Talk about plant vacuoles.

Lysosomes are absent in plants since no endocytosis or phagocytosis are possible in cell wall, but vacuoles are present. Formed from many small vacuoles (meristems) that fuse together, bounded by a membrane called tonoplast with many transport enzymes, which makes ion concentration in vacuole higher than that of cytosol, and it is hypertonic (accepts water by osmosis and turgor pressure providing support to unwoody plant tissues, and helps in stretching and growth pH is acidic.
