How Does the Stem Help a Plant Grow?

The stem is very important for a plant because it holds the plant up and helps it grow tall. The stem also carries water and food from the roots to the leaves, flowers, and fruits so they can stay healthy.

Example: When you water a plant, the stem takes the water up from the ground and sends it to the leaves, which helps the plant grow strong and green.

Fun Fact: Some plants have very thick stems, like trees, which can help them stand up tall and support their big branches!
