What controls the movement of substances in and out of a cell?

Why can animal cells burst where plant cells can't?
Plant cells have a cell wall which supports the cell and prevents it from bursting when the cell is full of water (turgid).
They have chloroplasts.
They have a permanent vacuole which is filled with cell sap to keep the cell turgid.
What is the function of chloroplasts?
They contain chlorophyll which absorbs light energy for photosynthesis.
They are filled with cell sap to keep the cell turgid.
