Which of the following is a similarity between animal and plant cells?

• B. Both contain membrane-bound organelles such as a nucleus.
• C. Both lack mitochondria.
• D. Both have a rigid cell wall made of cellulose.

Answer: (B)

Verified step by step guidance

1. Understand the question: The problem is asking for a similarity between animal and plant cells. Carefully analyze the options provided to identify the correct similarity.
2. Recall the key features of animal and plant cells: Both are eukaryotic cells, meaning they have membrane-bound organelles such as a nucleus, mitochondria, and endoplasmic reticulum. However, there are also differences, such as the presence of chloroplasts and a rigid cell wall in plant cells.
3. Evaluate the first option: 'Both perform photosynthesis using chloroplasts.' This is incorrect because only plant cells (and some algae) have chloroplasts for photosynthesis, not animal cells.
4. Evaluate the second option: 'Both contain membrane-bound organelles such as a nucleus.' This is correct because both animal and plant cells are eukaryotic and share this feature.
5. Evaluate the remaining options: 'Both lack mitochondria' is incorrect because both animal and plant cells have mitochondria for energy production. 'Both have a rigid cell wall made of cellulose' is also incorrect because only plant cells have a rigid cell wall made of cellulose, while animal cells lack a cell wall.
