Stem

The stem is a part of a plant that serves several important functions. It supports the leaves, flowers, and fruits, and also transports water, minerals, and food throughout the plant. The stem is typically found above the ground, although in some plants, it may be underground.

Functions of the Stem

The main functions of the stem include:

• Support: The stem provides structural support for the plant, holding up the leaves, flowers, and fruits.
• Transport: The stem contains vascular tissues that transport water, nutrients, and food throughout the plant.
• Storage: Some stems, such as those of cacti, store water and nutrients to help the plant survive in arid conditions.

Types of Stems

Stems come in various forms, including:

• Herbaceous Stems: These are soft, green, and flexible stems found in non-woody plants such as grasses and flowers.
• Woody Stems: These are hard and rigid stems found in trees and shrubs, providing strong support for the plant.
• Modified Stems: Some stems are modified for specific functions, such as stolons (runners) for reproduction and rhizomes for underground storage.

Study Guide

Here are some key points to remember about the stem:

1. The stem supports the leaves, flowers, and fruits of a plant.
2. It transports water, nutrients, and food throughout the plant.
3. Stems can be herbaceous, woody, or modified for specific functions.
4. Understanding the structure and function of stems is important in understanding plant biology and horticulture.

Remember to observe different types of stems in plants around you and identify their unique features and functions!
