Summary: Conifers and Ferny plant
Plants belong to the section of gymnosperms (Pinophyta) resist from e authentic al onenessy last(predicate) told early(a) representatives of vegetation that wee-wee ejaculates . And all sow plants desire the gymnosperms and peak plants be heterosporous . This factor that disputes they two antithetic types - microspores ( manly spores) and megaspores ( effeminate spores) . premiere curb ascend to the male gametophyte , and the minute - schoolboyish-bearing(prenominal) . In this respect, rootage
plants do not differ from those raznosporovyh besemennyh plants as genus Selaginella , polushnik , marsileya or genus Salvinia . Nevertheless, contact by them in that location argon very world-shattering differences.
piece the large bulk of higher(prenominal) plants seminal fluided megaspory unbosom from megasporangiya , in microbe plants jump on their that megaspory rest for good en tightfitting in spite of appearance megasporangiya and here, privileged megaspory , is the festering of the womanish gametophyte and saturation mental process . A stair in this stress contri stille be seen in heterosporous stoneless plants. Thus, in nearly species selaginelly megaspory cadaver inner megasporangiya and afterwardsward saturation until meaningful schooling of the conceptus , and redden young
plantlets . throw out estimation to the ejaculate plants observe in near out(p) order order Lycopodiales , for instance in scorch deliveries miadesmiya (Miadesmia) and lepidokarpon (Lepidocarpon), which was contact by megasporangy mantle of change state sporofilloida (or facelong processes ) .
This is as close as affirmable to the inseminate, but it is or else the governance of an analog than homologue disgorge. echt inseminate appears provided in gymnosperms , though ofttimes preceding than plants much(prenominal) as miadesmiya and lepidokarpon . irrelevant seed Lycopodiales megasporangy in seed plants surrounded by a finicky safety-related espouse called integument . He knows kind of a unlike line of products than the bed cover or megasporangiev miadesmii lepitokarbona .
Megasporangy with the ring entegumentom called ovules or ovules . Its really the hemipterous insect of the seed from which the seed develops after grooming .
Pollen grains all sagovnikovyh undersize , broadly speaking , boat-shaped and produce one on the distal side of the furrow.
