They can\u00a0sustain shrubs, trees,\u00a0walkways and benches with their\u00a0complex structural support,\u00a0irrigation, drainage, and root protection layers.\u00a0<\/li>\n<li>Extensive green roofs are relatively light. They support hearty native ground cover that requires\u00a0little maintenance. Extensive green roofs usually exist solely for their environmental benefits and don&#8217;t function as accessible rooftop gardens.<\/li>\n<\/ul>\n<\/li>\n<li>Benefits:\n<ul>\n<li>Green roofs\u00a0last longer than conventional roofs,\u00a0reduce energy costs with\u00a0natural insulation, create\u00a0peaceful retreats for people and animals, and\u00a0absorb storm water, potentially\u00a0lessening the need for complex and\u00a0expensive drainage systems.<\/li>\n<li>On a wider scale, green roofs\u00a0improve air quality and help reduce the Urban Heat Island Effect, a condition in which city and suburban developments absorb and trap heat.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2>Key Facts about Fungi<\/h2>\n<ul>\n<li>Fungi, along with Animalia (animals), Plantae (plants), Protista, Archaea\/Archaebacteria, and Bacteria or Eubacteria,\u00a0form the six \u2018kingdoms\u2019 of biology.<\/li>\n<li>They are\u00a0eukaryotic organisms, i.e., their cells contain membrane-bound organelles and clearly defined nuclei.<\/li>\n<li>Reproduction: Fungi usually reproduce both\u00a0sexually and asexually.\u00a0<\/li>\n<li>Distribution:\n<ul>\n<li>Fungi are either\u00a0terrestrial or aquatic, the latter living in\u00a0freshwater or marine environments.<\/li>\n<li>They are found in\u00a0all temperate and tropical regions of the world where there is sufficient moisture to enable them to grow.<\/li>\n<li>A\u00a0few species of fungi\u00a0live in the Arctic and Antarctic regions, although they are rare and are more often found living in symbiosis with algae in the form of lichens.<\/li>\n<\/ul>\n<\/li>\n<li>Importance of fungi:\n<ul>\n<li>They help in\u00a0breaking down dead organic material, they continue the cycle of nutrients through ecosystems.<\/li>\n<li>Fungi,\u00a0as food, play a role in\u00a0human nutrition in the form of\u00a0mushrooms.<\/li>\n<li>They also act as\u00a0agents of fermentation in the production of bread, cheeses, alcoholic beverages, and numerous other food preparations.<\/li>\n<li>Secondary metabolites of fungi are used as\u00a0medicines, such as antibiotics and\u00a0anticoagulants.\u00a0<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1) What is mycorrhiza?<\/h3>\n<p>Mycorrhizae are a symbiotic association between plant roots and fungi. Their major role is to enhance nutrient and water uptake by the host plant by exploiting a larger volume of soil than roots alone can do.<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/www.urbanscape-architecture.com\/wp-content\/uploads\/2018\/03\/Green_Roof_-_small.jpg\" target=\"_blank\" rel=\"nofollow noopener\"><u>Rich in fungi soil could benefit green roofs: Study<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Green roofs are ballasted roofs consisting of a waterproofing membrane, growing medium (soil), and vegetation (plants) overlying a traditional roof. <\/p>\n","protected":false},"author":5,"featured_media":19962,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-19961","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\/19961","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=19961"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/19961\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/19962"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=19961"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=19961"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=19961"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
