Although there are plenty of plants in various sizes, colours and hues, the parts of the plants can be split mainly into
  1. Stem
  2. Leaf
  3. Root and
  4. Flower
Stem is the strongest part of the plant that helps water and mineral movement vertically upwards to all other parts of the plant.
The following are the main functions of the stem:
  • Acts as a structural support system to a plant.
  • Aids in the movement of minerals and water to the leaves as well as other parts of the plant.
  • Transports prepared food from leaves to the other parts of a plant.
  • Stem bears the plant parts - leaves, branches, buds, flowers, and fruits.
In trees, the stem is called the trunk, which is strong, and covered by bark (tough outer layer).
