differences between prokaryotic and eukaryotic organisms
Module 02 Homework Assignment
- Use the information presented in the module folder along with your readings from the textbook to answer the following questions.
- Describe four (4) important differences between prokaryotic and eukaryotic organisms:
- Prokaryotic cells lack a nucleus surrounded by a complex nuclear membrane and have a single circular chromosome located in a nucleoid whereas eukaryotic cells have a nucleus surrounded by a complex nuclear membrane that contains multiple, rod-shaped chromosomes.
- Prokaryotic cells are classified within the domains Archaea and Bacteria and eukaryotic cells are classified within the domain Eukarya.
- Eukaryotic cells are generally larger than prokaryotic cells.
- In eukaryotic cells, Lysosomes/peroxisomes, mitochondria, microtubules are present, whereas they are absent in prokaryotic cells.
differences between prokaryotic and eukaryotic organisms
- Briefly describe the function of the following organelles:
- a) Plasma membrane – control transport of molecules in and out of the cell.
- b) Glycocalyx – allows cells to stick to surfaces, assisting in the formation of biofilms.
- c) Cell wall – it covers the cell membrane, and protects the cells from changes in osmotic pressure.
- d) Nucleus – controls all activities of the cell and plays a big part in reproduction and heredity.
- e) Endoplasmic reticulum – serves as the fusion, folding, alteration and transport of proteins.

- f) Golgi apparatus – processes and sorts proteins from the endoplasmic reticulum for transport to their destination.
- g) Lysosomes – breaks down numerous particles. i.e. food, damaged organelles or cellular debris, microorganisms
- h) Ribosomes – with high speed and accuracy, it synthesizes proteins
- i) Peroxisomes – produces hydrogen peroxide and plays a role in lipid biosynthesis
- j) Mitochondria – similar to a digestive system in which it takes nutrients, grinds them down, and makes molecules for the cell.
- k) Chloroplasts – makes the sugars that then feeds the cells machinery.
- What is a biofilm? Discuss the advantages and disadvantages of biofilms:
- Briefly describe the process of aerobic cellular respiration. How does this process differ from anaerobic cellular respiration? How are these processes similar?
- Briefly describe the difference between eukaryotic cell division and prokaryotic cell division. Be sure to include the name of the processes that each uses to replicate:
