2. The small scar on a seed, often visible on beans, indicating where it was attached to the fruit wall, is called the:

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

3. Which of these is generally NOT a crucial external factor required for most seeds to begin germination?

A) Water B) Oxygen C) Light D) Appropriate temperature

4. In which type of germination do the cotyledons remain below the soil surface, like in maize and pea?

A) Epigeal germination B) Hypogeal germination C) Vivipary D) Dormancy
