Find out the incorrect statement
| 1. | Middle lamella is mainly made up of Ca-pectate |
| 2. | Cell wall is formed from inner side therefore secondary wall formed before primary wall |
| 3. | Middle lamella glues the different neighbouring cells together |
| 4. | Pits are present in secondary wall |
Correct statement in relation to vacuoles is
| 1. | It is a triple membrane bound space found in cytoplasm containing sap |
| 2. | It can occupy 90% of cell volume in plants |
| 3. | Its membrane allows transport of materials along the concentration gradient only |
| 4. | Concentration of ions is significantly lesser in vacuole than cytoplasm |
