氣孔的結構和開合原理是什么求大神幫助？

氣孔[stoma]，葉、莖及其他植物器官上皮上許多小的開孔之一,高等陸地植物表皮所特有的結構。

狹義上常把保衛(wèi)細胞之間形成的凸透鏡狀的小孔稱為氣孔。有時也伴有與保衛(wèi)細胞相鄰的2—4個副衛(wèi)細胞。把這些細胞包括在內是廣義的氣孔（或氣孔器）。緊接氣孔下面有寬的細胞間隙（氣室）。氣孔在碳同化、呼吸、蒸騰作用等氣體代謝中，成為空氣和水蒸汽的通路，其通過量是由保衛(wèi)細胞的開閉作用來調節(jié)，在生理上具有重要的意義。氣孔通常多存在于植物體的地上部分，尤其是在葉表皮上，在幼莖、花瓣上也可見到，但多數(shù)沉水植物則沒有。1 氣孔的分布 不同植物的葉、同一植物不同的葉、同一片葉的不同部位(包括上、下表皮)都有差異，且受客觀生存環(huán)境條件的影響。浮水植物只在上表皮分布，陸生植物葉片的上下表皮都可能有分布，一般陽生植物葉下表皮較多。2 氣孔的類型 雙子葉植物的氣孔有四種類型：①無規(guī)則型，保衛(wèi)細胞周圍無特殊形態(tài)分化的副衛(wèi)細胞；②不等型，保衛(wèi)細胞周圍有三個副衛(wèi)細胞圍繞；③平行型，在保衛(wèi)細胞的外側面有幾個副衛(wèi)細胞與其長軸平行；④ 橫列型，一對副衛(wèi)細胞共同與保衛(wèi)細胞的長軸成直角.圍成氣孔間隙的保衛(wèi)細胞形態(tài)上也有差異，大多數(shù)植物的保衛(wèi)細胞呈腎形，近氣孔間隙的壁厚，背氣孔間隙的壁??；稻、麥等植物的保衛(wèi)細胞呈啞鈴形，中間部分的壁厚，兩頭的壁薄。3 氣孔的開閉機理 當腎形保衛(wèi)細胞吸水膨脹時，細胞向外彎曲，氣孔張開，而保衛(wèi)細胞失水體積縮小時，壁拉直，氣孔關閉；啞鈴形保衛(wèi)細胞吸水時兩頭膨脹而中間彼此離開，氣孔張開，失水時兩頭體積縮小中間部分合攏，氣孔關閉?？梢姎饪走\動的原因主要是保衛(wèi)細胞吸水膨脹引起的。4 影響氣孔運動的主要因素 4．1 光照引起的氣孔運動 保衛(wèi)細胞的葉綠體在光照下進行光合作用，利用CO2，使細胞內pH值增高，淀 粉**酸化酶水解淀粉為**酸葡萄糖，細胞內水勢下降．保衛(wèi)細胞吸水膨脹，氣孔張開；黑暗里呼吸產生的CO2使保衛(wèi)細胞的pH值下降，淀粉**酸化酶又把葡萄糖合成為淀粉，細胞液濃度下降，水勢升高，保衛(wèi)細胞失水，氣孔關閉。保衛(wèi)細胞的滲透系統(tǒng)也可由K 來調節(jié)。光合作用光反應(環(huán)式與非環(huán)式光合**酸化)產 生ATP，通過主動運輸逆著離子濃度差吸收K ，降低保衛(wèi)細胞水勢，吸水使氣孔張開。注意：①如果光照強度在光補償點以下，氣孔關閉；②在引起氣孔張開的光質上以紅光與藍紫光效果最好；③景天科植物夜晚氣孔張開，吸收和貯備CO2(形成蘋果酸貯于液泡中)，白天氣孔關閉，蘋果酸分解成丙酮酸釋放CO2進行光合作用。4．2 二氧化碳影響氣孔運動 低濃度CO2促進氣孔張開，高濃度CO2使氣孔迅速關閉，無論光照或黑暗皆如此。抑制機理可能是保衛(wèi)細胞pH下降，水勢上升，保衛(wèi)細胞失水，必須在光照一段時間待CO2逐漸被消耗后，氣孔才迅速張開。4．3 溫度影響氣孔運動 氣孔張開度一般隨溫度的上升而增大，在30％左右達到最大，低溫(如10％ 以下)雖長時間光照，氣孔仍不能很好張開，主要是淀粉**酸化酶活性不高之故，溫度過高會導致蒸騰作用過強，保衛(wèi)細胞失水而氣孔關閉。4．4 葉片含水量影響氣孔運動 白天若蒸騰過于強烈，保衛(wèi)細胞失水氣孔關閉，陰雨天葉子吸水飽和，表 皮細胞含水量高，擠壓保衛(wèi)細胞，故白天氣孔也關閉。
