Question

Which of the following is the correct sequence of events happening during germination of a seed
1. The hypocotyl of the germinating seed elongates and pushes the cotyledon above ground
2. Seed absorbs water by wicking moisture through the seed coat into the seed
3.The exterior of the seed cracks open
4. The radicle emerges from the seed and forms into the root

• A. 1-3-4-2
• B. 1-2-4-3
• C. 2-3-4-1
• D. 2-3-1-4

Answer 1

The correct option is C 2-3-4-1

• Initially, the seed absorbs water by wicking moisture through the seed coat into the seed itself.

• Moisture essentially brings the seed back to life.

• Once enough moisture has been absorbed by the seed, the exterior of the seed cracks open.

• At this point, the radicle emerges from the seed and forms into the root.

• The hypocotyl, or stem of the germinating seed, elongates and pushes the the cotyledon above ground.
• So the correct answer is' 2-3-4-1'
