Monilophytes life cycle
WebIn bryophytes, the dominant phase is represented by a gametophytic plant. The gametophyte is independent, photosynthetic, thalloid phase. Antheridia and archegonia are formed on the gametophyte. These organs are multicellular. These organs bear the respective gametes, that is male and female gametes respectively. The antheridium … WebLe système endocannabinoïde, au sens large, comprend : Les lipides endogènes à base d'arachidonate, l'anandamide ( N- arachidonoyléthanolamide) et le 2-AG ; ceux-ci sont appelés « endocannabinoïdes » et sont des ligands physiologiques pour les récepteurs cannabinoïdes. Les endocannabinoïdes sont tous des eicosanoïdes .

The diploid sporophyte produces two types of spores. In angiosperms, however, these can be born by the same structure (perfect hermaphroditic flowers), or different flowers on the same plant (monoecious) or on different plants (dioecious).
