Question

What are coralloid roots?

Answer 1

Hint: Roots are the significant underground part of every single vascular plant. This part of the plant is responsible for mooring the plant down into the ground and absorbing the fundamental mineral components, supplements, and water from the dirt to be able to provide the plant. It is likewise used to store food.

Complete answer:
Coralloid roots are specific roots found in Cycas which are related to nitrogen-fixing cyanobacteria. Inside the coralloid root is the cyanobacterial zone, which is the locale possessed by cyanobacteria. The coralloid roots contain Cyanobacteria, which has a blue-green growth that fixes nitrogen and, in relationship with root tissues, produces advantageous amino acids such as asparagine and citrulline. Coralloid roots of cycads were found to start endogenously from the pericycle of apogeotropic optional roots or extrinsic roots that have been to the surface of the soil. All of the developed coralloid attachments are defenseless to diseases caused by algal endophytes, which appear to enter from the soil through a break in the dermal layers. In the coralloid roots, the green growth possesses intercellular spaces in a zone that emerges from the protoderm, and in which the cells prolong radially following algal disease. The zone is encircled by a determined root cap. The secondary cortex is derived from the root cap.

Note:
The coralloid roots develop blue-green algae that help in nitrogen fixation. Nitrogen fixation is a process by which molecular nitrogen is converted into ammonia that is further used by the plants and microorganisms in their metabolic processes.
