Photosynthesis/Respiration Test Review

Autotrophs differ from heterotrophs in that only autotrophs

• require carbon dioxide for cellular respiration

• release oxygen as a product of cellular respiration

• synthesize nutrients using carbon dioxide and water

• break down sugars to assemble other molecules

Coleus is a type of plant that has many variations in its leaves. Many coleus plants have chloroplast-rich areas on the edge of the leaf. Other areas in the middle lack chloroplasts. A student exposed the coleus leaf to sunlight. Later, starch indicator was added to the entire leaf. The diagram below shows the result of the experiment.

Which statement is a valid claim, supported by evidence from this experiment?

• Chloroplasts are necessary for the production of starch indicator

• Starch indicator causes leaves to produce oxygen.

• Chloroplasts are necessary for the production of starch.

• Water is necessary for the production of starch.
