1. What is the Cell Theory?
1. All organisms are made of one or more
cells.
2. The cell is the basic unit of all living
things.
3. All cells come from existing cells.
2. The first person to discover cells.
In 1665, he looked at cork ”little
cells” in a compound microscope he
invented.
Robert Hooke
3. 1st person to see bacteria on a
microscope. Looked at pond scum and
found “little animals” (protists) in a
microscope he built himself (1673).
Anton van Leeuwenhoek
4. “All plants have cells.” (1838)
(Cell Theory)
Matthias Schleiden
5. “All animals have cells.” (1839)
Theodor Schwann
6. “All cells form only from other
cells.” (1858)
Rudolf Virchow
7. What is smallest unit that can
perform all the processes
necessary for life?
Cells

statements is not part of the cell
theory?
a. Animals and plants share the same
kinds of cells.
b. All organisms are made up of one or
more cells.
c. The cell is the basic unit of all living

A
9. What part of the cell is
responsible for the production of
protein?
Ribosomes
10. The part of the cell that is
made of jellylike material outside
the cell nucleus in which the
organelles are located
Cytoplasm
11. The part of an animal cell surrounded by
a membrane containing digestive enzymes.
This is where the digestion of cell nutrients
takes place. This is the “garbage truck” of
the cell.
Lysosomes
12. A thick, rigid membrane that
surrounds a plant cell that
provides support and structure is
the ___________________.
Cell Wall
13. If you needed to identify a Plant
Cell from an Animal Cell, what will
you find in a Plant Cell that is not in
an Animal Cell?
Cell Wall and Chloroplast
14. What part of the cell is a web
of protein located in the cytoplasm
and keeps the cell membrane from
collapsing?
Cytoskeleton
15. If you needed to identify an
Animal Cell from a Plant Cell,
what will you find in a Animal Cell
that is not in a Plant Cell?
Lysosomes
16. What part of the cell forms
a barrier between the cell and
its environment?
Cell Membrane
17. A single-celled organism that
has no nucleus or membranebound organelles
Prokaryote
18. Organisms made up of cells
that have a nucleus and
membrane-bound organelles.
Eukaryotes
19. The process by which plants,
algae, and some bacteria use
sunlight, carbon dioxide, and
water to make food.
Photosynthesis
20. What part of the cell is a vast
system of interconnected sacks
located in the cell’s cytoplasm that
transports protein acting as a
highway for movement?
Endoplasmic Reticulum
(ER)
