Which of the following statements accurately describes a key difference between the mature seed of a common garden bean eudicot and maize monocot , as illustrated and described in the text?

  • A: Common garden bean seeds have a scutellum for nutrient absorption, while maize seeds have two fleshy cotyledons for food storage.
  • B: Maize seeds possess a single cotyledon called a scutellum, which transfers nutrients from the endosperm, whereas common garden bean seeds typically have two fleshy cotyledons that store food absorbed from the endosperm.
  • C: Both maize and common garden bean seeds store their primary food supply within a large endosperm.
  • D: The coleoptile covers the young root in maize, while the coleorhiza covers the young shoot.

Explanation

According to the text and Figure 38.8b, maize, a monocot, has a single cotyledon called a scutellum that absorbs nutrients from the endosperm. Figure 38.8a and the text explain that common garden beans, a eudicot, have two fleshy cotyledons that store food absorbed from the endosperm.
