Although most cells eukaryotic cells
have the same basic stuff, there are
some differences between animal cells
and plant cells.
SHAPE
• Animal cells are roundish or blob shaped
• Plant cells are kinda rectangular
• Plant cells often look like bricks in a brick wall
COLOR
• Animal cells are pink, clear, red, orange,
bluish, (anything but green)
• Plant cells are green or sometimes clear if the
cell is part of a root that doesn’t see sunlight)
OUTER STRUCTURE
• Animal cells do not have a cell wall, only a cell
membrane, that’s why they’re blob shaped.
• Plant cells have a cell wall, that’s what makes
stems rigid, and makes plant cells form
rectangular shapes in a brick wall pattern.
GETTING ENERGY
• Animal cells need to absorb sugar for food, so
they do not have chloroplasts.
• Plant cells make their own food from sunlight,
so they have chloroplasts to absorb sunlight.
VACUOLES
• Animal cells have many small vacuoles.
• Plants need lots of water to conduct
photosynthesis, so they need big vacuoles to
store lots of water.
LYSOSOMES
• Animal cells have to take in food, so they have
more waste products to digest, and thus more
lysosomes.
• Plant cells have very little waste, so they have
very few lysosomes.
MITOCHONDRIA
• Both plant cells and
animal cells have
mitochondria.
• Animal cells that need to
move a lot may have more.
• Plant cells convert sunlight
to sugar, then the
mitochondria convert sugar
to ATP
RIBOSOMES
• All cells need to make
protein.
• “Protein makes the
world go round.” It is
not just muscle
A third type of cells:
• Prokaryotes are
bacteria
• Eukaryotes are
“normal” cells of
plants and animals
GENETIC MATERIAL
• Genetic material in bacteria is not contained
inside a nucleus.
MOBILITY
• Some bacterial cells can
move.
• Flagella – long whip-like
tail
• Cilia – short little hairs
like a millipede
SHAPE
• Prokaryotes come in 3 basic
shapes:
• Spiral Shapes like Borrelia
• Rod Shapes like Esherichia
• Sphere Shapes like
Staphlococcus
OUTER COVERING
• Bacterial cells have both
a cell wall and a cell
membrane.
• Some bacteria can form
endospores. These
“capsules” can survive
harsh conditions and
remain dormant for
years.
GETTING ENERGY
• Some bacteria are
autotrophs, and make food
from sunlight.
• Some bacteria are
autotrophs and make food
from sulfur or other
chemicals.
• Some bacteria are
hetrotrophs and break
down food for energy
