Answer:

number 3 is the central vacuole and its  large, membrane-bound organelles found in plant cells that act as a storage space for water and other molecules in the cell

Explanation:

Answer:

3. Vacuole

Explanation:

Plant vacuole is a membrane (tonoplast) bound space which contains sap, water, excretory products and other materials (which are not useful for plants).



  • It occupies 90% of the volume of the plant cell.

  • Tonoplast, in plants facilitates transport of ion into the vacuole (against the concentration gradient) which causes higher ionic concentration in vacuole than in the cytoplasm.

Some other points:-

  •  Amoeba have contractile vacuole for osmoregulation and excretory purposes.

  • Some protists develop food vacuoles by engulfing food particles.
