve the purpose to use their enzymes to start or speed up chemical reactions in cells, transport, and are used as structural support.
Nucleic Acid Are large molecules made up of subunits called nucleotides; sometimes called the blueprints of life because they contain genetic information. They include instructions for cell growth, cell reproduction, and cell processes to respond to their environment
Amino Acids A simple organic compound containing both a carboxyl (—COOH) and an amino (—NH2) group.
Hemoglobins Is a type of protein.
Magnification of Low Power Objective 10x X 4x=40x
Magnification of Medium Power Objective 10x X 10x =100x
Magnification of High Power Objective 10x X 40x =400x
Cell Theory (What does it state, what is the cell, and what is it?) States that all living things are made of one or more cells; the cell is the smallest unit of life; all new cells come from preexisting cells.
Early Scientists (Name them) Robert Hooke, Matthias Schleiden, Theodor Schwann, and Rudolf Virchow.
Year and What He Did : Robert Hooke 1600s - Built a microscope and observed and named cells.
Year and What He Did : Matthias Schleiden 1838 - Concluded that all plant parts were made of cells.
Year and What He Did : Theodor Schwann 1839 - Concluded that all animal tissues were made of cells.
Year and What He Did : Rudolf Virchow 1858 - Stated that all cells could form only pre - existing cells.
State what All Early Scientists' Theories Led To THE CELL THEORY!!! (What caused it to be)
Macromolecules Substance that forms from joining many small molecules together.
