Multiple Choice
In a plant cell, what is the primary function of mitochondria?
A
Synthesize proteins by translating mRNA on ribosomes attached to the rough endoplasmic reticulum.
B
Store water and maintain turgor pressure as the main central vacuole.
C
Produce ATP by aerobic cellular respiration (e.g., via the citric acid cycle and oxidative phosphorylation).
D
Capture light energy to generate sugars through photosynthesis.
Verified step by step guidance1
Identify the organelle in question: mitochondria are membrane-bound organelles found in most eukaryotic cells, including plant cells.
Recall the primary role of mitochondria: they are known as the 'powerhouses' of the cell because they generate energy in the form of ATP.
Understand the process involved: mitochondria produce ATP through aerobic cellular respiration, which includes the citric acid cycle and oxidative phosphorylation.
Differentiate mitochondria from other organelles: for example, protein synthesis occurs on ribosomes and the rough endoplasmic reticulum, water storage and turgor pressure maintenance occur in the central vacuole, and photosynthesis occurs in chloroplasts.
Conclude that the primary function of mitochondria in plant cells is to produce ATP by aerobic cellular respiration, providing energy necessary for various cellular activities.
