Which one of the following statements about a plant is true?
(1) The roots will provide food and water for the plant.
(2) The plant will only make food at the adult stage.
(3) The young plant will bear fruit before it bears flowers.
(4) The seed leaves provide food for the developing seed.
我选1,因为root的功能之一是储藏食物。在没有阳光时root就会provide food to the plant.
The four major functions of roots are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) vegetative reproduction.
