Q

is the envelope of the cell which gives shape, and serves as a covering and protective agent of the cell. It is a semi-permeable membrane that controls the molecules that may go into and out of the cell. In addition to the cell membrane, plants cell have cell wall that gives support and strength.

Q

which is considered as the “circulatory system of the cell”, which is of two(2) types, these are the rough ER (rER) and smooth ER (sER). The rough ER is lined with ribosomes, so that it is for the distribution of proteins, while the smooth ER is for the transportation of other materials, such as carbohydrates and lipids.
