  15. In flowering plants, a fruit usually develops from what structure?

    Mature ovary

    A fruit usually develops from the mature ovary after fertilization, with the ovary wall often becoming the fruit’s protective outer layer. In some fruits, such as apples, additional flower parts also contribute to the fleshy portion.

  16. Which stimulus guides most roots to grow downward?

    Gravity

    Gravity guides most roots to grow downward, a response called positive gravitropism. Specialized cells in the root cap help sense the direction of gravity.

    Easy · Also offered: Light, Moisture, Touch · Source: Encyclopaedia Britannica: gravitropism

  17. Which nutrient can legumes gain with help from bacteria in root nodules?

    Nitrogen

    Legumes can gain nitrogen through bacteria living in their root nodules, which convert atmospheric nitrogen into forms the plant can use. In return, the plant supplies the bacteria with energy-rich sugars.

  18. What is the edible seed of a corn plant commonly called?

    Kernel

    A corn kernel is the seed of a maize plant, attached to the cob. The husk is the leafy wrapper, and the silk is the bundle of styles, one thread for every kernel it pollinates.

  28. What must a dormant seed take in before germination can begin?

    Water

    A dormant seed is extremely dry. Taking up water swells it, splits the seed coat and restarts the metabolism that drives germination. Botanists call that first soaking-up stage imbibition.

  29. What is the tiny plant within a seed called?

    Embryo
