How does a leaf transpire?

How does a leaf transpire?

Water moves from the soil into plant roots, up through the sapwood into the leaves. The water, warmed by the sun, turns into vapor (evaporates), and passes out through thousands of tiny pores (stomata) mostly on the underside of the leaf surface. This is transpiration.

What is stomatal transpiration?

Stomatal transpiration: It is the evaporation of water through stomata. Stomata are specialized pores in the leaves. They account for around 80 to 90% of the total water loss from the plants. Cuticular transpiration: Cuticle is an impermeable covering present on the leaves and stem.

Which refers to the loss of water from plant parts soil surface with the aid of sunlight?

Transpiration is the loss of water from the plant through evaporation at the leaf surface.

What is the process of runoff?

Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. Glaciers, snow, and rain all contribute to this natural runoff. Runoff also occurs naturally as soil is eroded and carried to various bodies of water.

What are the 2 types of runoff?

There are three major types of runoff depending on the source: surface flow, interflow, and base flow. These were discussed in Module 101 and are expanded upon here. Surface flow is water that has remained on the surface and moves as overland or channel flow.

Is runoff a process?

Surface runoff is the movement of water across the soil surface toward the stream channel. This process is more likely in areas with deep soil. Runoff, sometimes called quick response runoff, can refer to surface runoff only, but sometimes it is the combination of surface runoff plus interflow.

Is runoff good or bad?

Runoff is extremely important in that not only does it keep rivers and lakes full of water, but it also changes the landscape by the action of erosion. Runoff of course occurs during storms, and much more water flows in rivers (and as runoff) during storms.

What are the factors that affect runoff?

Meteorological factors affecting runoff:

  • Type of precipitation (rain, snow, sleet, etc.)
  • Rainfall intensity.
  • Rainfall amount.
  • Rainfall duration.
  • Distribution of rainfall over the drainage basin.
  • Direction of storm movement.
  • Precipitation that occurred earlier and resulting soil moisture.
