Glucose Is Very Useful!

(This Post Contains 3 Comics)
Glucose is a very useful substance.  Therefore, photosynthesis’ main purpose is to MAKE GLUCOSE.  In this post, we’ll look at some of the most popular uses for glucose.

We can see that glucose is useful in:
(1) Providing energy
(2) Make cellulose (plant fiber)
(3) Make fruits sweet-tasting

There are more ways glucose are useful, but you get the idea…  Therefore, although photosynthesis makes both glucose and oxygen, glucose is THE product that TRULY MATTERS.

Note: The chemical formula for the glucose molecule is C6H12O6

Next Generation Science Standards:

MS-LS1-3.  Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

MS-LS1-6.  Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

MS-LS1-7.  Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.

HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

HS-LS1-3.  Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.

HS-LS1-5. Use a model to illustrate how photosynthesis transforms light energy into stored chemical energy.

HS-LS1-6.  Construct and revise an explanation based on evidence for how carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules.

HS-LS1-7.  Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy.

HS-LS2-3.  Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.

HS-LS2-5.  Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

Additional Information


Chloroplasts are organelles containing a special pigment called chlorophyll and are responsible for making photosynthesis happen.  Chloroplasts are usually found in plant cells.


They are the “ingredients” of a chemical reaction.  In a chemical reaction, reactants are used to produce “products”, which are the end results of a reaction.


Products are what a chemical reaction “makes” in the end.  For example, the main products of photosynthesis are glucose and oxygen.


Glucose is the simplest form of sugar and contains a lot of energy–think of the phrase “sugar-rush”.  Because it is “simple”, it can be easily absorbed into an organism’s body/cells to provide the organism with energy.
