Answer

Adventitious roots arise from any part of the plant body other than the radicle. They may develop underground or aerially, and they occur in both dicots and monocots. Examples include ivy, mangroves, …

Answer

Answer

A typical root has four main regions: root cap, meristematic zone, zone of elongation, and zone of maturation. The meristematic zone is about 1 mm long, the zone of elongation is about 4-8 mm long, an…

Answer

Most plants have a simple root cap, but Pandanus has a multiple root cap. In hydrophytes like Pistia and Lemna, a root pocket replaces the root cap.
