Which organelle is absent in animal cells?

Animal cells are eukaryotic cells that lack a cell wall and chloroplasts. Chloroplasts are specialized organelles that are responsible for photosynthesis in plants and some other organisms. They contain chlorophyll, a pigment that captures sunlight and converts it into energy that can be used by the cell. Animal cells, on the other hand, obtain energy through the process of cellular respiration, which takes place in organelles called mitochondria. Centrioles are also found in animal cells, and they are involved in cell division.
