Access Code (located on the lid of your lab kit): AC1TI
Pre-Lab Questions
1. Identify three major similarities and differences between prokaryotic and eukaryotic
cells. Prokaryotic does not have a nucleus, whereas eukaryotic does.
Prokaryotic has a single loop DNA structure. Eukaryotic has a complex linear DNA structure.
Prokaryotic cells do not have mitochondria present. Eukaryotic cell have mitochondria.
2. Where is the DNA housed in a prokaryotic cell? Where is it housed in a eukaryotic
cell? DNA is carried on a signle loop that is attached to the cell member in a prokaryotic
cell. In a Eukaryotic cell DNA is housed in the nucleus.
3. Identify three structures which provide support and protection in a eukaryotic cell.
The plasma membrane separates the cell from the outside environment. The cell wall, when
present provides shape and protects from injuries. The cytoskeleton provides the correct shape
and anchors the cellular organelles.

Structure Identity
A Chromosomes
B Nucleus
C Cytoplasm
D Cell Wall
2. What is the difference between the rough and smooth endoplasmic reticulum?
The rough endoplasmic contain Ribosomes. Smooth endoplasmic reticulum are smooth because
they lack Ribosomes.
3. Would an animal cell be able to survive without mitochondria? Why or why
not? Most likely not as the mitochondria provides energy.
4. 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?
I would assume I am looking at a Prokaryotes cell.
5. Hypothesize why parts of a plant, such as the leaves, are green, but other parts, such as the roots,
