Plants have chloroplasts and carry out photosynthesis, have cellulose cell walls, store carbohydrates as starch or sucrose
Animals lack chloroplasts and cannot photosynthesize, have no cell walls, have nervous coordination and can move, store carbohydrates as glycogen
Fungi cannot photosynthesize, have a mycelium structure with hyphae, some are single-celled, have chitin cell walls, use saprotrophic nutrition, store carbohydrates as glycogen
Protoctists are microscopic single-celled, some have animal-like features, some have chloroplasts and are more plant-like
