__﻿13.1- Biomolecules are Produced and Utilized in **Cells**cell-__ the fundemental unit of almost all organisms. Most cells are so small that only with a microscope are they visible individually. An example of such is that, about ten average-sized human cells could fit within the period at the end of this very sentence. __plasma membrane-__ this membrane acts not only as a boundary but it allows molecules to pass into and out of the cell and provides sites where important chemical reactions occur. In animal cells the outermost part of the cell is the plasma membrane, but with plant cells there is an extra barrier between the cell and the outside world. __cell wall-__ protects the cell and gives them structure and bounds the cell membrane. __cell nucleus-__ this contains the genetic code of the cell. __cytoplasm-__ everything between the plasma memrane and the cell nucleus. __organelles-__ microstructures suspended in a viscous liquid, they work together in the synthesis, storage, and export of important biomolecules. Most of the biomolecules used within the cell are either lipids, carbs (carbohydrates), protiens, or nucleic acids. Most cells along with these essentials need small amounts of both minerals and vitamins to function properly.
