Final answer:
Both plant and animal cells have a nucleus, mitochondria, and an endoplasmic reticulum. Chloroplasts are exclusive to plant cells for photosynthesis.
Step-by-step explanation:
The organelles found in both plant and animal cells include the Nucleus, Mitochondria, and the Endoplasmic Reticulum (ER). Chloroplasts are not found in animal cells; they are specific to plant cells and other photosynthetic organisms. Both plant and animal cells contain a nucleus, which serves as the control center of the cell, maintaining the genetic material and coordinating cell activities. Mitochondria are the powerhouses of the cell, producing ATP through cellular respiration in both plant and animal cells. The ER consists of the rough ER, with ribosomes attached, participating in protein synthesis, and the smooth ER, involved in lipid synthesis and other metabolic processes without ribosomes. Chloroplasts, however, are specialized for photosynthesis in plant cells and are responsible for converting light energy into chemical energy.
