Comparing Organelles to Body Systems
Comparing Organelles to Body Systems Cell Wall • A stiff wall surrounding the cell membrane of a plant cell needed for protection • Responsible for the shape/support of the cell Body System? Skeletal Protects organs and gives organism its shape/support Cell Membrane • A protective barrier between the cytoplasm and outside of the cell • Controls what enters and leaves the cell Body Systems? Integumentary System (Skin) Protects against invaders and also controls what enters and leaves an organism’s system. Cytoplasm • Gel-like fluid in which organelles are supported • Transports materials within the cell Body Systems? Circulatory transports materials around the body Nucleus • The control center of the cell and directs all cell activities Body Systems? Brain and Central Nervous System Controls most body functions Mitochondria • Mitochondria breaks down nutrients to release energy using oxygen (cellular respiration) Body Systems? Digestive Breaks down food into molecules used by an organism for energy release
