Answer
This statement is incorrect because section K, although it may lack certain pigments, would likely still have the cellular machinery to carry out aerobic respiration, provided that other conditions are favorable.
Step 2
B. light-independent reactions of photosynthesis can occur in cells from section K.

Answer
This statement is correct. Light-independent reactions, also known as the Calvin cycle, can occur if chlorophyll is present, which is the case in section K.
Step 3
C. there is chlorophyll present in cells from section K but not in cells from section M.

Answer
This statement is accurate. The images suggest that cells in section K contain chlorophyll, enabling photosynthesis, while cells in section M do not show any signs of chlorophyll.
Step 4
D. glucose would be manufactured from carbon dioxide and water in cells from section M but not in cells from section K.

Answer
This statement is correct. Since cells in section K contain chlorophyll, they can produce glucose through photosynthesis, whereas cells in section M lack chlorophyll and thus cannot synthesize glucose from carbon dioxide and water.
