Multiple Choice
Which statement best describes the presence of mitochondria in plant and animal cells?
A
Mitochondria are present only in animal cells; plant cells rely exclusively on chloroplasts for ATP production.
B
Mitochondria are present in both plant and animal cells and are a major site of ATP production via cellular respiration.
C
Mitochondria are present only in plant cells; animal cells generate ATP only in the cytosol.
D
Mitochondria are absent from both plant and animal cells and are found only in prokaryotes.
Verified step by step guidance1
Recall the primary function of mitochondria, which is to produce ATP through cellular respiration, a process essential for energy supply in eukaryotic cells.
Understand that both plant and animal cells are eukaryotic and require ATP for various cellular activities, so they both contain mitochondria to fulfill this energy demand.
Recognize that plant cells have chloroplasts for photosynthesis, which produces glucose and oxygen, but mitochondria are still necessary to convert this glucose into usable ATP.
Note that animal cells lack chloroplasts but still have mitochondria to generate ATP from nutrients through cellular respiration.
Conclude that mitochondria are present in both plant and animal cells and serve as a major site of ATP production, making the statement about their presence in both cell types and their role in ATP production the correct description.
