stomate การใช้

• They do it through pores on their leaves called stomates.
• When the temperature drops, the rhododendron is in danger of losing vital moisture through the stomates.
• The sacs that harbored ants had interior pores, or stomates, to take up carbon dioxide more easily, she said.
• Leaves are covered with small holes called stomates that allow them to exchange carbon dioxide and oxygen through photosynthesis, Kittredge explained.
• Researchers were able to make these conclusions based on the obvious accumulation of the nematodes on and within artificial stomates expelling CO 2.
• On cauliflower, Xcc infection via stomates causes black or brown specks, scratched leaf margins, black veins, and discolored curds.
• As the stomates open to take in carbon dioxide, they also lose some of the water the plant has taken up from the soil.
• Rhododendron leaves have stomates, a form of " breathing " pore, on their undersides, as do many plants, but cannot close them.
• The trichomes ( leaf hairs ) run along the mid-vein and the margins, further protecting the surface where the stomates are located, thus minimising water loss.
• If the plants take in more carbon dioxide, because more is available, Jackson speculates that they may lose less water because their stomates won't open as much.
• By curling, the leaves reduce the exposure of the stomates . ( I vaguely recall being told in an Arnold Arboretum class that the mechanism of the leaf curl is a result of cells contracting due to water loss caused by cold .)
