Plant cells contain organelles such as a nucleus, cell membrane, cell wall, vacuole, cytoplasm, chloroplasts, and chloroplasts that each have a specific structure and function. The nucleus controls the cell, the cell membrane controls molecule movement, the cell wall protects and gives shape, the vacuole stores food, the cytoplasm may contain stored food, chloroplasts produce sunlight using chlorophyll, and starch and grains store carbohydrates while the nucleus membrane protects the nucleus.
