How do you find total magnification?

Answer 21

Eyepiece x Objective = Total Magnification

Question 22

Why do you put the cover slip on a slide at an angle?

Answer 22

So that you don’t get any air bubbles.

Question 23

Why is stain sometimes used when making slides?

Answer 23

So that you can see the picture and nucleus more clearly.

Question 24

This is the complex network of membranes in the cytoplasm that is continuous with the nuclear membrane at several points, which help transport substances throughout the cell.

Answer 36

Yes - Pumps - Endosytosis - Exosytosis

Question 37

What is the difference between hypertonic, hypotonic, and isotonic solutions relative to the internal cellular enviorment?

Answer 37

Hypertonic- High Solute compared to the cell Hypotonic - Low solute concentration compared to the cell Isotonic - Contains same solute concentration as the cell

Question 38

What is dynamic equilibrium? When does it happen?

Answer 38

A reversible reaction. When something needs to be changed.

Question 39

Describe what happens to a cell when placed in hypertonic, hypotonic, and isotonic solutions.

Answer 39

They are all bathed in fluid. How the fluid compares to the internal cellular environment, may cause water to move in or out of the cell.

Question 40

What are the three main differences between plant and animal cells?

Answer 40

Besides the size there is also the chloroplasts, cell wall, and vacuoles.
