So, the correct answer is option (d). Seedless vascular plants (lycophytes, ferns, and horsetails) have two major adaptations compared to nonvascular plants: true roots and vascular tissue. The primary cell wall (PCW) has many essential biological roles, ... GalA was also present at higher concentrations in charophytes and bryophytes than in vascular plants. Because they have no vascular tissue, they aren’t able to take water from the soil and transport it to higher tissue. Bryophytes need wet and often well shaded environments which deliver a lot of rain water for them to soak up. the difference between vascular and non vascular plants are ferns and their relatives share two characteristics they have vascular tissue and use spores to reproduce. Most moss gametophytes do not have a cuticle and are 1-2 cells thick. have stomates fixed in the open position; they cannot be closed release flagellated sperm directly into the environment (and so need water--at least a thin film--for reproduction) have a dominant gametophyte generation, and a short-lived, ephemeral sporophyte Bryophytes that lack true vascular tissue do not have true leaves, stems and roots. Unlike angiosperms, non-vascular plants do … The vascular tissues in the more advanced ferns and "fern allies" are made up of xylem and phloem, which conduct water, nutrients, and food throughout the plant body. Charophytes do not consider to be a part of the Plantae kingdom because all plants are multicellular and contain vascular tissues; whereas, all members of the Charophytes are not multicellular and lack any vascular tissue. The living lycophytes are all small and herbaceous, whereas the extinct lycophytes included large trees, which were important in the formation of coal. Vascular tissue is found in more “complex” plants. Bryophytes don't have specialized tissue to transport food and water through a larger plant. are broad leaves with several strands of vascular tissue; are narrow and have a single strand of vascular tissue: D) are narrow and have a single strand of vascular tissue; are broad leaves with several strands of vascular tissue: 12: The fern life cycle: A) all of these choices accurately describe the … 2. Submit a question and get it answered by experts! ... 2.2.3 Charophyta (Migula, ... along with complex multicellular tissue and a variety of adaptations to life on land (Delwiche & Cooper, 2015). This lack of vascular tissue keeps them small because: 1. The evolutionary situation of a grade would have some members of the group having the trait, others not. Non-vascular plants, or bryophytes, include the most primitive forms of land vegetation.These plants lack the vascular tissue system needed for transporting water and nutrients. This morphology, having only one vein which does not branch, is unique to the lycophytes, and these leaves are given the name microphylls . leaves which have only a single strand of vascular tissue, are thought to have evolved from a small stem outgrowth or flap, into which a strand of vascular tissue grew. This lack of vascular tissue keeps them small because: 1. The above innovations in the charophyte algae can be directly tied to the transition to multicellularity in the streptophyte lineage. Because they have no vascular tissue, they aren’t able to take water from the soil and transport it to higher tissue. The thin stem would have been better suited for photosynthesis and gas exchange than do lycophytes have vascular tissue - question answered here at HaveYourSay.org - leading question and answers website. Besides not having vascular tissue, what do they all have in common? The lycophytes, which compose the phylum Lycophyta, are one of four phyla of seedless plants having vascular, or conducting, tissue. Option (d) charophytes are multicellular organisms that lack vascular tissue. Like the vascular plants, bryophytes do have differentiated stems, and although these are most often no more than a few centimeters tall, they do provide mechanical support. However, green algae, which also have cellulose in their cell walls and have chloroplasts that perform photosynthesis, are sometimes grouped with plants. These adaptations allowed seedless vascular plants to outcompete nonvascular plants in early colonization of life on land. ... and with the acquisition of vascular tissue and upright habit. Today, most modern-day algae are classified as bacteria, not plants. The evolutionary situation of a grade would have some members of the group having the trait, others not. Plants are believed to have evolved from algae-like ancestors. Charophytes do not have multicellular sporangia, and their flagellated water-dispersed spores lack sporopollenin. Although some mosses have quite complex water-conducting vessels, bryophytes lack true vascular tissue. The leaves of the Lycophyta each have a single unbranched vein, or strand of vascular tissue, which supplies the leaf with water and distributes manufactured nutrients to other portions of the plant.
