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 nucleus, often thought as as the centre of a cell, contains all the genetic. information of a cell (the cells chromosomes), it controls the activities of the cell. Cytoplasm surrounds the nucleus within the cell walls. It is where reactions take place in the cell.The cell membrane controls the movement of chemicals in and out of the cell. The cell wall, which is made up of cellulose, strengthens the cell.Chloroplast contain chlorophyll, and are used in photosynthesis.t is where reactions take place in the cell.
