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.
Allows oxygen and nutrients to enter the cell. Allows waste products to pass out of the cell. ---------------------------------------------------. Each organelle inside a eukaryotic cell (plant and animal) is also surrounded by a membrane to control what enters and leaves its organelle.
