Diversity in the Living World

Plants differ

A tulsi plant sits in a pot. A mango tree stands in the yard. Is each a herb, a shrub or a tree?

Loading lab…

Herb — a soft, green stem.
Step 1 of 4
  1. Herb — a soft, green stem.
  2. Shrub — several woody (hard, like wood) stems, low down.
  3. Tree — one thick trunk, high branches.
  4. The stem decides. Height does not.

The rule

Tulsi is a herb and mango is a tree. Feel the stem first. Then look at the branches.

A herb is a plant with a soft, green stem.

A shrub has several hard stems, low down.

A tree has one thick trunk and high branches.

Woody means hard, like wood.
