Virtual Lab Report: Part I
Due by: 11:59 PM PST on the second Saturday of class
Virtual Lab 1: Virtual Microscopy
A. Estimate the size (length and width) of these microscopic objects in micrometers (microns):
1. An E. Coli cell. 3 x 0.6 um =1.8 um
2 A mitochondrion. 4 x 0.8 um = 3.2 um
3. A Red blood cell. 8 um
4. A virus. _Hepatitis 45 nm = .045 um
5. A water molecule. 275 pm =.275 um
B.
1 Describe three differences between prokaryotic and eukaryotic cells.
Prokaryotic don’t have a nucleus and their cell type is unicellular. They do not have a true membrane bound nucleus and they have loop DNA. They are rod shaped, spherical and spiral and they divide by binary fission. They are smaller in size as well.
Eukaryotic have tangled DNA and they have a nucleus. They have a multicellular cell type and they have a true membrane bound nucleus and they depend on oxygen for their metabolism. They are larger in size.

2. Describe three differences and three similarities between plant and animal cells.
Three similarities: Both have a cytoplasm, ribosomes, mitochondria and a nucleus.
Three differences: The plant cell has a cell wall and the animal cell does not.
The animal cell is round and the plant cell is rectangular.
The plant cell has plastids and the animal cell does not.

C. Form a hypothesis
1. Hypothesize about how you might be able to sort a mixed population of cells into prokaryotes and eukaryotes. Try to be practical, build on your understanding of the differences between the two cell classes. My best idea would be to sort them based on size since the eukaryote cells are smaller in size and the prokaryote cells are larger in size and shape. Another way
