Which two structures are present in a palisade cell but not in a liver?

Explanation

In Biology, there are different types of cells with different structures. The question is asking which two structures are present in a palisade cell but not in a liver. Palisade cells are found in plant leaves and are responsible for photosynthesis. The liver, on the other hand, is a vital organ in animals responsible for detoxification, protein synthesis, and many other functions. The options given are cell wall and cytoplasm, cell wall and chloroplast, cell membrane and cytoplasm, and cell membrane and chloroplast. The correct answer is option B, which states that cell wall and chloroplast are present in palisade cells but not in the liver. The cell wall is a rigid layer that surrounds plant cells, providing support and protection. Chloroplasts are organelles found in plant cells responsible for photosynthesis, the process of converting light energy into chemical energy. Palisade cells are specialized for photosynthesis; hence, they have chloroplasts, while the liver does not need chloroplasts since it has no role in photosynthesis. To sum up, the correct answer to the question is option B, which states that cell wall and chloroplast are present in a palisade cell but not in a liver.
