Do cells
make up
plants?
Cells make up all
living things.
What is the definition of a cell:
A cell is the smallest
unit capable of life
Robert Hooke discovered the first
cells. Cork Cells were thought to
have been these cells.
Anton von Leeuwenhoek was first
to observe one celled living things.
Cork cell
Answer: Small cells are
beneficial because they have
lots of surface area compared
to their volume!
How does this plant cell look different/similar from the cork cell?

Cells are Us
A person contains about 100
trillion cells. That’s
100,000,000,000,000 or 1 x
1014 cells.
There are about 200 different
cell types in mammals (one of
Red and
us).
Cells are tiny, measuring on
average about 0.002 cm (20
um) across. That’s about
1250 cells, “shoulder-toshoulder” per inch.

• Plant cells
• Animal cells
• Fungi cells
• Bacteria cells
• Protist cells
A way to remember the 5 types
of cells is to make up a sentence
using the first letter in each type.
Plant
Animal
Fungi
Bacteria
Protist
Circle the first letter in each cell
type
Plant
Animal
Fungi
Bacteria
Protist
Work with the people around you for two
minutes to come up with a sentences with
words starting with the letters P A F B P
Write your favorite sentence
down to help you remember later.

Plant Cells
• Plants are classified into
the Plant Kingdom.
• Plants may be grouped into
Vascular or non-vascular
• Plants are made up of
plant cells.
Plant cells have:
- a strong cell wall,
-large water vacuoles, and
-several chloroplast for
photosynthesis used in
energy & food production.
Plant cells
Cell membrane
• Plant cells are usually
square or rectangle
shaped.
Plant cells have:
-cell wall,
- cell membrane,
--chloroplasts, -nucleus,
-large vacuoles for food &
water, and
- cytoplasm to protect all
the internal organelles.

membrane
• Multi celled organisms
• Cytoplasm is the clear
jelly like matter that
protects the inside cell
organelles.
• Cell walls are found
in plant cells but not in
animal cells. They are
stiff, non-living cell
parts that help shape
the plant cell.
Review Question #1:
What do these plant cell
organelles do?
A
chloroplasts
C
vacuoles
B
cell wall
D
cytoplasm
Definitions and plant cell parts.
Cell Wall-provides shape and protection for
the plant, fungi, bacteria and algae cell.
Chloroplasts-a green structure that is used in
photosynthesis to harness the energy of the
sunlight.
Cell membrane, nucleus, mitochondrion,
cytoplasm, vacuole and ribosome defined
with animal cells.

Question #2:
• Which gas is used by plants
during photosynthesis?A
B
C
D
carbon dioxide
oxygen
nitrogen
phosphorus
Answer to question #2.
• You got it! A
• Plants use carbon
dioxide during
photosynthesis
and they excrete
(their waste)
oxygen.
Question #3:
• Which of these is the source of energy
for photosynthesis?
A
B
C
D
Gravity
Electricity
Magnetism
Sunlight
Answer to #3:
• Yes, sunlight D.
• Sunlight is the source
of energy for plant
photosynthesis.
What are some differences you
see between the plant and animal
cell?
Write them down on a paper to
hand in as you leave.
CELL MEMBRANE
Outer covering, protective layer
around ALL cells
For cells with cell walls,the cell
membrane is inside the cell wall
Allows food and air into the cell &
waste products out of the cell.
Cell Jobs

take notes.
CELL WALL
Provides structure and
protection for the plant,
Algae, fungi and bacteria
is made of cellulose
A cell wall is found in plants, algae, fungi, &
most bacteria.
Chloroplasts
Used in photosynthesis to harness the
energy of the sunlight
CELL MEMBRANE
Outer covering, protective layer
around ALL cells
For cells with cell walls,the cell
membrane is inside the cell wall
Provides structure and protection
for the plant, fungi, bacteria an
algae cell.
NUCLEUS
Control center of the cell
Directs all cell activities
Contains instructions for
everything the cell does
These instructions are
found on a hereditary
material called DNA
Usually the largest
organelle
Mitochondrion
Powerhouse of the cell providing energy.
CYTOPLASM
jelly-like fluid inside cell membrane
constantly flows
like protoplasm or
gak
Provides an enviornment
For organelles
Vacuole
Storage place for water, food and waste
Golgi Body
Gather molecules and combine them and
build vesicles.
Ribosome
Produces proteins
E.R. – Endoplasmic Reticulum
Transportation System
Lysosomes
Break down food particles
