Both, animal and plant cells have a cell membrane. It is semi permeable. This means it only lets certain things in and certain things out. For instance, oxygen or H20 ( water ) need to go in to a cell. The cell membrane allows these to go in as they are needed and they are the right "size". But through osmosis( Google it if you are unsure what it is ) water may move out of a cell. To answer your question substances travel in and out of cells.
