What's the difference between an electron micrograph and electron microscope?
The difference between an electron micrograph and an electron microscope is that an electron micrograph is a picture taken from an electron microscope.

It's the process of moving waste out.
What is diffusion?

If I look through the eyepiece on a compound light microscope with the medium-power objective lens, what will the magnification power be?
100x
200
They are the energy producers in the cell.
What is mitochondria?
200
This type of cell has a cell membrane but not a cell wall.
What is an animal cell?
200
When the rate of water particles moving into and moving out is the same.
What is a normal and healthy cell?

The examples are - HIV - chicken pox - cold sores - flu
What are some examples Viruses?
300
What piece on the compound light microscope holds the objective lenses?
The revolving nosepiece.
300
It is an example of non living things that are able to reproduce.
What are viruses?
300
It is a type of cell whose organelles are surrounded by membranes.
What is the characteristic of an Eukaryotic cells?
300
The movement of particles from an area of high concentration to an area of low concentration.
What is diffusion?
300
What is in a virus?
DNA, so that it can reproduce itself.
400
If I look into my eyepiece and see that my image in in the bottom right corner, how do I get it to the center?
down & right
400
The organelle that breaks down unwanted parts of the cell.
What is lysosome?
400
This cell has chloroplast.
What is a plant cell?
400
It is the movement of water particles.
What is Osmosis.
400
What is the way viruses occur?
They inject themselves into a cell and send hereditary material so that it "tricks" the cell into producing more viral heredity material and proteins. New viruses form inside the host cell and are released when the host cell explodes and destroys itself.

Most people can only see dots separated by 0.1 mm (or more).
What is the average resolving power of our eyesight?
500
1. the cell is the basic unit of life. 2. all living things are made up of one or more cells. 3. all cells come from other living cells.
What is the cell theory?
500
To protect and provide support for the cell.
What is cell wall?
500
This organelle allows only some substances through.
What is selectively permeable membrane?
