You selected the AAAS benchmark:
Every cell is covered by a membrane that controls what can enter and leave the cell. In all but quite primitive cells, a complex network of proteins provides organization and shape and, for animal cells, movement.

The cell
Cells have particular structures that underlie their functions. Every cell is surrounded by a membrane that separates it from the outside world. Inside the cell is a concentrated mixture of thousands of different molecules which form a variety of specialized structures that carry out such cell functions as energy production, transport of molecules, waste disposal, synthesis of new molecules, and the storage of genetic material.

In
this
activity,
learners
solidify
their
conceptualization
of
cells
by
building
a
model
of
a
cell
in
a
ziplock
bag.
The
three-dimensional
nature
of
cells
comes
to
life
as
learners
use
everyday
objects
to
represent
the
many
parts
of
a
cell.
In
addition,
learners
can
use
this
activity
to
develop
a
sense
of
scale,
calculating
how
big
a
human
would
be
if
the
ziplock
bag
cell
model
were
really
the
size
...

The Game of Life: Stem Cell Edition
|
|
In this activity, learners play a game that models what happens as stem cells differentiate into different cell types. As learners play, they'll discover that a wide variety of cells can arise as different "cell fate decisions" are made along a stem cell's developmental path.
