By persistent apices. Leaf arrangement. During the gametophyte stage, haploid gametes (male and female) are formed in the specialized sex organs: the antheridia (male) and archegonia (female). Most seedless vascular plants are homosporous, which means they produce only one type of spore, and that spore will grow into a gametophyte that has both male and female sex organs. Materials and methods: After exposure to 10 M of the compounds for 24 h, cell cycle and cell survival analyses were performed using FACS and MTT assay to confirm the effect of these bisbibenzyls on PCa LNCaP cells.

Non-Vascular Plants: Characteristics, Types and Species However, ferns use asexual methods to reproduce, too. It is estimated that there are about 9000 species of liverworts. protists, Seedless vascular plants are early vascular plants that contain a number of adaptations that helped them survive life on land. Being the earlier vascular plants, they could grow tall with support from their vascular tissue and had little competition from seed plants, which were still evolving. They were the dominant species in ancient forests, consisting of nonvascular mosses and seedless ferns, horsetails, and club mosses. All of the following are considered evolutionary advantages of seeds except: they provide an additional site of nutrient synthesis for the parent plant. The group's common name "hornwort" refers to the tall narrow sporophytes which are embedded in the top of the plant.
