Final answer:
Animal cells contain centrosomes and lysosomes, which are absent in most plant cells. Conversely, plant cells possess a cell wall, chloroplasts, and plasmodesmata, which animal cells lack.
Step-by-step explanation:
The organelles found in animal cells but absent in plant cells include the centrosome and lysosomes. The centrosome is a microtubule-organizing center that contains centrioles, which aid in cell division and are not found in most plant cells.
Lysosomes are organelles that function as the cell's "garbage disposal" by breaking down waste materials and cellular debris. Plant cells typically use vacuoles for this purpose.
In contrast, plant cells have organelles such as the cell wall, chloroplasts, plasmodesmata, and plastids, which are not found in animal cells. These differences highlight the unique functions and adaptations of plant and animal cells in their respective environments.
