Question
Transcribed Image Text:2. In a common eudicot pattern of development for the common bean in the figure, the radicle emerges from
the seed (1), then begins to develop into a primary root that grows down into the soil. As this occurs, the
hypocotyl emerges from the seed and bends into the shape of a hook (2). The bent hypocotyl lengthens
and pulls the cotyledons upward (3). When the hypocotyl reaches the soil surface, exposure to light
causes it to straighten (4). Primary leaves emerge from between the cotyledons and begin
photosynthesis. The cotyledons typically undergo a period of photosynthesis before shriveling (5).
Eventually, the cotyledons fall off the lengthening stem, and the young plant's new leaves produce all of
its food.
