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

Fill in the blank: The rigid layer outside the plant cell membrane is the , made primarily of cellulose .

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.

What is the difference between Rough ER and Smooth ER? A: Rough ER has ribosomes and makes proteins; Smooth ER makes lipids and detoxifies.
