WebJul 16, 2024 · How can sunken stomata reduce the amount of water lost through transpiration? Sunken stomata, which are responsible for the accumulation of moisture in the substomatal air gaps and lead to a low diffusion gradient, hence lowering the transpiration rate. What kinds of plants have stomata that are recessed? WebSep 20, 2024 · Answers. Water vapor accumulates in stomatal pits making the environment around the stomata humid, this lowers the saturation deficit. Water vapour accumulates … hand blown glass clown

WebFor transpiration to occur, water vapor leaving the stomata must diffuse through this motionless layer to reach the atmosphere where the water vapor will be removed by moving air. The larger the boundary layer, the slower the rates of transpiration. ... Some plants possess stomata that are sunken into the leaf surface, dramatically increasing ... WebCommon adaptations to reduce the rate of transpiration include: Thick waxy cuticle: The cuticle cuts down water loss in two ways: it acts as a barrier to evaporation and also the shiny surface reflects heat and so lowers temperature. ... Sunken stomata: Stomata may be sunk in pits in the epidermis; moist air trapped here lengthens the diffusion ... WebStomata help in gas exchange and prevents loss of water during transpiration.

WebTo reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce … WebAug 27, 2024 · Practical application: It is possible to reduce the rate of transpiration (abruptly but temporarily) of any plant by root pruning.. Conversely, the efficiency of the plant to absorb water can be improved through enhanced root development. 2. Leaf area and a number of stomata A plant with a greater total leaf area will transpire more water …

WebSep 19, 2024 · A better understanding of this phenomenon may result from examining the interactions between the leaf cuticle and stomata and from functional comparisons of … WebTemperature affects the transpiration rate in two ways. Firstly, at warmer temperatures water molecules move faster, and the rate of evaporation from stomata is therefore much …

WebMar 13, 2024 · Hint: Sunken stomata are stomata present in small pits in a leaf which helps reduce the rate of water loss due to transpiration. Complete answer: Sunken stomata are present in plants that are usually in areas of water scarcity i.e., arid areas or deserts where to prevent water loss due to transpiration. Plants generally have stomata on the ...
