Lichen Structure And Types — a labelled NEET Biology diagram with a definitions lexicon.
Lichen Structure and Types Labelled parts: Fungus, Alga, Upper Cortex, Algal Zone, Algal Cells, Medulla, Fungal Hyphae, Lower Cortex, Rhizines, Crustose, Foliose, Fruticose. The photosynthetic component (often cyanobacteria or algae) found within symbiotic organisms, such as lichens or coral polyps. FYI: In lichens, the photobiont (e.g., Nostoc ) provides energy through photosynthesis, while the mycobiont (fungus) provides structure and protection. A layer of the inner ear (cochlea) containing sensory receptors (hair cells) responsible for detecting sound vibrations and converting them into electrical signals. FYI: Damage to the lower cortex, particularly the sensory hair cells, often leads to permanent hearing loss. A type of lichen that grows in a hard, crust-like layer tightly adhered to the substrate (e.g., rock or bark). FYI: Crustose lichens are the most common type and are often found on exposed surfaces, indicating high tolerance to environmental stress. A type of lichen that grows in leaf-like lobes or patches, often peeling away from the substrate. FYI: Foliose lichens are characterized by their distinct, often ruffled, leaf-like structures, making them easier to observe than crustose types. A type of lichen that has a shrubby, branching, or tufted appearance, often resembling miniature bushes. FYI: Fruticose lichens are the most three-dimensional type, growing in pendulous or bushy masses, which helps them colonize diverse habitats.
