Cell and developmental biology explains the structure, organization of the organelles they contain, their physiological properties, metabolic processes, Signaling pathways, life cycle and interactions with their environment. This is done both on a microscopic and molecular level as it encompasses prokaryotic cells and eukaryotic cells.
The study of the cell is done on a molecular level; however, most of the processes within the cell are made up of a mixture of small organic molecules, inorganic ions, hormones, and water. Approximately 75-85% of the cells volume is due to water making it an indispensable solvent because of its polarity and structure. These molecules within the cell, which operate as substrates, provide a suitable environment for the cell to carry out metabolic reactions and signaling.
