In an introductory comparison of plant and animal eukaryotic cells, which organelles/structures are typically found only in animal cells (and not in plant cells)?

• A. A cell wall made of cellulose and plasmodesmata
• B. Chloroplasts and a large central vacuole
• C. Centrioles (in centrosomes) and lysosomes
• D. Mitochondria and ribosomes

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the key differences between plant and animal eukaryotic cells by focusing on their unique organelles and structures.
2. Step 2: Identify organelles commonly found only in plant cells, such as the cell wall made of cellulose, chloroplasts, and a large central vacuole.
3. Step 3: Recognize organelles present in both plant and animal cells, like mitochondria and ribosomes, which are essential for energy production and protein synthesis respectively.
4. Step 4: Focus on organelles typically found only in animal cells, such as centrioles (which are part of centrosomes involved in cell division) and lysosomes (which contain digestive enzymes).
5. Step 5: Conclude that centrioles and lysosomes are the organelles/structures unique to animal cells in this comparison, distinguishing them from plant cells.
