Basic Facts

• The average plant goes through four stages:
  • seed, sprout, seedling, adult plant
• Seed
  • Through pollination (pollen reaches the stigma) and ferilization (the pollen and stigma join), a seed is formed.
  • Seeds are sometimes located in the fruit the plant produced.
  • Once the seed is in a suitable place, it begins to grow.
  • For the seed to go through germination, it needs three conditions: water, oxygen, and warmth.
  • Germination is when the seeds crack and the roots grow downward.
• Sprout
  • The next stage, the sprout, is when the shoot reaches the surface.
  • Sprouts take water and nutrients from the soil and sunlight and oxygen to grow.
• Seedling
  • Seedlings only have a few leaves.
  • Their leaves are vulnerable to many elements.
• Adult Plant
  • This last stage of a plant life cycle, the adult plant is fully mature.
  • Adult plants are able to reproduce.
  • Flowers are formed and the cycle repeats.
