Plant Life Cycle
Plant Life Cycle:

  • All plants start life as a seed.
  • The seed turns into a sprout when it grows roots.
  • The sprout becomes a seedling as grows a stem and leaves above the ground.
  • After the seedling becomes an adult plant it will grow flowers.
  • After the flowers finish blooming, each flower turns into a seed.
  • When the seeds fall down to the ground, the plant life cycle starts again.
  • Each seed can become a plant if it has the food, water and space that it needs to grow.
