Transport across plasma membrane, what does it mean, how does it occur and how do we wrap our heads around this process?

Up until this point, my general understanding of transport across plasma membranes is that it is the process of transporting molecules across the plasma membrane, depending on the type of molecule we are transporting will depend on the way it is transported. There are 2 main transport processes which include:

Active Transport:

- Which requires energy and moves against their concentration gradient

Passive transport:

- Which requires no energy and moves down the concentration gradient

I cannot seem to grasp this concept no matter how much research and reading and looking at pictures and videos I do.
