Statement 1: In plants, the tonoplast facilitates the transport of a number of ions and other materials against concentration gradients into the vacuole. Statement 2: In amoeba, the contractile vacuole is important for osmoregulation and excretion.

Step-by-step solution

In plants, the tonoplast facilitates the transport of a number of ions and other materials against concentration gradients into the vacuole; hence their concentration is significantly higher in the vacuole than in the cytoplasm. In amoeba, the contractile vacuole is important for osmoregulation and excretion. In many cells, as in protists, food vacuoles are formed by engulfing other food particles.
