The main difference between active transport and facilitated diffusion is:
1. In active transport the molecules move from areas of high to areas of low concentration
2. In active transport, you need carrier proteins
3. In active transport, you need ATP to move molecules against a concentration gradient
4. In active transport, only water molecules move

The concentrations of ions is significantly higher in the vacuoles than in the cytoplasm. The reason for this is:
1. Facilitated diffusion of the ions by the tonoplast
2. Active transport of the ions by the tonoplast
3. Presence of porins for diffusion of the ions
4. Bulk transport across the tonoplast
