Believe it or not, there are many similarities between plants and
animals. They are both living things that are made of cells with many
of the same organelles that perform the same function. There are,
however, some obvious differences between plants and animals. Plants
do not breath with lungs, but they do undergo respiration taking in
carbon dioxide (CO2) and expelling oxygen (O2) while animals and
humans take in that O2 and expel CO2. Plants are made of plant cells
that are box-like and surrounded by a cell well to support and protect
plants that are much more fragile than humans.

One of the major differences between plant cells and animal cells
is that plant cells contain special organelles called chloroplasts. The
important process of photosynthesis occurs inside each of these
chloroplasts. The chloroplasts contain the green pigment chlorophyll.
Chlorophyll molecules trap energy from the sun and use it to transform
carbon dioxide (CO2) and water (H2O) into a simple sugar called glucose.
Plants (and other living things) use glucose as a food source. Oxygen is
also produced during photosynthesis. Photosynthesis can be summarized
in a chemical equation written like this:

in a chemical equation written like this:
CO2 + H20 + energy (from sunlight)
CO2 + H20 + energy (from sunlight)
glucose (sugar) + O2
In the equation above, you’ll see that plants need 3 major items for
photosynthesis to work: carbon dioxide, water, and energy from sunlight.
Those 3 items combine together to produce glucose (a sugar used as a
food source for the plant) and oxygen. Again, this process occurs in the
chloroplasts of each plant cell & makes plants very unique compared to
animals!

Writing About Reading
Instructions:
Cut and paste the cell & chloroplast in your notebook as flip flaps. Write information from the passage under each flip
flap. Then cut out the plant and sun gluing down into notebook. Label all parts of photosynthesis (the needs and
byproducts) with arrows around the diagram. After you’re finished, respond to the the writing prompt.
