Parts of a plant

Questão	Responda
woody tissue	This is usually found in the center of the stem. It is made of layers of xylem (carries water). This is what lets plants get tall. Image: woody (image/jpeg)
seed	You know, a baby plant. Both angiosperms and gymnosperms produce seeds. Image: 600px-Brown_Flax_Seeds (image/jpg)
cuticle	a waxy coating that limits water loss from leaves (in this picture, the cuticle is actually keeping water from entering the leaf) Image: 500px-Kale2 (image/jpg)
stoma	Little holes on the bottom of leaves. They let gas in (CO2) and out (O2). (In deference to the trypophobes, I'm not going to include some gnarly pictures of the little stoma holes on the underside of a leaf)
guard cell	These open and close the stoma. Like guards who open and close a door, they control when gases are exchanged.
rhizoid	So these are little hair-like, root-like structures. They aren't roots, because rhizoids are only a single cell. They aren't hairs because duh. They are only found in non-vascular plants.
parallel venation	The veins on the leaf are... parallel. The tricky part to remember is that this pattern is typical in angiosperms that are monocots. Image: parallel (image/png)
