    Root Cap

    The protective structure covering the tip of the root, aiding soil penetration.

    Mucilage

    A gelatinous mixture secreted by root cells made of polysaccharides that aids in root movement through soil.

    Mucigel

    The mixture of mucilage, microorganisms, and soil particles, aiding root lubrication and interaction.

    Zone of Cell Division

    The area where the apical meristem is located, actively producing new root cells.
