Question

Why many cell organelles contain folded or stacked membranes

Answer 1

The many folds result in more surface area for ribosomes to attach and thus allowing protein synthesis to occur at a more efficient rate.

Step-by-step explanation:

Answer 2

As a cell grows, its volume increases more quickly than its surface area. If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell's needs.These folds increase the surface area available for transport of materials into or out of the cell.
