Answer to Question #343636 in Human Anatomy and Physiology for Laiba

Question

List the fundamental properties shared by all cells. Describe the importance of each of these properties.

Answer 1

ALIVE. Cells are generally the smallest unit of life. Individual cells can be removed from a plant or animal and grown (sometimes indefinitely) in culture, but this cannot generally be done with individual cell parts.

HIGHLY COMPLEX & Organized. The complexity means that the cell can perform intricate functions with a great deal of regulation and control. The organization of cells is visible at all levels; molecular, polymeric, complexes, organellar, and cellular. The organization is important for the function of cells.

GENETIC INFORMATION. All the info needed by the organism is packaged within the cell.

GROWTH & REPRODUCTION. Cells are capable of expanding their biomass and producing more cells.

ENERGY. Cells are able to use energy to perform their functions (Either by obtaining it directly from external sources or making it form other energy sources such as the sun).

METABOLISM. Cells are capable of performing chemical reactions that would not occur or would only occur slowly outside the cell.

MOVEMENT. All cells are able to move materials within their boundaries and some cells are able to move themselves.

RESPONSIVE. Cells will respond to internal and external stimuli in order to maintain a steady state or homeostasis.
