On the basis of size and kind of stem, plants can be classified as herbs, shrubs, trees, creepers and climbers.
Herbs: They are usually short and have green and tender stems, which may or may not have branches like beet and carrot.
Shrubs: They have hard but not very thick stem. The stem
branches out near the base. China rose, henna and rose are shrubs.
Trees: They are tall and have hard and thick brown stem, which
branches much above the ground, for example, mango and neem.
Creepers: They have weak stems, so they cannot stand upright and spread on the ground, for example, bottle gourd.
Climbers: They too have weak stems. They take support and climb up, for example, money plant.
