The cytoplasm is the site where most cellular activities occur, such as many metabolic pathways, and processes such as cell division.
do you mean cytoplasm? if so then it is found in both animals and plants (it's everything within the cell membrane). For example, the cytosol is the liquid that is in the cytoplasm as well as organelles.
Leaves are the main site for photosynthesis in plants, where they absorb sunlight and carbon dioxide to produce energy in the form of glucose. They also help regulate water loss through transpiration and provide a surface for gas exchange, enabling the plant to take in carbon dioxide and release oxygen. Additionally, leaves can store nutrients and can serve as protection for the plant.
