Q1: What are the two kinds of stem?

[Answer]

A stem has two main purposes. It supports other parts of the shoot and it transports materials through the plant.

There are two kinds of stems:

1. Soft stalks which die at the end of the growing season, and

2. Woody stems like trunks which survive from year to year.
