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.
Basically it controls everything that happens inside the cell, it's like a boss of the cell. People also call it the brain of the cell. But, the nucleus does not control everything. There is one part the nucleus cannot control, it is the cell membrane. The cell membrane controls what gets in or out of the cell.
