onion plants
According to the Guinness book of world records the world’s largest potato grown was 7 pounds 1 ounce by J.East (1953) and J.Busy (1982) of Great Britain. Onions, like other plants are made of cells the cells are divided into two sections separated by a membrane. One side of the membrane contains an enzyme. The other side of the membrane contains molecules that contain sulphur. When you cut an onion the contents on each side of the membrane mix and cause a chemical reaction. This reaction produces molecules such as ethylsufine which make your eyes water. The water hyacinth or Eichhomia crassipes grows vegetatively via offset which is a modified stem. This plant is extremely viable and fast growing. Even if a small portion of offset remains, it can grow within a short time to produce hundreds of new plants. The beautiful Hussain Sagar Lake in Hyderabad once got covered with waterhyacinth completely, choking all the water. Only after treating it with weedicides several times, the hyacinths could be removed permanently. In Sensevieria trifasciata or the snake plant, leaf cuttings instead of stem are used to produce a new plant. Gymnosperms cannot be propagated by stem cuttings because they do not have the potentiality to initiate rooting even when treated with auxin.
