Cells are the basic units of all
living things.
Cells are made of parts, called
organelles, that each do their own job for
the cell.
The nucleus is the largest organelle that stores the chromatin
(genetic material) and controls all the cells
activities.
What about your topic might be the
nucleus?
The cell membrane is like a security guard. No one gets in or out of the cell without its permission
and it is “selective” about what it lets in and out.
What about your topic might be the cell membrane?
The cell wall is found only in plant cells, is non-living, and supports and protects the cell.
What about your topic might be the
cell wall?
The mitochondria are considered the powerhouse of
the cell because they break down food (glucose) and
release energy! This is known as cellular respiration.
What about your topic might be the
mitochondria?
The vacuole is a temporary storage area in the cell that holds water, food,
and waste.
Vacuoles are small and numerous in animal cells but there is only one really big one in
plant cells.
What about your topic might be the
vacuole?
Cytoplasm is the “stuff” that supports all the
organelles and allows them to get their jobs done so the cell can continue living. It is vital to the cell and is mostly
made of water.
What about your topic might be the
cytoplasm?
Chloroplasts are naturally GREEN and make all the food for
plants only. This food is in the form of a
sugar called glucose.
Think of the chloroplasts as the “food makers” or
providers and the mitochondria as the
energy releasers or food “breakerdowners”
What about your topic might be the
chloroplast?
The endoplasmic reticulum is like a super
small and intricate highway system in the
cell because it move things around.
Often referred to as ER…it can be smooth (without ribosomes) or
rough (with ribosomes).
What about your topic might be the
ER?
The Golgi body or Golgi apparatus is often compared to
a post office. This is because materials made by the cell (i.e.
proteins, lipids, etc.) are packaged, labeled, and shipped
off to other areas of the cell from here.
What about your topic might be the
Golgi body?
Lysosomes are like the custodians of the cell. They will seek out and
destroy any and all waste inside the cell.
What about your topic might be the
lysosome?
The nucleolus hides out inside the nucleus with
the chromatin and manufacture all the
ribosomes. It does NOT contain the DNA.
What about your topic might be the
nucleolus?
Without the ribosomes, no cell would be able to make any
proteins. Of course, the nucleus tells the ribosomes
which ones to make…but they are very important nonetheless.
Proteins are vital to every living thing and are actually responsible
for how an organism looks, behaves, performs their life
processes, etc. The code for making proteins is housed in the DNA of every cell and basically tells that
cell what kind of cell to be.
What about your topic might be the ribosomes? How
about your protein?
How are plant and animal cells alike? How
are they different?
• LOTS OF SMALL VACUOLES
• IRREGULAR SHAPE
• CHLOROPLASTS IN GREEN CELLS
• ONE LARGE VACUOLE
• CELL WALL• RECTANGULAR
SHAPE
• NUCLEUS• CYTOPLASM
• CELL MEMBRANE• MITOCHONDRIA
• VACUOLES
Two other types of organisms you
should be familiar with now are…
Bacteria…organisms that reproduce rapidly, are
prokaryotic, can cause disease but can also be very helpful, come in rod, sphere, or spiral
shapes and can often be treated with antibiotics.
Viruses…neither alive nor dead, they can’t reproduce by themselves (parasitic), come in several geometric
shapes, and can not be treated with antibiotics.
