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 membrane promotes homeostasis by controlling what  substances are allowed to enter and leave the cell. This process is  called diffusion. It also helps to maintain â¦ homeostasis through  osmosis.he term homeostasis refers to maintaining a relatively stable internal environment inside of a multi-cell organism. Since the internal environment is the interstitial fluid that is around each and every cell, then homeostasis has more to do with what is outside of a cell than what is inside of it.
