germ plants begin life as an embryonal plant inside the covering of a seed . When water , the ejaculate germinates and as it begins to rout and flower , it can produce new seeds . The two major category of seed plants are angiosperm ( with covered seeds ) and gymnosperms ( naked semen ) .
Angiosperms/Flowering Plants
" Angiosperms are essential for human macrocosm ; the vast majority of the world ’s crop are angiosperm , as are most born clothing fibers . Angiosperms are also sources for other important resources such as medicine and tone , " says Tolweb.org . They also state that 132 million days ago , a variety of angiosperm , both lowly and large were around , like to magnolias .

Gymnosperms/Non-flowering Plants
Flowerless seed plants are called gymnosperm . " conifer are common gymnosperms ; or else of blossom , conifers have strobilus that produce pollen or eggs , " say Teachersdomain.org .
" The existence and human civilisation would be very different if there were no pines , redwood , spruces , and other gymnosperms . These Sir Herbert Beerbohm Tree form blanket forests in many cool and colder regions of the world . These forest provide lumber for trillion of homes , forest for many other uses , most of our newspaper , and home ground for many species of wildlife . These forests ameliorate the air we pass off , producing oxygen and storing C dioxide , " says Margaret Connolly and Christopher Campbell , University of Maine .

Are All Plants Alike?
Not all plants are cum plants ; mosses and fern procreate with spores that later develop into new plants . harmonise to Teachersdomain.org " Unlike seminal fluid , spores are grow without fertilisation and carry neither a industrial plant fertilized egg nor endosperm . Some works can regurgitate without spore or seeds through vegetative replication , in which a part of the stem or root give rise to a novel plant life . "
