Plant Seeds Quiz: Class 9 Biology

1. The tough, protective outer layer of a dicot seed coat is specifically known as the:

A) Tegmen B) Testa C) Hilum D) Micropyle

2. Which part of the seed embryo is responsible for developing into the primary root of the new plant?

A) Plumule B) Epicotyl C) Radicle D) Hypocotyl

3. What is the primary function of the endosperm in a monocot seed like maize?

A) Protection of the embryo B) Photosynthesis for the seedling C) Food storage for the developing embryo D) Anchoring the seed to the soil

4. The phenomenon where a seed fails to germinate even when provided with optimal external conditions (water, oxygen, temperature) due to internal physiological barriers is called:

A) Quiescence B) Viability C) Dormancy D) Imbibition

5. In epigeal germination, what is the fate of the cotyledons after they emerge above the soil and turn green?

A) They remain underground and provide food. B) They become woody and form part of the stem. C) They become photosynthetic and eventually shrivel and fall off. D) They develop into true leaves immediately.

6. Which of the following plants typically exhibits hypogeal germination?

A) Bean B) Castor C) Pea D) Cotton

A) Scarification B) Vernalization C) Stratification D) Leaching

8. The initial energy required for the metabolic activities and growth of the embryo during germination is derived from the:

A) Absorption of sunlight B) Oxidation of stored food reserves C) Direct absorption of nutrients from soil D) Transpiration from the radicle

9. Seeds with winged structures, such as those of maple and pine trees, are primarily dispersed by which agent?

A) Water B) Animals C) Wind D) Explosive mechanism

10. What is the term for the phenomenon where seeds germinate while still attached to the parent plant, commonly observed in mangrove species?

A) Ovipary B) Vivipary C) Parthenocarpy D) Apomixis
