A broad, flat structure of a plant that traps light energy for photosynthesis.
A waxy waterproof coating.
Do not have vascular tissues.
Plant organ that absorbs water and nutrients from the soil.
Contains an embryo, along with a food supply, covered by a protective coat.
Provides structural support for upright growth and contains tissues for transporting foods.
Have vascular tissues.
Made up of tubelike, elongated cells through which water, food, and other materials are transported
Scaly structures that support male or female reproductive structures

Includes sperm cells, nutrients, and a protective outer covering.
Found at or near the tips of roots or stems
Long cells with unevenly thickended cell walls
Producers a tough covering for the stem and roots
Composed of flattened parenchyma cells that cover all parts of the plant.
Regions of actively dividing cells.
Made up of a series of tubular cells
Most abudant kind of plant cells
Have very thick and rigid walls.
Openings in the cuticle of the leaf
Produces new xylem and phloem cells in the stems and roots
Tubular cells that transport water throughout the plant
Plant tissue composed tubular cells
Single layer of cells that forms a waterproof seal

Leaflike structures arranged in a circle around the top of a flower stem
The female structure of a flower
Leaflike and encircle the flower stem beneath the petals
Male reproductive structure
The period of inactivity in a mature seed
The food storage tissue that supports development of the embryo
The beginning of development of embryo into a new plant.
