These elements exist in the form of molecules and organelles â picture them as the tools, appliances, and inner rooms of the cell. Major classes of intracellular organic molecules include nucleic acids, proteins, carbohydrates, and lipids, all of which are essential to the cell's functions. Nucleic acids are the molecules that contain and help express a cell's genetic code. There are two major classes of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope 10. Thin, flexible barrier around a cell; regulates what enters and leaves the cell 11. In cells, structure that contains the cell's genetic material (DNA) and controls the cell's activities 12.Organism whose cells contain nuclei 13. Cell organelle that stores materials such as water, salts, proteins, and carbohydrates 14.hin, flexible barrier around a cell; regulates what enters and leaves the cell 11.
