Final answer:
Plant cells have chloroplasts and cell walls, which animal cells lack. Chloroplasts enable photosynthesis, and cell walls provide structure and support for plants.
Step-by-step explanation:
Plant cells have chloroplasts and cell walls, which are not present in animal cells. The correct answer to the question is:
d. chloroplasts, cell walls
Both plant and animal cells have a nucleus and mitochondria among other common organelles. However, certain structures are unique to plant cells, providing necessary functions for plant life. Chloroplasts are the site of photosynthesis, a process that converts light energy into chemical energy. This capability is critical for the plant's production of food via photosynthesis. Cell walls, made predominantly of cellulose, give plant cells their rigidity and structure, helping to support the plant. In summary, while many organelles are common to both cell types, it's specifically the presence of chloroplasts and cell walls that differentiate plant cells from animal cells.
