Plant and Animal Cells
Which 2 organelles do you only find in plant cells?
Cell Wall and Chloroplast
Plant and Animal Cells
Which organelle do you only find in animal cells?
Centriole
Plant and Animal Cells
What other differences are there?
•
•
Animal cells are any shape, plant cells are square
Animal cells have small vacuoles, plant cells have a large
central vacuole
Specialized Animal Cells
• All animal cells begin as Stem Cells which are
unspecialized cells that have the ability to
differentiate (change) into any type of cell.
• The cells in your body
all have a specific job,
so they specialize
(form specific
structures/features) in
order to do this
Specialized Animal Cells - Types
1) Red Blood Cell (Erythrocytes)
• Transports gases using hemoglobin (protein)
• Does not have a nucleus so it can carry more
Specialized Animal Cells - Types
2) White Blood Cell (Leukocytes)
• Fights off infections and foreign cell in the
body
Specialized Animal Cells - Types
3) Neuron (Nerve Cell)
• Transmits electrical signals to and from the
brain
Specialized Animal Cells - Types
4)Epithelial Cell (Skin and Tissue Cell)
• Cover, protect and line the body. Also allow
for absorption in intestines/lungs
Specialized Animal Cells - Types
5) Muscle Cell – contract (become shorter) to
create movement, there are 3 types:
a) Skeletal
b) Cardiac (Heart)
c) Smooth
Specialized Plant Cells
• Plant cells have their own type of
unspecialized cells also, they are called
Meristem Cells.
They can also
change into any
type of cell.
Specialized Plant Cells - Types
1) Root Hair Cell
• Found in the roots of plants
• Increase surface area so the plant can absorb
more water/nutrients
Specialized Plant Cells - Types
2) Palisade Cell (Leaf Cell)
• Found in the leaves of plants
• Have a lot of chloroplasts so they can perform
photosynthesis
Specialized Plant Cells - Types
3) Xylem Vessel
• Found in the stem of plants (the vascular
portion)
• Transports water/minerals from soil into the
plant
Specialized Plant Cells - Types
4) Phloem Vessel
• Found in the stem of plants (the vascular
portion)
• Transports food (sugar from photosynthesis) up
and down the rest of the plant

What type of cell creates
the linings in the body?
Epithelial Cells
Review Time
How do root hair cells
help plants survive?
They increase surface area to
absorb more water/nutrients
Review Time
What are the two
vascular cells in plants?
Xylem and Phloem
Review Time
What is the difference
between xylem and phloem?
Xylem transports water/minerals
up the stem
Phloem transports food (sugars)
up and down the stem
Review Time
What is the name of the
stem cells in plants?
Meristem Cells
