Cells
Dr. Marjorie Anne Wallace,
Elementary Science Resource Teacher
All living things are made up of
cells.
• Bacteria cells
• Protozoan cells
• Fungi cells
• Plant cells and
• Animal cells
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. nucleus
Plant Cells • Multi celled organisms
• Cytoplasm is the clear
nucleus jelly like matter that
protects the inside cell
cytoplasm organelles.
• Cell walls are found
in plant cells but not in
Water animal cells. They are

wall parts that help shape

Water • Chloroplasts are
vacuole Chloroplast organelles in some
plant and protist cells.
They contain
chlorophyll that helps
l
nucleus the plant cell store solar
(SUN) energy.
• Photosynthesis.
• Plants are producers.
Review Question #1:
What do these plant cell
organelles do?
A B
chloroplasts cell wall
C D
vacuoles cytoplasm
Question #2:
• Which gas is used by plants
during photosynthesis?-
A carbon dioxide
B oxygen
C nitrogen
D 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 Gravity
B Electricity
C Magnetism
D Sunlight
Answer to #3:
• Yes, sunlight D.
• Sunlight is the source
of energy for plant
photosynthesis.

What do animal cells look like?
• Animal cells tend to be sphere or round shaped.
• Animal cells have:
-cell membrane to hold the cell together,
-cytoplasm a watery gel inside the cell,
-nucleus with a nuclear membrane, and
-sometimes small vacuoles where
food and chemicals are stored.
Each animal cell has:
Animal Cells -a cell membrane- holds cell
together and allows substances
in and out of the cell,
-cytoplasm- jelly like gel that
suspend organelles
inside the cell,
-a nucleus- the control center;
or the “Brain,” of the cell,
-nuclear membrane- allows
substances to pass in & out
of the nucleus.

Animal Kingdom
• Animals are classified
into the
Animal Kingdom.
Animals are consumers.
(They must eat food to live.)
• Animals can be grouped as
Invertebrates or vertebrates.
Invertebrate -No backbone
Vertebrates - Backbone present
