Seed Germination Quiz

What is the first step in the germination process?

• Seed dispersal

• Water absorption

• Pollination

• Photosynthesis

Which environmental factor is crucial for initiating germination?

• Cold temperatures

• Complete darkness

• Adequate moisture

• High humidity

What occurs during the process of imbibition in germination?

• Formation of the seed coat

• Absorption of water by the seed

• Emergence of the radicle

• Development of the shoot

Which part of the seed typically emerges first during germination?

• Cotyledon

• Hypocotyl

• Epicotyl

• Radicle

Why is oxygen important for the germination process?

• It provides energy for the seedling

• It facilitates the breakdown of stored nutrients

• It promotes water absorption

• It induces dormancy

What is the term for the initial growth of the embryonic root during germination?

• Hypocotyl elongation

• Radicle emergence

• Plumule development

• Cotyledon expansion

Under which condition does light play a crucial role in germination?

• Germination of sun-loving plants

• Germination of shade-tolerant plants

• Germination of all plant species

• Germination in complete darkness

At what point is a seed considered to have completed germination?

• When the shoot emerges above the soil

• When the first true leaves appear

• When the cotyledons wither and fall off

• When the roots reach a specific length

What role do enzymes play in the germination process?

• They inhibit water absorption

• They break down stored nutrients into usable forms

• They form the protective seed coat

• They regulate light exposure

What is the primary purpose of the cotyledons during germination?

• Energy storage

• Photosynthesis

• Water absorption

• Protection of the embryonic shoot
