Nitrogen-fixing bacteria.
Nitrogen fixing bacteria are common in the roots of leguminous plants like Melilotus,Trigonella, ground nut etc. and some Gymnospermous plants like Podocarpus
Clover peas lupins.
Soya bean root nodules containing billions of Brady rhizobium bacteria.Rhizobium leguminosarum was identified 1889.The order Rhizibiales has bacteria in their roots.
Legumes do. Peas are a good example.
kylesupplement. Nitrifying bacteria would be one kind of bacteria.Legumes have them, and I think Beech trees (Nothofagus spp.) also do.These convert nitric acid or ammonia compounds to ones useful to the plant.
The two kinds of plant roots are taproots and fibrous roots. Taproots have a main central root that grows vertically downward, while fibrous roots are a mat of thin, branching roots that spread out horizontally. Taproots are common in dicot plants like carrots, while fibrous roots are common in monocot plants like grasses.
The two kinds of conducting tissues in plants are xylem and phloem. Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem transports sugars produced during photosynthesis to different parts of the plant.
The two kinds of meristems are apical meristem, located at the tips of roots and shoots, responsible for primary growth, and lateral meristem, found in the vascular cambium and cork cambium, responsible for secondary growth in plants.

Some bacteria living in symbiotic relationship in plant's roots fix gaseous nitrogen to ammonia. Also when plants or animals die, some bacteria decompose proteins to ammonia.
There are two ogranisms that are nitrogen fixers:Free-living (non-symbiotic) bacteria, which live in the soil. This includes the cyanobacteria (or blue-green algae) Anabaena and Nostoc and such genera as Azotobacter, Beijerinckia, and ClostridiumMutualistic (symbiotic) bacteria, which live live in nodules in the roots of plants. This includes Rhizobium,associated with leguminous plants, and Spirillum lipoferum,associated with cereal grasses.Nitrogen fixing bacteria are microorganisms present in the soil or in plant roots that change nitrogen gas from the atmosphere into solid nitrogen compounds that plants can use in the soil.
Kindsa of decomposers include: * bacteria * fungi * enzymes
