Question
Please answer the following three essay questions.
1.All living cells, both prokaryotic and eukaryotic, have the following cell structures: plasma membrane, cytosol, ribosomes, and at least one chromosome. Choose any one of these. Describe its basic structure (including molecular composition) as well as the function. Explain why a cell could not exist without the function(s) performed by this cell structure.
2.Cells can be categorized as either prokaryotic or eukaryotic. Only bacterial cells are prokaryotic. For question two, answer any one of the following comparison questions. Be sure to compare both molecular (physical) structure and function in each answer.
a.Compare the nucleoid area (prokaryotic) to a nucleus (eukaryotic)? How do they differ; how are they similar?
b.Compare the bacterial flagellum (prokaryotic) to an animal cell flagellum (eukaryotic)? How do they differ; how are they similar?
c.Compare a bacterial cell wall (prokaryotic) to a plant cell wall (eukaryotic)? How do they differ; how are they similar?
3.Eukaryotic cells (in plants, animals, fungi, and algae) are bigger than prokaryotic (bacterial) cells. This bigger size allows eukaryotic cells to have more structural complexity.
Choose any one of the following eukaryotic cell structures for a short essay:
•Mitochondrion
•Cytoskeleton
•Golgi apparatus
•Endoplasmic reticulum
•Lysosome
•Chloroplast (found only in photosynthetic cells)
In your answer, describe its basic structure (including molecular composition) as well as the function. Why is the function important to keeping the cell alive?
Provide references in APA format. This includes a reference list and in-text citations for references used throughout the assignment.
Explanation / Answer
I'll help, but I will not do the entire set of essays. 1. Chromosome- (In my opinion easiest to write about) Chromosomes are largely composed of genetic material such as DNA or RNA. These are further composed of nucleotides attached to phosphate backbone and sugar in series. The chromosomes may also contain protein elements such as histones. This allows the genetic material to be organized. Chromosomes are essential because they are necessary to bind to messenger RNA during transcription in order to produce proteins during translation. The Chromosomes are also essential in recombination leading to evolution. Without chromosomes, there would be no genes expression the organism could neither function nor grow. 3. Mitochondrion are the power house of the cell and are believed the result of a earlier symbiosis between a bacteria and eukaryote. They are essential in produces ATP (adenosine triphosphates) which is the main source of energy in most cells. This generation of ATP is facilitated by its cristae and mitochondrial matrix.
