Q. A student examined a particular plant cell through its various stages of growth. After making various measurements, he realised that the increase in cell size was largely due to enlargement of the central vacuole rather than an increase in the amount of cytoplasm. Why might this be an advantageous strategy for the cell?​

1. Enlarging the vacuole would make it unnecessary for the cell wall to stretch.​
2. Enlarging the cytoplasm would make the cell less turgid.​
3. Enlarging the vacuole would minimise any lowering of the surface area - volume ratio of the cytoplasm.​
4. All of these​
