Please answer the following three essay questions.

  1. All living cells, both prokaryotic and eukaryotic, have thefollowing cell structures: plasma membrane, cytosol, ribosomes, andat least one chromosome. Choose any one of these. Describe itsbasic structure (including molecular composition) as well as thefunction. Explain why a cell could not exist without thefunction(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 anyone of the following comparison questions. Be sure to compare bothmolecular (physical) structure and function in each answer.
    1. Compare the nucleoid area (prokaryotic) to a nucleus(eukaryotic)? How do they differ; how are they similar?
    2. Compare the bacterial flagellum (prokaryotic) to an animal cellflagellum (eukaryotic)? How do they differ; how are theysimilar?
    3. Compare a bacterial cell wall (prokaryotic) to a plant cellwall (eukaryotic)? How do they differ; how are they similar?
  3. Eukaryotic cells (in plants, animals, fungi, and algae) arebigger than prokaryotic (bacterial) cells. This bigger size allowseukaryotic cells to have more structural complexity.

Choose any one of the following eukaryotic cell structures for ashort essay:

  • Mitochondrion
  • Cytoskeleton
  • Golgi apparatus
  • Endoplasmic reticulum
  • Lysosome
  • Chloroplast (found only in photosynthetic cells)

In your answer, describe its basic structure (includingmolecular composition) as well as the function. Why is the functionimportant to keeping the cell alive?
Provide references in APA format. This includes a reference listand in-text citations for references used throughout theassignment.
