Various labs completed in class will be posted on this page.

Cell Structure & Function

Distinguish the sizes and shapes of different types of cells, tissues and cellular components.
  1. Examine slide with saliva on it under the microscope & draw.
  2. Stain the slide and examine for any differences.
  3. Examine 4 different slides with different tissues & draw.
  4. Answer questions.


From this lab, one can see the differences between different types of cells and tissues and the cellular components.

Movements Through Cell Membranes


To demonstrate some of the physical processes by which substances move through cell membranes.


1. Fill each petri dish half way with water (one with cold water, one with hot water, and the last with regular tap water) and place on top of white paper and milimeter ruler for about 3 minutes; wait for water to settle.
2. Place one crystal of potassium permanganate near center and measure radius every minute for 10 minutes.
3. To demonstrate osmosis, soak an egg in vinegar until the shell is dissolved.
4. Then dip the egg in corn syrup; wash off egg gently then weigh it every 15 minutes.
5. Record the measurements.
6. Fill bulb of thistle tube with molasses and secure with ruber band.
7. Connect the tube to the clamp of a ring stand and immerse in water.
8. Record any changes.


Substances move throughthe membrane by physical processes such as diffusion and osmosis.

  1. Describe the cell cycle
  2. Identify the stages in the life cycle of a particular cell
  3. Arrange into a correct sequence a set of models or drawings of cells in varoius stages of their life cycles
