Who invented the compound
microscope in the 1500s?
Remember: He put two magnifying
glasses together in a tube.
Hint: His initials are Z.J.
Zacharias Janssen
Who invented a more
advanced microscope than
the compound microscope?
This scientist’s microscope
magnified objects up to 270 times
their actual size.
Anton van Leeuwenhoek
Who observed slices of cork
under a microscope and
called the empty spaces he
observed “cells”?
Hint: His initials are R.H.
Robert Hooke
In the mid 1800s what
scientist concluded that all
animals are made up of cells?
Hint: His initials are T.S.
Theodore Schwann
In the mid 1800s what
German Scientist observed
that plants are made of cells?
Hint: His initials are M.S.
Matthias Schleiden
What are three differences
between animal cells and plant
cells?
1. Plant cells have cell walls; Animal
cell don’t.
2. Plant cells are always geometric in
shape; animal cells look like blobs
with no definite shape.
3. Some plant cells have chloroplasts;
animal cells never have chloroplasts.
What is the function of the
chloroplasts in a plant cell?
They make photosynthesis
happen! Through
photosynthesis, plants make
their own food.
DAILY DOUBLE!!
What are two organelles only
found in plant cells?
Chloroplasts & Cell Walls!
What two plant cells did we
observe under a microscope in
class?
The onion cell &
the elodea cell
What liquid did we need to use to
see the onion cell under the
microscope?
Iodine!
What do animal cells look like?
What is their shape?
They look like blobs. They
have no definite shape.
DAILY DOUBLE!!
Why is the cell theory important?
The cell theory is important
because it suggests that all living
organisms are related.
Name the three parts of the
cell theory.
1. All living things are made of
cells.
2. Cells are the basic unit of
structure and function in ALL
living things.
3. ALL living cells are made
from other living cells.
Does an animal cell have a
cell wall?
No, they don’t have cell walls, but
they do have cell membranes!
DAILY DOUBLE!!
Which organelle is called “the
power house” of the cell?
Hint: It releases energy needed for the
cell to function properly.
The mighty mitochondria!
What organelle is the control
center of the cell?
The nucleus!
What organelle contains DNA
and the genetic code of heredity
for the cell?
the chromosome!
What organelle is a sac that
stores water, food, or waste?
Hint: Plants have a large one of these
that stores water.
Vacuole!
DAILY DOUBLE!!
What organelle makes proteins
from raw materials in the
cytoplasm?
Ribosome!
