Transport in systems
Plants
Root hair cells
Water enters through osmosis
Mineral salts enter through diffusion
Increased surface area in cell structure
Transport of nutrients
Xylem (Water)
Transfers water and mineral salts upwards
Innermost in the stem
Phloem (Food)
Transfers food around the plant
Outermost in the stem
Stomata
Oxygen diffuses from inside stomata to atmosphere
Carbon dioxide diffuses from atmosphere to stomata
Humans
Heart
Blood vessels
Arteries
Transport blood away from heart
Transport blood rich in oxygen
Veins
Transport blood towards heart
Transport blood rich in waste material
Capillaries
Exchange of substances between cells and blood
Waste materials diffuse from body into capillaries
Oxygen diffuses from capillaries to body
Blood
Plasma
Transports waste, nutrients and CO2
White blood cells
Defend against pathogen
Red blood cells
Transports oxygen
No nucleus
Biconcave to increase surface area
hemoglobin to carry oxygen (Red)
Platelets
Blood clotting
Transport of particles
Osmosis (water only)
Water enters through osmosis
Enters from region of lower water potential to higher water potential
Partially permeable membrane
Diffusion
Substance diffuses from region of higher concentration to lower concentration
Diffuses until reaches an equal amount of the substance everywhere
