Biology Cell Report

There are many parts of a cell, they all have specific duties, and are all
needed to continue the life of the cell.  Some cells exist as single-celled
organisms that perform all of the organism's metabolism within a single cell.
Such single-celled organisms are called unicellular.  Other organisms are
made up of many cells, with their cells specialized to perform distinct
metabolic functions.  One cell within an organism may be adapted for movement,
while another cell carries out digestion. The individual cells no longer
carry out all life functions, but rather depend on each other.  Many-celled
organisms are called multicellular. When a group of cells function together to
perform an activity, they form a tissue.  The cells of a human are organized
into tissues such as muscle and nerve tissues.  Plant tissues include those
of the stem and root.  Many cells in tissues are linked to each other at
contact sites called cell junctions.  Cell junctions help maintain differences
in the internal environment between adjacent cells, help anchor cells together,
and allow cells to communicate with one another by passing small molecules from
one cell to another. Groups of two or more tissues that function together
make up organs.  An organ system is a group of organs that work together to
carry out major life functions.

Boundaries and Control:

Plasma Membrane - The plasma membrane is sometimes called the cell membrane, or
the cellular membrane.  It is the outermost part of the animal cell, and it's
purpose is to enclose the cell, and change shape if needed.  The cell membrane
is capable of allowing materials to enter and exit the cell.  Oxygen and
nutrients enter, and waste products such as excess water leave.  The plasma
membrane helps maintain a chemical balance within the cell.

Cell wall - The cell wall is an added boundary to the cell.  It is relatively
inflexible, and surrounds the plasma membrane.  The cell wall is much thinker
than the plasma membrane and is made of different substances in different
organisms.  The cells of plants, fungi, almost all bacteria, and some protists
have cell walls.  Animal cells have no cell walls.  Plant cells contain
cellulose molecules, which form fibers.  This fibrous cellulose of plants
provides the bulk of the fiber in our diets.  Chitin, a nitrogen-containing
polysaccharid...
