If a red blood cell and a plant cell were placed in seawater, what would happen to the two types of cells?

Both cells would lose water, the red blood cell would shrivel and the plant plasma membrane would pull away from the cell wall.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
