Movement - ANS Muscle cells can generate forces that produce motion. Muscles that are
attached to bones produce limb movements, whereas those muscles that enclose hollow tubes
or cavities move or empty contents when they contract (e.g., the colon).
Conductivity - ANS Conduction as a response to a stimulus is manifested by a wave of
excitation, an electrical potential that passes along the surface of the cell to reach its other
parts. Conductivity is the chief function of nerve cells.

, Metabolic Absorption - ANS All cells can take in and use nutrients and other substances from
their surroundings.
Secretion - ANS Certain cells, such as mucous gland cells, can synthesize new substances
from substances they absorb and then secrete the new substances to serve as needed
elsewhere.
Excretion - ANS All cells can rid themselves of waste products resulting from the metabolic
breakdown of nutrients. Membrane-bound sacs (lysosomes) within cells contain enzymes that
break down, or digest, large molecules, turning them into waste products that are released
from the cell.
Respiration - ANS Cells absorb oxygen, which is used to transform nutrients into energy in the
form of adenosine triphosphate (ATP). Cellular respiration, or oxidation, occurs in organelles
called mitochondria.
Reproduction - ANS Tissue growth occurs as cells enlarge and reproduce themselves. Even
without growth, tissue maintenance requires that new cells be produced to replace cells that
are lost normally through cellular death. Not all cells are capable of continuous division (see
Chapter 4).
Communication - ANS Communication is vital for cells to survive as a society of cells.
Appropriate communication allows the maintenance of a dynamic steady state.
Three Cellular Components of the Eukayrotic cell consists of - ANS outer membrane: which is
called the plasma membrane or plasmalemma.
A "fluid filling" called cytoplasm.
The "organs" of the cell called organelles(membrane bound intracellular)
among them the nucleus.
