Multiple Choice
Which organelle is found only in plant cells (and some algae) and is responsible for photosynthesis?
A
Mitochondrion
B
Ribosome
C
Endoplasmic reticulum
D
Chloroplast
Verified step by step guidance1
Identify the function described in the question: the organelle responsible for photosynthesis.
Recall that photosynthesis is the process by which light energy is converted into chemical energy, producing glucose and oxygen.
Understand that mitochondria, ribosomes, and endoplasmic reticulum have different functions: mitochondria generate ATP through cellular respiration, ribosomes synthesize proteins, and endoplasmic reticulum is involved in protein and lipid synthesis.
Recognize that chloroplasts are unique to plant cells and some algae and contain chlorophyll, the pigment that captures light energy for photosynthesis.
Conclude that the organelle responsible for photosynthesis and found only in plant cells and some algae is the chloroplast.
