Performance Indicator
7.L.3A.2
Analyze and interpret data from
observations to describe different types
of cells and classify cells as plant,
animal, protist, or bacteria
Types of cells
Cells can be classify as
• Plant
• Animal
• Bacteria
• protist

Structures that are common to plant and animal
cells are the
• Cell membrane
• Nucleus
• Mitochondria
• vacuoles

Cells
Structures that are specific to plants are
• Cell wall
• Chloroplasts
Differences between plant and animal
Major structural differences between a plant
and an animal cell include:
• Plant cells have a cell wall, but animal cells do
not. Cell walls provide support and give shape
to plants
• Plant cells have chloroplasts, but animals cells
do not. Chloroplasts enable plants to perform
photosynthesis to make food.
Differences between plant and animal
• Plant cells usually have one or more large
vacuole(s), while animal cells have smaller
vacuoles, if any are present.
• Large vacuoles help provide shape and allow
the plant to store water and food for future
use. The storage function plays a lesser role in
animal cells, therefore the vacuoles are
smaller
Review
• Create a T- Chart and compare and contrast
plant and animal cells
Prokaryotic or Eukaryotic
• Prokaryotic organisms are cells that lack a
nucleus and membrane-bound organelles.
Bacteria compose the majority of prokaryotic
organisms.
Prokaryotic or Eukaryotic
• Eukaryotic organisms are cells that contain a
membrane bound nucleus and organelles
Plant, animal, and protist are eukaryotic.
Unicellular
• Unicellular organisms are composed of one
cell and would include most protists and
bacteria.
Photosynthetic or non-photosynthetic
• Cells that are photosynthetic contain
chloroplasts and the pigment chlorophyll. This
would include most cells of the plant kingdom
and some protist
• Non-photosynthesizing cells would lack
chloroplasts and chlorophyll. This would
include cells of the animal kingdom
