Answer 1

Answer:

Types of stem

Four types of stem

1) Herbaceous stem

2)woody stem

3)

Explanation:

Many plants are annuals and complete their life cycles in one growing season, after which the entire plant, including the stem, dies. In biennial plants the lower part of the stem, often modified for food storage, persists after the first growing season and bears buds from which an erect stem arises during the second growing season. In perennial plants the short stem may produce new shoots for many years. Plants producing woody stems are called trees and shrubs; the latter produce branches from or near the ground, while the former have conspicuous trunks.
