Usage: primarily botanical and mycological; technical term used in plant science and soil biology

Examples

• The arbuscles formed by the mycorrhizal fungi help the plant absorb nutrients from the soil.
• Under the microscope, the arbuscles appeared as delicate, branching structures inside the root cells.
• Arbuscular mycorrhizal fungi develop arbuscles that increase the plant's access to phosphorus and other minerals.
• The presence of arbuscles indicates a healthy symbiotic relationship between the fungus and the plant root.
