Unit A – Lesson 1
What is everything living
composted of ?
Correct, cells!
All living things are made up of
cells.
• Bacteria 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.

• 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.

l
Chloroplast
holds
the cell together and
lets substances pass in
and out of its pores.
• Chloroplasts are
organelles in some
plant and protist cells.
They contain
chlorophyll that helps
the plant cell store solar
(SUN) energy.
• Photosynthesis.
• Plants are producers.
Review Question #1:
What do these plant cell
organelles do?
A
chloroplasts
C
vacuoles
B
cell wall
D
cytoplasm
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 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.
Animal Cells
nucleus
Each animal cell has:
-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
butterfly
