3. We are made of TRILLIONS of cells!
A cell is the basic
unit of structure
and function of all
living things.
We are made of TRILLIONS
of cells!
All humans, animals, plants,
and bacteria are made of
cells!

4. A cell has many different parts that help it
function. These are called
organelles.
Organelles have structure
(how it’s built)
and a function (what it does).

5. The cell membrane is the outer layer of the cell
that works as a screen
allowing nutrients, water,
and oxygen in the cell while
keeping harmful
substances out.

6. The cytoplasm is a gel-like fluid that holds all
organelles allowing them
to move and function
properly.

7. The “mighty” mitochondria is considered the “powerhouse” of the cell
because it helps the cell break
down nutrients creating
energy for the cell.

8. Golgi bodies function as a “post office” for the cell
because it helps package
up proteins and nutrients
to ship off to other parts
of the cell.

9. The nucleus is considered the “brain” of the cell
because it controls what each
cell does and becomes.
DNA is located in the nucleus of
every cell.

10. The nucleolus is part of the nucleus. Ribosomes are created here.

11. The endoplasmic reticulum serves as a transport system
or “highway” for
proteins and other organelles
to move about the cell.
There is rough and smooth
endoplasmic reticulum. The
rough ER is studded with
ribosomes, the smooth
ER is not.

12. little protein factories, producing proteins to aid in cell function.
Ribosomes function as
little protein factories,
producing proteins to aid in
cell function.

13. Lysosomes can be compared to a “recycling center.” They
break down nutrients,
molecules, and waste materials
for different purposes.

14. Vacuoles are the storage tank for the cells storing energy, food,
water, etc.
Plant cell have one large
vacuole while animal cells have
multiple small vacuoles.

15. Chloroplasts are only found in plant cells. Chloroplasts take
in sunlight and transforms it
to energy for the plant
(photosynthesis occurs here).
Chloroplasts are the reason
why leaves and other plants
are green in color.

16. A cell wall is only found in a plant cell & provides
extra support & protection
for the plant cell.
