Life Cycles of Plants

What is a Life Cycle?

Every living thing goes through a series of changes called a life cycle. Plants have a life cycle that helps them grow, make seeds, and start new plants.

Stages of a Plant’s Life Cycle

  1. Seed: Plants start as tiny seeds tucked into the soil.
  2. Germination: With water, warmth, and sunlight, the seed sprouts roots and a small stem.
  3. Seedling: The plant grows leaves and becomes stronger.
  4. Adult Plant: The plant grows flowers or fruit.
  5. Reproduction: Flowers make seeds, and the cycle begins again!

Why Are Plant Life Cycles Important?

Plant life cycles help us understand how food grows and how nature keeps going. The apples you eat and the flowers you see all come from these amazing cycles!

Fun Facts

  • Some seeds need special conditions to grow, like fire or cold weather.
  • Seeds can travel by wind, water, or by sticking to animals’ fur.

Explore the World

Watch a bean sprout in a wet paper towel or plant a sunflower seed and see the magic of life cycles in your own home!

Examples

  • A bean seed grows roots and leaves, then becomes a flowering plant.

  • An apple tree's flowers turn into apples that contain new seeds.

In a Nutshell

Plants grow from seeds, become seedlings, and then adult plants that make more seeds.

Key Terms

Germination
The process where a seed begins to grow into a new plant.
Seedling
A young plant that grows from a seed.
