Cells
Plant and Animal
Cells are the Starting
Point

All living organisms on Earth are divided in pieces called
cells. There are smaller pieces to cells that include proteins
and organelles. There are also larger pieces called tissues
and systems. Cells are small compartments that hold all of
the biological equipment necessary to keep an organism
alive and successful on Earth.

Cell – the basic unit of structure and
function of living things
Organelle – structures that make up a
cell
Cell Theory – all living things are made
of cells that came from other living cells
Selectively Permeable – only allows
certain materials to pass through


Elements are found on the Periodic
Table arranged according to increasing
atomic number
Elements are represented by a chemical
symbol (one capital letter or a capital
letter with one or two lower case letters)
Elements are made up of atoms
