Biology: Cell structure
All cells have three things in common,
no matter what type of cell they are.
The nucleus contains DNA or genetic
material. DNA dictates what the cell is
going to do and how it will do it. There
are two broad categories of cells. The
first category is eukaryotic cells. They
do n't have a nucleus or membrane-
enclosed organelles. The second
category is prokaryotic. The
mitochondrion is an organelle that is
the powerhouse for both animal and
plant cells. During a process called
cellular respiration , the mitochondria
make ATP molecules that provide the
energy for all of the cell 's activities.
Meanwhile, the cell maintains its shape
through a cytoskeleton.
