Question

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

Explanation:

• Membrane - bound organelles: Prokaryotic cells lack membrane - bound organelles (e.g., mitochondria, endoplasmic reticulum), while eukaryotic cells have them.
• Smooth endoplasmic reticulum: It is a membrane - bound organelle. As prokaryotes lack membrane - bound organelles, they don't have it. Eukaryotes do.
• Continuous loop of chromosomal DNA: Prokaryotic DNA is typically a single, circular (continuous loop) chromosome. Eukaryotic DNA is organized into linear chromosomes.
• Linear chromosomes: Eukaryotic cells have linear chromosomes within a nucleus. Prokaryotic cells have circular DNA (not linear chromosomes).

Answer:

• Membrane - bound organelles: 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)
• Linear chromosomes: Prokaryotic cells (no), Eukaryotic cells (yes)
