Part 1- Magnification Flashcards
what is the equation for magnification?
<p>Mag powers x mag power of eye piece of objective lens Mag = magnification</p>
<p>What what is an organelle? </p>
<p>Nuceuls/ A membrane bound structure in the cytoplasm of a cell. </p>
<p>What is a Nucleus? </p>
<p>Controls the activities of the cell. Contains genetic information. </p>
<p>What is the cellulose Cell Wall? </p>
<p>Made of cellulose which strengthens the cell. </p>
<p>What is the cell membrane? </p>
<p>Controls the passage of the substances in and out of a cell. </p>
<p>What is chloroplasts? </p>
<p>Contain chlorophyll, they absorb light energy used in photosynthesis to make glucose. </p>
<p>What is a Permanent Vacuole?</p>
<p>Space filled with cell sap, when full this supports the cell. </p>
<p>What is Mitochondria? </p>
<p>Respiration takes place which released energy. </p>
<p>What is cytoplasm? </p>
<p>Liquid gel where most of the chemical reactions take place needed for life to take place </p>
<p>What are Ribosomes? </p>
<p>Where proteins are made- protein synthesis. </p>
<p>Meaning of magnification? </p>
<p>How much bigger a sample appears to be under the microscope than it is in real life.
Overall magnification:
Obj lens x eye piece lens
Obj= objective </p>
<p>What does resolution mean? </p>
<p>The ability to distinguish between two separate points on an image. i.e the amount of detail. </p>
<p>What is (mm)? </p>
<p>Millimetre </p>
<p>What is (upside down h then m)?
| </p>
<p>Micrometer </p>
<p>What is (nm)?</p>
<p>Nanometre </p>
