The correct answer is d) chloroplast and cell wall.
Chloroplasts are the organelles responsible for photosynthesis, allowing plants to convert sunlight into energy. This is a key process that distinguishes plant cells from animal cells, as animal cells do not have chloroplasts.
Additionally, plant cells have a cell wall made of cellulose, which provides structural support and protection. Animal cells lack a cell wall, having only a flexible cell membrane instead.
On the other hand, ribosomes and mitochondria are found in both plant and animal cells. Ribosomes are the sites of protein synthesis, while mitochondria are involved in energy production. Therefore, the presence of chloroplasts and cell walls are unique to plant cells.
