Cells are of different types- Animal cells and Plant cells. The leaf epidermal cell is an example of plant cell and the visible components will be the <em>nucleus, mitochondria, chloroplasts, central vacuole and cell wall</em>.
Explanation:
The cell organelles present in plant cells are different from those in animal cells.<u> Human cheek cell is an animal cell</u>. The animal cells contain a cell membrane which is absent in plant cells. Chloroplasts are <em>absent</em> in animal cells since they do not perform photosynthesis. Mitochondria and Golgi complex are present in <u>both plant and animal cells</u>.
The Answer is ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds.
