Casuarina is a member of the family, characterized by drooping equisteoid twigs, are evergreen, and monoecious or dioecious. The roots have nitrogen fixing nodules that contain the soil actinomycetes called Frankia which is filamentous bacteria.
Which one of the following is the is a flowering plant with nodules containing filamentous nitrogen fixing microorganisms?
Casuarina equisetifolia is a flowering plant with nodules containing filamentous nitrogen-fixing microorganisms.
Which of the following flowering plant has nodules?
Nodules are produced by the roots of Casuarina equisetifolia where bacteria fix atmospheric nitrogen, which is a key element for the plant’s growth and their metabolism. Hence, the correct answer is option (B).
Which one of the following is flowering plants?
Pine and Banyan are flowering plants i.e, flowers are present in these plants whereas Moss and Fern are non-flowering plants i.e, flowers are absent in these plants.
Which have nodules containing nitrogen fixing bacteria?
Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation. Rhizobia bacteria convert nitrogen gas (N2) to ammonia (NH3) in a process called nitrogen fixation.
Which of the following is a flowering plant with nodules containing filamentous nitrogen?
The Casuarina tree has nitrogen fixing root nodules that harbor a filamentous streptomycete like nitrogen fixing organism called Frankia.
Is fern a flowering plant?
Ferns are plants that do not have flowers. Ferns generally reproduce by producing spores. … However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.
Which of the following is incorrect about nitrogen fixation in nodule?
It is an energy requiring process. Mg is required as cofactor for nitrogenase enzyme. Process uses atmospheric nitrogen but not atmospheric hydrogen directly.
Is mushroom flowering plant?
Mushrooms aren’t plants, they are fungi. … Flowering plants reproduce with seeds. -Fungi have cell walls made of chitin.

What are the nitrogen-fixing plants?
Plants that contribute to nitrogen fixation include the legume family – Fabaceae – with taxa such as clover, soybeans, alfalfa, lupins, peanuts, and rooibos.
Which bacteria fixes nitrogen in leguminous plant?
Legumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant.
