Why do mitochondria have folded inner membranes (cristae)? A: Increases surface area for chemical reactions that produce ATP (cellular respiration).

Which structure is found ONLY in animal cells? ✅ (rare in plants), Centrioles (for cell division) Section 7-2 Eukaryotic Cell Structure Answer Key Fixed

What is the difference between Rough ER and Smooth ER? A: Rough ER has ribosomes and makes proteins; Smooth ER makes lipids and detoxifies. Why do mitochondria have folded inner membranes (cristae)

Why is the Golgi apparatus compared to a "post office"? A: It modifies, sorts, and packages proteins into vesicles for delivery inside or outside the cell. ✅ (rare in plants), Centrioles (for cell division)
