Stem: Functions, Structure, and Types

The main functions of stems are to support and elevation of leaves, fruits, and flowers. Stem arranges leaves in a way that it gets direct sunlight to perform photosynthesis. Xylem and Phloem conduct water across the plant. Stems stores food, water, and nutrients. Cells of a stem, meristems, produce new living tissues. Underground stem, Aerial stem, and subaerial stem are three different types of Stem. A stem has many important functions it performs other than letting you climb a tree. Let us take an in-depth look at the stem of plants.

A plant stem is one of the two main structural axes of a vascular plant. It is the part of the plant that lies above the ground. Few stems are also found underground and are considered to be stem modifications.

Functions of Stem

It supports and holds leaves, flowers, and fruits.

The stem allows the leaves to arrange in a way that they are able to receive direct sunlight in order to efficiently perform photosynthesis. The arrangement and position of leaves also allow for gas exchange.

The xylem and phloem present in the vascular bundles of stems conduct water and minerals across the plant.

Stems bear flowers and fruits in a position that facilitates the processes of pollination, fertilization, and dispersion of seeds.

Some stems undergo modification to store food and water. Example: succulents.

Few green stems contain chloroplasts and are capable of carrying out photosynthesis as well.

Some stems are modified to carry out vegetative propagation which is a form of asexual reproduction seen in plants.
