✓

Plants transport water and minerals via xylem (upward, by transpiration pull) and sugars via phloem (bidirectional). Transpiration is the evaporation of water through stomata. In humans, the heart (4 chambers) pumps blood through arteries (away from heart), veins (toward heart), and capillaries (exchange). Blood components: red blood cells (haemoglobin carries O₂), white blood cells (immunity), platelets (clotting), and plasma.
