Because flatworms are so simple, there is no organ … Web18 de abr. de 2016 · How the leaf is adapted for gas exchange: Leaves are broad: large SA for diffusion. Thin: gases only need to travel a short distance to reach needed cells.; Air spaces in leaf: increases SA for gas exchange, letting gases move easily between cells. Stomata at lower surface: lets gases diffuse in/out. Stomata closes when it gets dark: …
WebAnswer (1 of 2): First, flatworms are thin enough that they can perform all necessary gas exchange through the body surface (tegument), acquiring oxygen and discharging … Web14 de mai. de 2024 · The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Figure 16.2.4.1 Stoma. Normally stomata open when the light strikes the leaf in the morning and close during the night.
WebGas exchange is the ‘swapping’ of gasses - absorbing oxygen into the blood and removing carbon dioxide from the blood. Diffusion moves oxygen out of the alveoli and into the … WebTracheal System of an Insect. All insects possess a rigid exoskeleton with a waxy coating that is impermeable to gases. Insects have evolved a breathing system that delivers oxygen directly to all the organs and tissues of their bodies. A large number of tracheoles run between cells and into the muscle fibres - the site of gas exchange.
