These are the spaces between plant cells where the cell walls do not quite come together. Intercellular spaces are probably most easily observed in parenchyma tissue where the cells are roundish, leaving many small spaces between the cells. In the spongy parenchyma of the leaf mesophyll, these intercellular spaces have the special name of substomatal chambers because the spaces are so large.
Inferior ovaries have the flower parts (calyx, corolla, and androecium) attached above the ovary to the top of the ovary. Epigynous and inferior ovary are synonymous terms.

The integument is composed of two layers of cells and when mature, makes up the seed coat. It starts out as two layers of cells that grow out from the nucellus in the developing seed.
Intercalary growth is grow due to the activity of the intercalary meristem. Intercalary meristem is meristem at the base of the internode in monocot stems (particularly in grass stems).
Intercalary meristem is meristem at the base of the internode in monocot stems (particularly grass stems). Only the apical meristem is active. If the tip of the stem is removed, the uppermost intact intercalary meristem becomes the apical meristem and starts intercalary growth.

Interfascicular cambium is vascular cambium derived from the de-differtiated parenchyma cells of the pith ray. Thus, the parenchyma cells of the pith ray between two vascular bundles de-differentiates into meristem tissue. This is called interfascicular cambium.

Irises are monocots that are in the family Iridaceae in the division Anthophyta. They have inferior ovaries and regular flowers. The genus Iris has all of its flower parts petaloid (texture and color of petals). Irises produce a rhizome that becomes the perennial part of the plant.

Isodiametric is a word that describes parenchyma cells. "Iso" means same and diametric has to do with the dimensions of the cell. Thus, isodiametric literally means "same dimensions." The dimensions of the cell are the length, width, and height. Thus, it means that the length, width and height are approximately equal in each of the parenchyma cells.
