Lab 2 Cell Structure and Function
bio 201 l_lab2
Pre-Lab Questions:
“1. Identify the major similarities and differences between prokaryotic and eukaryotic cells. “
“2. Where is the DNA housed in a prokaryotic cell? Where is it housed in a eukaryotic cell? “
“3. Name three structures which provide support and protection in a eukaryotic cell. “
Experiment 1: Cell Structure and Function
Post-Lab Questions
“1. Label each of the arrows in the following slide images: “ A-, B-
“2. What is the difference between the rough and smooth endoplasmic reticulum? “
T
“3. Would an animal cell be able to survive without a mitochondria? Why or why not? “
“4. 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.
- How did the surface area affect diffusion to the center of the cell? What about volume?
What about the surface area-to-volume ratio?
“3. How does this experiment demonstrate the need for larger cells to divide? “
