Comparing Plant and Animal
Cells
Chapter 1 Lesson 2
What we already know…
• All living things are ___________________________________
• Some animals and plants are made of _______________________
• and some are only made of __________________________
• But, plant and animals cells are not identical
Similarities of Plan and Animal Cells
• Both have a
__________________________
• Cell membranes are a thin layer
that surrounds and holds cells
together
• Kind of like how skin holds us
together!
• Both are filled with
_______________________
• Cytoplasm is a gel like
substance containing
chemicals needed by the
cell.
• Both cells have a
_________________________
• The Nucleus is the information and
control center of the cell.
• Kind of like your brain!
• The nucleus is also where
______________ is stored.
• DNA is the chemical inside cells that
stores information about an organism.
Difference:
• Some large animal cells have more than
one nucleus. All plant cells only have
one.
• Both have
_____________________________
• Mitochondria is an organelle
that uses oxygen to break down
food and release energy in
chemical bonds.
• Kind of like your digestion
system!
Difference
• Animal cells mainly use
Mitochondria for their energy.
Plants use something called
chloroplast.
• Both have
____________________
• Vacuoles store
substances such as
food, water, and waste
products
• Like a storage facility
Difference
• Animal cells have many
small Vacuoles. Plants
have one large vacuole.
• Both have
_______________
• Ribosomes are a
protein builder
of the cell
• They both have
_____________________
_____________________
• Endoplasmic Reticulum
are a system of tubes
that processes and
transports proteins
outside the cell.
• They both have
__________________
__________________
• Golgi Bodies package
and distribute
proteins that provide
structure to the cell
Plant Cells Have
__________
________________
• Cell Walls are the outer part of a
plant cell that provides structure to
the cell
Plant Cells Have _______________________________
• Chloroplasts capture the light energy from the sun to make food
Animal cells have
________________________
• Lysosomes break down
substances in the cell.
Cells Store and Use energy
• The energy that cells need comes originally from the _______.
• Chloroplasts in plant cells trap the sun’s light energy and change it
into chemical energy.
• The chemical energy is stored in chemical bonds between
___________ of carbon, hydrogen, oxygen.
• Atoms are the basic unit of matter.
Cells Store and Use energy
• Chemical bonds hold the atoms of carbon, hydrogen, and oxygen
together to form _________________________.
• Molecules are the smallest particle of a substance that has all the properties
of the substance.
• Cells can combine these molecules with other atoms to form larger
molecules.
Cells Store and Use energy
• Both plant and animal cells break down these molecules by breaking
the ____________________ ____________________.
• Energy is released when these bonds are broken and the cells can
either use it or store it.
Cells Store and Use energy
• The mitochondria in plant and animal cells use oxygen to release the
energy in these chemical bonds.
• Cells store energy in _________________ __________________.
• ATP molecules are high-energy molecules that store energy in a form the cells
can easily use.
• When the cells need energy, the ATP is broken down to release
energy.
Cells Store and Use Information
• Remember: the nucleus in plant and animal cells is the control center
of the cell and contain the DNA of the cell.
• The DNA has _______________ for all the cell’s activities.
• One activity is putting together protein molecules.
• DNA and _________ molecules work together in the cell to make
these proteins.
Cells Store and Use energy
• The DNA in the cell’s nucleus determines what __________of cell it is.
• When a cell divides into two cells, the DNA is copied so that each cell
has the same DNA instructions.
