Cycas। External morphology, Internal morphology of coralloid roots। B.Sc.bio.। by Surabhi ma'am

Welcome to the Biology Concept channel. External morphology refers to the study of the outer physical features of plants, including roots, stems, leaves, flowers, fruits, and seeds. These visible structures help in plant identification, classification, and understanding adaptation to the environment. One unique plant structure is the coralloid root, commonly found in Cycas. Coralloid roots are specialized roots that grow upward and form coral-like structures. They contain symbiotic cyanobacteria (blue-green algae) such as Nostoc and Anabaena, which fix atmospheric nitrogen. This adaptation helps the plant survive in nutrient-poor soils and plays an important role in ecological balance #ExternalMorphology #CoralloidRoots #PlantMorphology #Cycas #NitrogenFixation #Symbiosis #Gymnosperms #BotanyStudents #PlantScience #BiologyNotes #BScBiology #PlantAnatomy #EducationalPost #PlantAdaptations
