Pre-Lab Questions:
1. Identify the major similarities and differences between prokaryotic and eukaryotic
cells. Similarities
Both eukaryotic and prokaryotic cells bears a lipid bilayer which is an arrangement of
phospholipids and proteins that acts as a selective barrier between the internal and external
environment of the cell.
Eukaryotic and prokaryotic cells bothuse deoxyribonucleic acid as the basis for their genetic
information.
Eukaryotic and prokaryotic cell require ribosomes to facilitate RNA translation and the
creation of protein which is very essential for their functioning.
Eukaryotic and prokaryotic cell both possess cytoplasm which facilitates biochemical
reactions in the cell.
Differences
Eukaryotic cells have a true nucleus bound by a double membrane while prokaryotic cell
have no nucleus.
Eukaryotic DNA linear and complexed with packing proteins called histones while
prokaryotic DNA is circular and is neither associated with histones.
Eukaryotic cells are ordinarily larger (10 – 100um) while prokaryotic cells are small (1 –
10um) Eukaryotic cells contain many membrane enclosed, large, complex organells in the
cytoplasm while prokaryotic cells do not contain these membrane bound organelles.
Eukaryotic cells undergo sexual reproduction while prokaryoticv cells under asexual
reproduction
2.Where is the DNA housed in a prokaryotic cell? Where is it housed in a eukaryotic
cell? In a prokaryotic cell, the DNA is housed in a the region called nucleiod . In
eukaryotic cll, the DNA is housed in the nucleus.
3. Name three structures which provide support and protection in a eukaryotic cell.
The structures which provide support and protection in a eukaryotic cell are cell membrane,
cell wall, and cytoskeleton
