当你徜徉于青山碧水间,欣赏郁郁葱葱的森林的时候,你可曾想到,这些树木已经在此存活了数百年,而其所经历的复杂进化历程可能已逾亿年。当你发现星星点点的苔藓在钢筋水泥之中顽强生长的时候,你可曾想到这些生命克服了多少风雨艰险,在这逼仄角落里进行着乾旋坤转、沧海桑田的巨变。当你大快朵颐的时候,你可曾想过,无论粗茶淡饭还是饕餮盛宴,大都是植物将太阳能转化、贮存,在发育和繁衍自身的同时,也为其他生物做出了奉献!正是多样而又神奇的植物,营造了我们赖以生存的环境。在地球生态系统中,有两类生物在生物圈的建立和发展中起着关键作用。一类是维管植物,另一类是人类。维管植物,特别是目前主宰
As you wander through the green mountains and admire the lush forests, you can recall that these trees have lived here for hundreds of years and the complex evolution they have experienced may have been more than 100 million years. When you find the dotted moss in the tenacity of steel and concrete in the growth, you can think of these lives to overcome the number of stormy, in this cramped corner of the spin, a sea of change. When you bite it, you may have thought that, regardless of crude tea or gluttonous feast, most of the plants will be solar energy conversion, storage, in the development and reproduction of their own, but also for other creatures made a dedication! It is diverse and amazing The plants that create the environment we live in. In the Earth's ecosystem, two types of organisms play a key role in the establishment and development of the biosphere. One is the vascular plant and the other is the human. Vascular plants, especially currently dominated
