V. Brief essay questions: Please write a concise and succinct response to each one of the following questions; be sure to mark your answers with the correct essay number. I am looking for clarity and detail which reflects your knowledge of the subject. Always include appropriate examples, if warranted.
2. You scoop up a water sample from a local pond nearby, because you are curious about the possible microbes that might live there. After looking at several slides that held drops of the sample, you noticed two different kinds of cells: One kind was very small and had no separate internal structures; the other kind was much larger, and it contained several kinds of internal structures that were physically different from each other. Please name each cell and briefly describe their overall similarities and differences.
Explanation / Answer
There are two types of cells
1. Prokaryotic cell:- Very smal and no seprate internal structure.
2. Eukaryotic cell:- Larger and contained several kinds of internal structure that are physically seprated from each other
SIMILARITIES:
1. They both have DNA as their genetic material.
2. They are both membrane bound.
3. They both have ribosomes .
4. They have similar basic metabolism .
5. They are both amazingly diverse in forms.
DIFERENCES:
1. eukaryotes have a nucleus, while prokaryotes do not
2. eukaryotes have membrane-bound organelles, while prokaryotes do not. The organelles of eukaryotes allow them to exhibit much higher levels of intracellular division of labor than is possible in prokaryotic cells.
3. Eukaryotic cells are, on average, ten times the size of prokaryotic cells.
4. The DNA of eukaryotes is much more complex and therefore much more extnsive than the DNA of prokaryotes.
5. Prokaryotes have a cell wall composed of peptidoglycan, a single large polymer of amino acids and sugar . Many types of eukaryotic cells also have cell walls, but none made of peptidoglycan.
6. The DNA of prokaryotes floats freely around the cell; the DNA of eukaryotes is held within its nucleus and associated with histones (proteins)
7. Eukaryotes undergo mitosis; prokaryotes divide by binary fission (simple cell division)
