An athlete's muscle cells contain many mitochondria, while a plant's leaf cells contain both mitochondria and chloroplasts. Why do plant cells need both organelles for proper cellular function?
Question 5 options:

Mitochondria and chloroplasts perform exactly the same cellular functions in plants

Chloroplasts capture energy through photosynthesis; mitochondria release energy through cellular respiration

Plant cells are larger and need extra organelles for structural support purposes

Chloroplasts work during daylight hours; mitochondria work during nighttime hours exclusively

Chloroplasts capture energy through photosynthesis; mitochondria release energy through cellular respiration.

Explanation: Chloroplasts convert light energy into chemical energy (sugars and O2). Mitochondria oxidize those organic molecules to make ATP, the usable energy currency for cellular processes. Plants need both to produce energy-rich compounds and to extract ATP from them (mitochondria function continuously, not only at night).
