Biology Quiz: Identify the Organelle That Builds Proteins
Biology
Grade 7 (Junior High School)
Question Content
4. Which organelle builds proteins? (Paragraph 2) A. Golgi body B. Ribosome C. Chloroplast D. Lysosome
Correct Answer
B
Detailed Solution Steps
1
Step 1: Recall the function of each listed organelle: Golgi bodies process and package proteins, ribosomes synthesize proteins, chloroplasts perform photosynthesis, lysosomes break down waste.
2
Step 2: Identify the organelle responsible for protein synthesis: Ribosomes, either free in the cytoplasm or attached to the endoplasmic reticulum, are the sites of protein production.
3
Step 3: Select option B as the correct answer.
Knowledge Points Involved
1
Ribosome for Protein Synthesis
Ribosomes are small, non-membrane-bound organelles found in all living cells. They read genetic instructions from messenger RNA (mRNA) and assemble amino acids into polypeptide chains, which fold into functional proteins. This process is called protein synthesis, a core cellular function.
