a student is asked to draw four cells.
which drawing is a representation of a prokaryotic cell?
four cell images (a, b, c, d)

dna\t□\t□
nucleus\t□\t□
ribosome\t□\t□

Explanation:

Part 1: Which drawing is a prokaryotic cell?

Prokaryotic cells (like bacteria) lack a nucleus and membrane - bound organelles. Option A looks like a plant cell (has a large vacuole, cell wall, and likely chloroplasts, eukaryotic). Option B looks like an animal cell (eukaryotic, has a nucleus). Option C is a bacterial cell (prokaryotic, no nucleus, has a cell wall, flagella, and circular DNA). Option D looks like a plant cell (eukaryotic, has a nucleus, cell wall, vacuole). So the prokaryotic cell is option C.

Answer:

C. The drawing of the bacterial - like cell (with no nucleus, cell wall, flagella, and circular DNA - like structure inside)

Part 2: Filling the table (Cell Structures: Present in Animal Cells, Present in Bacteria Cells)

Cell wall:

• Animal cells: Animal cells do not have a cell wall (they have a cell membrane). So the box for “Present in Animal Cells” is unchecked, and the box for “Present in Bacteria Cells” is checked (bacteria have a cell wall).

DNA:

• Animal cells: Animal cells have DNA (in the nucleus and mitochondria). So the box for “Present in Animal Cells” is checked.
• Bacteria cells: Bacteria have circular DNA (nucleoid region). So the box for “Present in Bacteria Cells” is checked.

Nucleus:

• Animal cells: Animal cells have a nucleus (eukaryotic). So the box for “Present in Animal Cells” is checked.
• Bacteria cells: Bacteria are prokaryotic and do not have a nucleus. So the box for “Present in Bacteria Cells” is unchecked.

Ribosome:

• Animal cells: Animal cells have ribosomes (for protein synthesis). So the box for “Present in Animal Cells” is checked.
• Bacteria cells: Bacteria have ribosomes (70S ribosomes). So the box for “Present in Bacteria Cells” is checked.
