The Plant Life Cycle!

3rd grade

A life cycle shows how a living thing grows and changes. While plants life cycles keep going, a plant’s life begins with the seed. With water, right temperature and right location, the seed grows.  It becomes a seedling. Roots push down into the ground to get water and minerals.  The stem reaches for the sun, and leaves begin to unfold. A bud appears.  The plants then produce flowers. The flowers  are then pollinated in many ways – by bees, moths, butterflies, insects, moths, bats, butterflies and even by the wind. The pollinated flower turns into fruit. The new seeds are inside the fruit.  The ripe fruit drops to the ground and the cycle begins again.



Some seeds have an outer layer called a seed coat, which provides protection and food for the seed. When a seed grows, a small root begins to grow downward and a shoot grows upward. When the shoot hits the surface, the plant is called a sprout. The sprout uses water and nutrients from the soil along with sunlight and air to grow and change into a seedling.


A seedling is a small plant with few leaves. Later the seedling changes into a young adult plant.

Young Adult Plant:

At this stage, the plant is bigger and may have more leaves. Thin branches will develop on young adult trees. Over time, the young adult plant will grow into an adult plant.


Adult Plant:

The adult plant is now mature and has the ability to reproduce through spores or flowers. After flowers are pollinated, they get bigger and turn into fruit with seeds inside. The fruit protects the seeds and after it ripens, the seeds can start the life cycle all over again. Because there are so many threats to both seeds and seedlings, sometimes a plant will make a lot of seeds so it will survive.

Watch the seed grow!

All plants need plenty of water and light to grow into healthy plants!
*don't over water or give too much light to plants*
