What are the 3 types of leaf veins?
VENATION
- PARALLEL: just like it sounds: The veins run parallel except where they meet at the tip and the base.
- PINNATE: secondary veins are spaced along a central midvein.
- PALMATE: several primary veins diverge from a point.
- PINNATELY LOBED: lobes are arranged on either side of a central axis, like a feather.
What is the function of main vein?
Veins have two main purposes. One purpose is to collect oxygen-poor blood throughout your body and carry it back to your heart. The other purpose is to carry oxygen-rich blood from your lungs to your heart. This is the only time veins carry oxygen-rich blood.
