Question

bio 1.1.2 compare prokaryotic and eukaryotic cells in terms of their general structures (plasma membrane and genetic material) and degree of complexity.
how do you determine total power magnification of a light microscope? (choose one)
objective x objective b. ocular x objective c. ocular + objective
which reveal greater detail about eukaryotic and prokaryotic cell differences? (choose one)
scanning/electron transmission microscopes or light microscopes
infer which are more complex, prokaryotic cells or eukaryotic cells? (circle)
identify each cell as prokaryotic or eukaryotic

compare the structure of prokaryotic and eukaryotic cells. which of these organelles are found in each type of cell?
____ mitochondria __ nucleus ____ chloroplast
____ ribosomes __ dna/rna ____ plasmids
____ smaller cells ____ larger cells
______ genetic material enclosed in nuclear membrane

Explanation:

• For the first question, the total magnification of a light microscope is calculated by multiplying the magnification of the ocular lens (eyepiece) by the magnification of the objective lens.
• For the second question, scanning/electron transmission microscopes have a higher resolution than light microscopes, so they can reveal greater detail about cell differences.
• For the third question, eukaryotic cells are more complex than prokaryotic cells as they have membrane - bound organelles, a nucleus, etc.
• For the organelle comparison:
• Mitochondria: Eukaryotic cells.
• Nucleus: Eukaryotic cells.
• Chloroplast: Eukaryotic (plant) cells.
• Ribosomes: Both (prokaryotic and eukaryotic).
• DNA/RNA: Both.
• Plasmids: Prokaryotic (also some eukaryotes like yeast can have plasmids in a limited sense, but mainly prokaryotic).
• Smaller cells: Prokaryotic.
• Larger cells: Eukaryotic.
• Genetic material enclosed in nuclear membrane: Eukaryotic.

Answer:

• First question: b. Ocular x Objective.
• Second question: Scanning/electron transmission microscopes.
• Third question: Eukaryotic cells.
• Organelle comparison:
• Mitochondria: Eukaryotic.
• Nucleus: Eukaryotic.
• Chloroplast: Eukaryotic (plant).
• Ribosomes: Both.
• DNA/RNA: Both.
• Plasmids: Prokaryotic.
• Smaller cells: Prokaryotic.
• Larger cells: Eukaryotic.
• Genetic material enclosed in nuclear membrane: Eukaryotic.
