How Internal Structures Help Plants Survive

Plants have special parts inside them that help them stay alive. These internal structures—parts you cannot always see from the outside—work together to help plants survive, grow, and make new plants.

One important internal structure is the transport tubes. These tiny tubes run through the stem like straws. They carry water from the roots up to the leaves and move food from the leaves to other parts of the plant. Without transport tubes, water and food could not reach where they are needed, and the plant would die.

Inside the leaves are special leaf cells that capture energy from sunlight. These cells use the sunlight, along with water and air, to make food for the plant. This process gives the plant energy to grow. Without leaf cells making food, the plant would starve.

Flowers have internal parts that help plants reproduce. The flower parts work together to make seeds. Seeds contain baby plants and stored food. Each seed has protective coverings and a tiny plant inside. These seed structures keep the baby plant safe until it is ready to grow.

All of these internal structures are necessary for plant survival. Without transport tubes, leaf cells, flower parts, and seed structures, plants could not get food and water, make energy, or create the next generation. Each structure has an important job that helps the plant live.
