Cell functions, like osmosis and
osmosis,
diffusion, become limited when a cell reaches
diffusion
a certain size; this influences the development
of more cells instead of bigger cells. Pg. 297
Cells reproduce by making copies of
cell cycle
themselves. Pg. 297
Cell division is needed for the growth of plants
and animals; repeated cell division eventually
becomes tissue. Pg. 298
Cell division also occurs in places cells that are
worn out or damaged (example skin). Pg. 298
The cell cycle is similar in all eukaryotes,
parent cell
although some parts of the cycle vary in
daughter cell
different organisms. All cycles have the
parent cell reproducing identical daughter
cells with identical genetic info. Pg. 298
The cell cycle starts when a new cell is formed
and continues until the cell is divided into two;
then each newly produced cell begins the cycle
again. Without the genetic info, organelles in
the cytoplasm and the cell membrane the cell
will be incomplete and not survive. Pg. 298
Most of the cell’s life is spent in interphase,
interphase
where the cell grows and performs intended chromosomes,
functions and genetic material is organized
DNA synthesis
into chromosomes. p. 299
Mitosis is the distribution of genetic
mitosis
information to daughter cells. Pg. 299
A few differences occur in mitosis between
centrioles, cell
plants and animals. Pg. 299 Animals have
plates
centrioles, plants have cell plates for cell walls.

Pg. 299
Cells of multicellular organisms contain the differentiation
same genetic material, but produce cells with
different functions (about 200 different types).
Pg. 299
Differences in cells result from the differences
in how they use the genetic information they
have. Pg. 299
As cells become specialized, they take on
distinct shapes and become more distinctive;
some cells divide often, while others almost
never divide (nerve cells). Pg. 299
