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.
The cell structure which controls the activities of the cell is the nucleus. The nucleus contains the genes which give the cell instructions. Other cell parts, such as mitocho â¦ ndria, have other functions. Mitochondria, for example, are where energy is released from food by the process of respiration.
