<human>: Is there a way to tell how old a plant is?
<bot>: Yes, there are several ways to tell how old a plant is. One way is to look at the number of leaves and branches it has. Another way is to examine the stem of the plant. If the stem is thick and woody, then the plant is likely older than if it has thin, flexible stems. You can also check for signs of aging such as yellowing or browning of foliage and discoloration of the stem.
