- A rhizoid is a root-like structure found on non-vascular plants like mosses and liverworts.A rhizome is the bundle of stems that is partially underground and the roots form on in a vascular seedless plant like a fern.A rhizome absorbs water and minerals by producing rhizoids, which are unicellular hair-like structures grown off the rhizome, which absorb these.

Rhizobacteria Nitrogenase is an enzyme involved in nitrogen fixation and requires anaerobic conditions. Membranes within root nodules are able to provide these conditions. The rhizobacteria require oxygen to metabolize therefore oxygen is provided by a hemoglobin protein called leghemoglobin which is produced within the nodules.

Bryozoa The Bryozoa, also known as Polyzoa, Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals.Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a crown of tentacles lined with cilia.urrently there are about 5,000 known species of Bryozoa that are known. The Bryozoa are known as a moss animals. The different species can come together to form a colony that can attach to different kind of rock surfaces as well as shells and algae.

- Strongyloidiasis is an intestinal infection caused by 2 species of the parasitic nematode Strongyloides. The most common and clinically important pathogenic species in humans is S stercoralis (see the following image). S fuelleborni is found sporadically in Africa and Papua New Guinea.he life cycle of Strongyloides stercoralis is complex and unique among the intestinal nematodes. This worm has 2 types of life cycles—a free-living life cycle (rhabditiform larvae) and a parasitic life cycle (filariform infective larvae)—with 3 developmental stages: adult, rhabditiform larva, and filariform larva.

- Rhizobia are soil bacteria that fix nitrogen (diazotrophs) after becoming established inside root nodules of legumes (Fabaceae). In order to express genes for nitrogen fixation, rhizobia require a plant host; they cannot independently fix nitrogen.pecific strains of rhizobia are required to make functional nodules on the roots able to fix the N2. Having this specific rhizobia present is beneficial to the legume, as the N2 fixation can increase crop yield.

Rhizopus Rhizopus species grow as filamentous, branching hyphae that generally lack cross-walls (i.e., they are coenocytic). They reproduce by forming asexual and sexual spores. In asexual reproduction, sporangiospores are produced inside a spherical structure, the sporangium.ome Rhizopus species are opportunistic agents of human zygomycosis (fungal infection) and can be fatal.

- Overview: In media theory, rhizome is an evolving term that stems from the theories of Gilles Deleuze and Felix Guattari. It has been offered as an explanatory framework for network (both human and machine) theory and hypertext, although a strict reading of Deleuze and Guattari does not support these interpretations.he rhizome is reducible neither to the One nor the multiple...it is comprised not of units but of dimensions, or rather directions in motion.6 This inter-or trans-dimensionality is an important component of the rhizome, and separates it from a mere a system made up of components or structure made up of points.

Nonvascular Plants: Examples, Definition & Characteristics Instead of roots, nonvascular plants have rhizoids, which are small hairs that insert into the substrate to keep the plant in place. Vascular plants have roots not only for support but also to soak up water that is farther away from the plant.

rhizome In some plants (orchard grass, timothy), the rhizomes are short and the shoots that form on them above ground grow in a thick bunch. In others (reeds or couch grass), the rhizomes are long, grow rapidly, and branch. After the old parts of the rhizome die off, the underground shoots that have formed on it individuate (that is, vegetative reproduction occurs).

Clubmosses: An Ancient and Interesting Group of âFern Alliesâ Clubmosses, along with horsetails and ferns, have a primitive reproductive strategy. In many species of club mosses, club-like projections or “candles” held above the small leaved, conifer-like stems are known as strobili (strobilus, singular form) and have structures called sporangia (sporangium).

Iris  (plant) Iris is a genus of 260–300 species of flowering plants with showy flowers. It takes its name from the Greek word for a rainbow, which is also the name for the Greek goddess of the rainbow, Iris. Some authors state that the name refers to the wide variety of flower colors found among the many species.ris is the largest genus of the family Iridaceae with up to 300 species – many of them natural hybrids. Modern classifications, starting with Dykes (1913), have subdivided them. Dykes referred to the major subgroupings as sections.

Rhizopus These fungi are terrestrial and saprophytes or weak pathogens causing soft rots and molds. Members of this group also include parasites of insects, nematodes, mushrooms, and humans, as well as dung fungi. Members of the genus Rhizopus grow in soil and on fruits, other foods, and decaying organic materials.
