STUDY GUIDE/Flashcards: Cell Test
Why was the invention of the
microscope important?
The invention of the microscope made it
possible for people to discover and learn
about cells.
Who was Anton von Leeuwenhoek? Anton von Leeuwenhoek was the first person
to observe what are now called bacteria.
What is the Cell Theory?
The Cell Theory:
a. Cells are the basic unit of
structure and function in living
things.
b. All cells are produced from other
cells.
c. All living things are composed of
cells.
What is the function of the cell
wall?
The cell wall protects and supports the cell
and is found only in the plant cell.
What is the function of the cell
membrane?
The cell membrane controls what enters and
leaves the cell.
What is the function of the
mitochondria?
Mitochondria produce most of the energy
needed by the cell.

What is the function of the
ribosome?
Ribosomes produce proteins in the cell.
What is the function of the
lysosome?
Lysosomes (clean-up crew) release chemicals
that break down large food particles into
smaller ones.

What did Leeuwenhoek discover?
Leeuwenhoek viewed single-celled organisms in
pond scum which he called animalcules. Today
we know them as protists.
How did Matthias Schleiden
contribute to the cell theory?
Scientist Matthias Schleiden contributed to
the cell theory by concluding that all plant
parts were made of cells.
NUCLEUS
the brain of the cell that contains DNA and
controls all of the cell’s activities.
GOLGI BIDY
the mailroom of the cell that receives,
packages, and distributes proteins to other
parts of the cell.
MITOCHONDRIA
the power house of the cell where respiration
takes place (energy is produced).
