Question

Which of the following is a step which is involved in seed germination?

• A. Absorption of Water
• B. Absorption of Carbon Dioxide
• C. Absorption of Light
• D. All the above

Answer 1

Answer: (A)

Absorption of Water

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. The water activates special proteins, called enzymes, that begin the process of seed growth.
2. The seed grows a root to access water underground.
3. The shoot appears above ground.

The seed sends a shoot towards the surface, where it will grow leaves to make food that provides energy.
The leaves continue to grow towards the light source in a process called photomorphogenesis.
So the correct option is 'Absorption of Water'
