Question

which structures are found in each cell type? complete the table.
prokaryotic cells eukaryotic cells
linear chromosomes
smooth endoplasmic reticulum
continuous loop of chromosomal dna
membrane - bound organelles
submit

Explanation:

• Linear chromosomes: Eukaryotic cells have linear chromosomes within a nucleus. Prokaryotic cells have circular DNA (not linear chromosomes).
• Smooth endoplasmic reticulum: It is a membrane - bound organelle. Prokaryotic cells lack membrane - bound organelles; eukaryotic cells have them, including the smooth ER.
• Continuous loop of chromosomal DNA: Prokaryotic cells typically have a single circular chromosome (continuous loop). Eukaryotic chromosomes are linear.
• Membrane - bound organelles: A defining feature of eukaryotic cells. Prokaryotic cells (like bacteria) lack these complex, membrane - enclosed structures.

Answer:

• Linear chromosomes: Prokaryotic cells (no), Eukaryotic cells (yes)
• Smooth endoplasmic reticulum: Prokaryotic cells (no), Eukaryotic cells (yes)
• Continuous loop of chromosomal DNA: Prokaryotic cells (yes), Eukaryotic cells (no)
• Membrane - bound organelles: Prokaryotic cells (no), Eukaryotic cells (yes)
