Lab 2 Cell Structure and Function BIO201L

Pre-Lab Questions:

  1. Identify the major similarities and differences between prokaryotic and eukaryotic cells.
  1. Where is the DNA housed in a prokaryotic cell? Where is it housed in a eukaryotic cell?
  1. Name three structures which provide support and protection in a eukaryotic cell.

Experiment 1: Cell Structure and Function

Post-Lab Questions

  1. What is the difference between the rough and smooth endoplasmic reticulum?
  1. Would an animal cell be able to survive without a mitochondria? Why or why not?
  1. What is the function of a lysosome?

Experiment 2: Exploring Cell Size

Record the cell radius and time to center of the cell in Table 2. Then, calculate the

surface area, volume, and surface area:volume ratio (equations provided below).

Table 2: Surface Area and Volume in Relation to Cell Size

Post-Lab Questions

  1. Create a graph of the time to the center of the cell as a function of the surface

area:volume ratio.

 

 

  1. How did the surface area affect diffusion to the center of the cell? What about

volume? What about the surface area-to-volume ratio?

  1. How does this experiment demonstrate the need for larger cells to divide?

2. What is the difference between the rough and smooth endoplasmic reticulum?

  1. Would an animal cell be able to survive without mitochondria? Why or why not?
  2. What could you determine about a specimen if you observed a slide image showing the specimen with a cell wall, but no nucleus or mitochondria?
  3. Hypothesize why parts of a plant, such as the leaves, are green, but other parts, such as the roots, are not. Use scientific reasoning to support your hypothesis. Lab 2 Cell Structure and Function BIO101L

Experiment 2: Create a Cell

Post-Lab Questions

  1. What cell structures did you place in the plant cell that you did not place in the animal cell?
  2. Is there any difference in the structure of the two cells?
  3. What structures do cells have for support in organisms that lack cell walls?
  4. How are organelles in a cell like organs in a human body?
  5. How does the structure of a cell suggest its function? List three examples.
  6. In the table below, list the items you used to represent the various organelles in your ANIMAL cell. Provide a brief rationale explaining why you selected each item.s Code (located on the lid of your lab kit): Click here to enter text.
