(By mounting a defence response, plants can make themselves less palatable or even indigestible to the insect attackers.)<\/li>\n<li>The molecular cascade is mediated by calcium, a common mediator of chemical and electrical signals found throughout biology.<\/li>\n<\/ul>\n<h2>What are Volatiles?<\/h2>\n<ul>\n<li>These are\u00a0elements or compounds that change from\u00a0solid or liquid state into vapour at relatively low temperatures.<\/li>\n<li>The most common volatiles are\u00a0carbon dioxide, nitrogen, ammonia, hydrogen, methane, sulphur dioxide and water which are abundant in nature and necessary to living organisms.<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1) What is\u00a0Aldehyde?<\/h3>\n<p>It is any of a class of organic compounds in which a carbon atom shares a double bond with an oxygen atom, a single bond with a hydrogen atom, and a single bond with another atom or group of atoms. The double bond between carbon and oxygen is characteristic of all aldehydes and is known as the carbonyl group.\u00a0<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/www.thehindu.com\/sci-tech\/science\/plants-danger-green-leaf-volatiles-fluorescence-new-study\/article67550984.ece\" target=\"_blank\" rel=\"nofollow noopener\"><u>Plants warn each other of danger, and now we can watch them | Explained<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Green Leaf Volatiles (GLVs) consist of six carbon (C6) compounds including alcohols, aldehydes and esters and are released from almost every plant.<\/p>\n","protected":false},"author":5,"featured_media":17510,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-17509","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/17509","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=17509"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/17509\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/17510"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=17509"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=17509"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=17509"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
