Seed Germination and Oxygen Experiment Quiz

What is seed germination in the context of higher plants?

• The production of seeds in flowering plants

• The process of photosynthesis in plants

• The gradual development of a mature plant from a fertilized ovule

• The shedding of leaves in autumn

Which of the following is NOT an extrinsic factor affecting seed germination?

• Water

• Oxygen

• Seed coat thickness

• Temperature

What is the purpose of using two flasks in the seed germination experiment?

• To test the effect of different seed types

• To compare the effects of oxygen presence and absence

• To demonstrate the role of light in germination

• To compare the effects of different temperatures

Why are the seed pouches suspended above the liquid in the flasks?

• To prevent the seeds from getting wet

• To allow air circulation around the seeds

• To ensure they receive enough sunlight

• To keep them at a constant temperature

What conclusion can be drawn from the experiment regarding oxygen's role in seed germination?

• Oxygen is only needed for certain types of seeds

• Oxygen is not necessary for seed germination

• Oxygen is a vital factor for the initiation of seed germination

• Oxygen inhibits the germination process
