Practice questions testing deep understanding of seed anatomy, types of germination, and required conditions.
Q1. A student sows bean seeds in wet soil and places them in a tightly sealed glass jar, removing all the oxygen inside. Even after providing adequate warmth and water, the seeds do not germinate. Explain the biological necessity of oxygen for seed germination.
Q2. Compare the structure of a dicot seed (like a gram or bean) with a monocot seed (like maize) regarding where they store food for the developing embryo.
Q3. Assertion (A): During epigeal germination (like in a bean), the cotyledons are pushed above the ground. Reason (R): The hypocotyl (the region of the stem below the cotyledons) elongates rapidly, forcing the cotyledons up out of the soil.
