What is the difference between Rough and Smooth ER?

• Rough ER is involved in detoxification; Smooth ER is involved in protein synthesis.
• Rough ER has a smooth surface; Smooth ER has a rough surface.
• Rough ER synthesizes carbohydrates; Smooth ER synthesizes nucleic acids.
• Rough ER has ribosomes and synthesizes proteins; Smooth ER lacks ribosomes and synthesizes lipids.

Why do cells have to be small?

• Cells are small to increase their surface area for photosynthesis.
• Smaller cells can store more genetic material than larger cells.
• Cells need to be small to maintain a higher temperature.
• Cells have to be small to ensure efficient nutrient uptake and waste removal.

What four structures are common in all cells?

• Cell wall, chloroplasts, mitochondria, vacuoles
• Cell membrane, Cytoplasm, Ribosomes, Cytoskeleton

• Nucleus, endoplasmic reticulum, Golgi apparatus, lysosomes
• Cytoskeleton, peroxisomes, centrioles, plasmids

What is the difference between a prokaryotic and eukaryotic cell?

• Prokaryotic cells lack a nucleus and organelles; eukaryotic cells have a nucleus and organelles.
• Prokaryotic cells have a complex structure with multiple nuclei.
• Prokaryotic cells are larger than eukaryotic cells.
• Eukaryotic cells lack a nucleus but have organelles.

Why do mitochondria and chloroplasts have their own DNA?

• Mitochondria and chloroplasts are created by the nucleus of the cell.
• They have their own DNA to produce energy more efficiently.
• Mitochondria and chloroplasts have their own DNA due to their evolutionary origin from engulfed prokaryotes.
• Their DNA is inherited from the parent organism.
