The main photosynthetic organs of vascular plants.
A tiny extension of a root epidermal cell, growing just behind the root tip and increasing surface area for absorption of water and minerals
A main vertical root that develops from an embryonic root and gives rise to lateral roots
A root that arises from the pericycle of an established root.

The outer protective covering of plants.
The dermal tissue of non-woody plants, usually consisting of a single layer of tightly packed cells.
A waxy covering on the surface of stems and leaves that prevents desiccation in terrestrial plants.
Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body
Vascular plant tissue consisting mainly of tubular dead cells that conduct most of the water and minerals upward from the roots to the rest of the plant.
Vascular plant tissue consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant
Plant tissue that is neither dermal nor vascular, fulfilling a variety of functions , such as storage, photosynthesis and support
