The common types of complex permanent tissue are: Xylem (or wood) Phloem (or bast). Xylem and phloem together form vascular bundles.
The epidermis is the outermost cell layer of the primary plant body.

Aerenchyma or aeriferous parenchyma [1] or lacunae, is a modification of the parenchyma to form a spongy tissue that creates spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root.
