Multiple Choice
Do plant cells have mitochondria, and what is their primary role in the cell?
A
Yes; they store genetic information for the entire cell and control nuclear division.
B
Yes; they are the primary site of photosynthesis and carbon fixation in plant cells.
C
No; only animal cells contain mitochondria, while plants rely solely on chloroplasts for ATP production.
D
Yes; they carry out cellular respiration to generate ATP.
Verified step by step guidance1
Step 1: Understand the question is asking whether plant cells have mitochondria and what their primary role is.
Step 2: Recall that mitochondria are organelles found in almost all eukaryotic cells, including plant cells, and are responsible for producing ATP through cellular respiration.
Step 3: Differentiate mitochondria from chloroplasts, which are the organelles in plant cells responsible for photosynthesis, not ATP production via respiration.
Step 4: Recognize that mitochondria generate ATP by breaking down glucose and other molecules in the presence of oxygen, a process called cellular respiration.
Step 5: Conclude that plant cells do have mitochondria, and their primary role is to carry out cellular respiration to generate ATP, providing energy for cellular activities.
