Keeping this in consideration, what are the different stages of germination?

The Seed Germination Process

  • Step 1: Imbibition: water fills the seed.
  • Step 2: The water activates enzymes that begin the plant's growth.
  • Step 3: The seed grows a root to access water underground.
  • Step 4: The seed grows shoots that grow towards the sun.
  • Step 5: The shoots grow leaves and begin photmorphogenesis.

what is the purpose of each stage of germination? Once the seed is metabolically activated, germination proceeds according to the following stages: The seed coat (testa) ruptures and the embryonic root (radicle) grows into the ground to extract key nutrients and minerals. The cotyledon emerges and produces the growing shoot's first leaves.

Hereof, what are the three stages of seed development?

Plant seed development comprises a series of morphological, physiological, and biochemical changes and can be divided into three major phases: embryogenesis, including cell division and expansion, seed maturation, and desiccation.

What does the germination stage end?

The germination stage ends when a shoot emerges from the soil. But the plant is not done growing. It's just started. Plants need water, warmth, nutrients from the soil, and light to continue to grow.
