Difference between herbs, shrubs and trees?

Herbs, shrubs, and trees are three types of plants categorized based on the size and the branching pattern of each plant. The main difference between herbs, shrubs and trees is that herbs have soft, non-lignified, un-branched stems while shrubs have woody, immediately branched, multi stems and trees have woody stems that grow upright for about a meter before branching. Since shrubs and trees are somewhat similar to each other, they are always lumped together. Banana, basil, tulsi, lettuce, and coriander are examples of herbs. Shrubs are taller than herbs. Rose and lemon are examples of shrubs. Trees are the tallest plants. Mango, coconut, and Banyan are examples of trees.
