3. The cell membrane is the
phospholipid bilayer
surrounding the cell. It
contains embedded
proteins that help it have
its selectively permeable
membrane to substances
on either side of it.
Cell Membrane (Magnetic blocks)
4. The nucleus is one of the
defining organelles of a
eukaryotic cell. It helps
control everything in the
cell. It also contains the
DNA, which is the stored
genetic instructions for
each cell. The nucleus is
widely known as the
control center of the cell.
Nucleus and DNA Material
(Marble is DNA, paper is Nucleus)
5. The mitochondria is
known as the power
plant of the cell. They
help carry out critical
steps that involve
extracting energy from
food and the converting
of that energy into a
useful form.
Mitochondria (Shelled Walnuts)
6. The cytoplasm is the
gelatinous, aqueous
interior of all cells. It
contains all of the cells
organelles, including the
nucleus.
Cytoplasm (Towel that was the
background of the cell)
7. The Golgi is known as
the packaging plant of
the cell. It receives newly
synthesized proteins
from the endoplasmic
reticulum and processes
and packages them for
transport in small
membrane vesicles.
Golgi Apparatus (Mini Wheats)
8. The ribosomes are
cellular machinery that
help to assemble
proteins during the
process of translation. It
helps to synthesize the
proteins that are so
crucial to the function of
the cell.
Ribosomes (Black pepper)
9. The ER is a plumbing
like system used for the
production of new
proteins. The rough ER
looks rough because it is
lined with ribosomes
which help it to make
proteins. The smooth ER
is an important site of
lipid production.
Rough and Smooth Endoplasmic
Reticulum (Red is rough ER, blue is
smooth ER)
10. Lysosomes are known as
recycling centers in a
cell. They are full of
digestive enzymes that
help break down worn
out cell parts so that they
can be used to build new
ones.
Lysosomes (Peanuts)
11. The vacuoles of the cell
are membrane bound
vesicles found in the
cytoplasm of the cell.
The functions of a
vacuole include
intracellular secretion,
excretion, and storage.
