Fibrous root
This is the organization of roots from the base closest to the plant itself to the tip of the root: zone of maturation - cells specialize to carry particular functions (root hairs present) zone of elongation - rows of newly produced cells elongate zone of cell division - new cells being produced root cap - covers the growing tip
The zone of elongation occurs when the cells in this zone stretch and lengthen as small vacuoles within the cytoplasm coalesce and fill with water. One or two large vacuoles occupy almost all of the cell volume in fully elongated cells. Cellular expansion in this zone is responsible for pushing the root cap and apical tip forward through the soil.

No a grain of rice is not a root.
Root hairs are present in root hair zone. Root hair zone is located just above the root merestem zone.
the sqare root of rice is grainfart.
neritic zone
The aphotic zone is formally defined as the depth beyond which less than 1% of sunlight penetrates.
it is the open ocean. it is everything
