Question

Identify the correct sequence of stages of germination in pea plant.

• A. Bursting of the seed coat, radicle comes out, coleoptile pushed upward, primary root and leaf foliage developed.
• B. Bursting of the seed coat, radicle comes out, plumule pushed upward, primary root developed.
• C. Bursting of the seed coat, radicle comes out, primary root developed, hypocotyl comes out of the soil.
• D. Bursting of the seed coat, coleoptile pushed upward, radicle comes out, primary root and leaf foliage developed.

Answer 1

Answer: (B)

Bursting of the seed coat, radicle comes out, plumule pushed upward, primary root developed.

Germination is the process of seeds developing into new plants. First, environmental conditions must trigger the seed to grow.

1. When water is plentiful, the seed fills with water in a process called imbibition.
2. The water activates special proteins, called enzymes, that begin the process of seed growth.
3. The seed grows a root to access water underground.
4. The shoot appears above ground.
5. The seed sends a shoot towards the surface, where it will grow leaves to make food that provides energy.
6. The leaves continue to grow towards the light source in a process called photomorphogenesis.

So the correct option is 'Bursting of the seed coat, radicle comes out, plumule pushed upward, primary root developed.'
