Therefore, as gravity affects all things equally, regardless of their mass in grams or kilograms, and because 1 m/s 2 = 100 cm/s 2, the surface gravity of Earth could be expressed in cgs units as 980.665 cm/s 2 and at base 10 logarithm (log g) as 2.992.
The cell wall is only in plants, and it gives the plants structure. The cell membrane controls the movement of substances entering and leaving the cell.
Vacuoles regulate the turgidity by regulating the amount of water inside the cell. cell has excessive water: vacuole absorbs the water and then diffuses it out of the cell. cell lacks water: water from the vacuole gets passed back into the cell thereby maintaining turgidity.
