Adaptations of leaves to maximise gas exchange: They are thin which gives a short diffusion distance. They are flat which provides a large surface area. They have many stomata which allow movement of gases in and out of the air spaces inside the leaf to maintain a steep concentration gradient.

Web23 de ago. de 2024 · Leaves are adapted to increase the rate of diffusion of gases, and to reduce the rate of water loss by evaporation: A flat leaf shape increases the surface area … WebIt serves to funnel air to the lungs. The alveoli are the sites of gas exchange; they are located at the terminal regions of the lung and are attached to the respiratory bronchioles. The acinus is the structure in the lung where gas exchange occurs. The sac-like structure of the alveoli increases their surface area.
Web2 de dez. de 2014 · The leaf is the organ in a plant specially adapted for photosynthesis. You need to understand the structure of the tissues in a leaf together with their functions. Upper Epidermis: this is the tissue on the upper surface of the leaf. It produces a waxy layer, called the cuticle, which is not made of cells but is a waterproof barrier to prevent … WebAdaptations of exchange surfaces. For respiration, organisms need to take oxygen into their bodies and remove carbon dioxide.These gases diffuse across exchange surfaces, such as the lungs, so exchange surfaces are adapted to make diffusion as efficient as possible. Most gas exchange surfaces are extremely thin (sometimes just one cell …
WebCountercurrent flow of blood and water in opposite directions at the gills maintains a concentration gradient over the whole length of the gills. How are fish gills adapted for efficient gas exchange? Lamellae and filaments = large surface area to increase diffusion. Gill epithelium thin so short diffusion pathway. http://passmyexams.co.uk/GCSE/biology/structure-of-leaf.html
