Karten in diesem Stapel (6)
- 1Explain how mammal lungs have a large surface areaThey have lots of alveoli
- 2How do plant leaves have a large surface area?Leaves are very large to abosrb as much sunlight as possible
- 3How do mammal lungs reduce their thickness to improve the uptake of oxygen?Alveoli are one cell thick
- 4How does the principle of concentration gradient relate to mammal lungs?Blood has a low concentration of oxygen and lungs have a very high oxygen concentration so more diffusion takes place
- 5Explain how the principle of concentrastion gradient relates to plant leavesThere is a high concentration of CO2 in the air compared to the leaf so CO2 enters the leaf through the stoma
- 6How are plant leaves protected from drying out?The transpiration system keeps the leaf surfaces moist
