A sunflower is a plant! Plants are amazing living things that can make their own food through a process called photosynthesis. Unlike animals, plants do not eat other living things. Instead, they use energy from the sun, carbon dioxide from the air, and water from the ground to create their own food. Plants come in all shapes and sizes – from tiny blades of grass to huge oak trees.

The roots have two main jobs: they anchor (hold) the plant in the ground so it does not blow away, and they absorb (take in) water and nutrients from the soil. Nutrients are like vitamins for plants – they help the plant grow strong. Some roots we eat, like carrots, potatoes, and radishes!

The stem supports the plant and acts like a transportation highway. Water and minerals travel upward from the roots through the stem to the leaves. Food made in the leaves travels downward through the stem to the roots. Some stems we eat, like celery and asparagus. Tree trunks are actually stems – just very thick, woody stems!

Leaves need sunlight, carbon dioxide, and water to make food. This process is called photosynthesis – which means "putting together with light." The leaf uses energy from the sun to turn carbon dioxide and water into sugar (food for the plant) and oxygen (which we breathe!). That is right – plants give us the oxygen we need to live!

The main job of a flower is to make seeds. Seeds grow into new plants, so flowers help plants reproduce (make more of themselves). Flowers attract pollinators like bees, butterflies, hummingbirds, and bats with their bright colors and sweet smells. When a bee visits a flower, pollen sticks to its body and gets carried to the next flower – helping the plant make seeds!

Plants need sunlight to make their own food! Without sunlight, a plant cannot perform photosynthesis and will eventually die. That is why plants grow toward windows and why trees in the forest grow tall – they are reaching for the sun. Plants also need water (without it, they dry out), air (for carbon dioxide), and soil (for nutrients like nitrogen and minerals).

The first thing to come out of a seed is the root (called a radicle). It grows downward because of gravity – it is trying to reach the water and nutrients in the soil. Then the stem (called a shoot) grows upward toward the light. The stem carries the first leaves up into the sunlight so the plant can start making its own food. This process of a seed starting to grow is called germination!

Plants give us oxygen to breathe! During photosynthesis, plants take in carbon dioxide (which we breathe out) and release oxygen (which we need to breathe in). That is why forests are called the "lungs of the Earth." Plants also give us food like apples, carrots, rice, and wheat. Without plants, animals (including humans) could not survive. We need plants, and plants need us to protect them!

Evergreen trees stay green all year! Their leaves are usually needle-shaped and have a waxy coating that helps them hold onto water during cold winters. Deciduous trees lose their leaves in the fall to save water and energy during winter. In the spring, they grow brand new leaves. That is why you see bare trees in winter – they are deciduous!

A seed is the first stage of a plant's life! Inside the seed is a tiny plant called an embryo. The seed also has stored food to help the baby plant grow until it can make its own food through photosynthesis. When conditions are right (water, warmth, air), the seed germinates and a new plant begins to grow. That is the amazing circle of plant life!
