All plants are of same size. Do you agree?
No, different plants are of different sizes.
Plants can be classified into three types according to their size, i.e. herbs, shrubs, and trees.
Herbs: These are tender and green-coloured stem plants that are small in size and exhibit very less branching.
Shrubs: These are bigger than the herbs and have harder stems and branches.
Trees: These are essentially very tall with much thicker stems compared to shrubs but have branches on the upper part of the plant.
