Plant Life Cycle

SeedsGerminationStems and RootsLeavesFlowersPollination

The plant life cycle begins with a seed. The seed will sprout and produce a tiny, immature plant called a seedling. The seedling will grow to adulthood and form a mature plant. The mature plant will reproduce by forming new seeds which will begin the next life cycle.

Why does Poison Ivy Cause a Rash ?


  • Poison Ivy rash is caused by an oily resin called urushiol, found in the leaves, stems and roots of poison ivy, poison oak and poison sumac.
  • Urushiol is very sticky, so it easily attaches to your skin, clothing, tools, equipment or pet’s fur. You can get a poison ivy reaction from direct touch, touching contaminated objects, and inhaling smoke from the burning plants.
  • A poison ivy rash itself is not contagious.
