6. Sam places a small green plant inside a test tube and seals the test tube inside a Mask The flask has a glass tube sticking out of the stopper, so he can periodically
analyze the gas in the Nask. He places the task outside in direct sunlight and collects
and analyzes the gas in the task during the day and at night to compare the amounts
of carbon dioxide and oxygen.
His analysis shows that during the day, the amount of oxygen in the flask increases
while the amount of carbon dioxide decreases. He concludes that this is due to the
process of photosynthesis. He adds that plants produce glucose, a type of carbohydrate
by using carbon dioxide water and light energy, and store this energy in the chemical
bonds of the glucose molecule, while building large polysaccharides,
What type of large polymer is synthesizes (created) by plants to store energy for
Later use?
A Polysaccharide: Starch
B. Polysaccharide: Chitin
C. Polysaccharide Glycogen
D. Polysaccharide cellulose
