The cell is the basic unit of

life. All organisms are made

up of cells (or in some cases,a single cell). Most cells are

very small; most are invisible

without using a microscope.

Cells are covered by a cell

membrane and come in manydifferent shapes. The

contents of a cell are called

the protoplasm.

Centrioles - organize the assembly of

microtubules during cell division.

Cytoplasm- gel-like substance within

the cell.Endoplasmic Reticulum- extensive

network of membranes composed of

both regions with ribosome's.

Golgi Complex - responsible for

manufacturing, storing and shipping

certain cellular products.

Lysosomes - sacs of enzymes thatdigest cellular macromolecules such

as nucleic acids.

Microtubules - hollow rods that

function primarily to help support and

shape the cell.

Mitochondria - power producersand the sites of cellularrespiration.

Nucleus - membrane boundstructure that contains the cell'shereditary information.

Nucleolus - structure within thenucleus that helps in thesynthesis of ribosomes.

Nucleopore - tiny hole within thenuclear membrane that allowsnucleic acids and proteins tomove into and out of the nucleus.

Ribosomes - consisting of RNAand proteins, ribosomes areresponsible for protein assembly.

Comprising incorporating nutrition food inside the cell, the processing

thereof and the assimilation of substances useful for forming the cell and its

own material.

Depending on your nutrition, cells are autotrophic and heterotrophic cells.

Autotrophic cells make their own organic matter from inorganic matter of

the physical environment that surrounds it, using ell or chemical energy

contained in inorganic matter.

The animal cell differs from other eukaryotes, mainly of plant

cells which lack a cell wall and chloroplasts, and having

smaller vacuoles. Due to the absence of a rigid cell wall, the

animal cells may take a variety of shapes, and even a

phagocyte cell may in fact surround and engulf other

structures.
