In a plant cell, organelles such as chloroplasts, cell walls, and central vacuoles are required, while in an animal cell, they are not necessary. Chloroplasts are essential for photosynthesis, converting sunlight into energy for the plant. Cell walls provide structural support and protection for the plant cell, helping it maintain its shape and integrity. Central vacuoles store water, nutrients, and waste products, helping regulate the internal pressure and maintain turgidity in plant cells. These organelles are not needed in animal cells because animals do not undergo photosynthesis, have a flexible cell membrane instead of a rigid cell wall, and do not require a central vacuole for water and nutrient storage.
