Clover peas lupins.
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
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.
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.
They have nodules on the roots which has nitrogen fixing bacteria
Soya bean root nodules containing billions of Brady rhizobium bacteria.Rhizobium leguminosarum was identified 1889.The order Rhizibiales has bacteria in their roots.
There's tons of types of bacteria and tons of types of plants. not all bacteria help plants (in fact, many bacteria hurt plants), and not all plants can be helped by bacteria. it would be almost impossible to list every bacteria that helps plants, but one example would be the denytrifying bacteria that live on the roots of most legumes (plants such as peas, beans, and peanuts). these bacteria convert nitrogen from the soil (that gets into the soil when animal carcases rot or when lightning strikes the ground). Legumes can't use pure nitrogen. these bacteria combine it with oxygen and make it NO2 or NO3, which are both forms of nitrogen that plants can use. once the plant is done using the NO2 or NO3, different types of bacteria (called denitrifying bacteria) will convert the NO2 and NO3 back to pure nitrogen and put it back into the atmosphere where it can be used by other organisms. these are just two of the millions of types of bacteria in God's creation, but they are extremely helpfull to plants.
Desert plants are known to have taproots. With these types of roots there are two components which consist of the primary root and secondary lateral roots. These types of roots can also be found on dandelions, carrots, radishes, potatoes, and beets.
one is the gymnosperm phyla Cycad
Algae and mosses are two examples of plants that can lack true stems, roots, and leaves. These plants typically have simple structures that allow them to absorb nutrients and carry out photosynthesis.
