Solution

In Avicennia, the pneumatophores show negative geotropic movement, meaning they grow upward against gravity. These are special aerial roots that project above the soil or water surface in marshy areas. Their main function is to help in respiration by absorbing oxygen through small openings called lenticels, allowing the submerged parts of the plant to breathe in waterlogged conditions.
