GIVING BRAINLIEST 15 POINTS Based on the diagram, describe how the structure of these organelles controls movement across the membranes.

(Cells are the basic units of life.) Cells can exist by themselves, like bacteria, or as part of a larger organism, like our cells. As opposed to Viruses which are non-living infectious particles, much smaller than a cell, and need a living host to reproduce.

Explanation:

Carrier proteins hold binding sites that the necessary substances attach to so they can be moved across the membrane. Larger molecules such as sugars, some ions, other highly charged materials, amino acids and starches cannot drift across the membranes without aid.
