Radicle: Lower embryo and root.

• Do plants have a brain?
• Plants do not have a brain, but they do have
the ability to respond to their environment.
• What direction does the radicle go when it
emerges from the seed coat?
• What direction does the radicle go when it
emerges from the seed coat?
– Does a plant know up from down? Can a
plant sense gravity?
• What would happen to plants if their radicle /
roots grew upward, and their shoots grew
downward?

is a good
thing.” “The
world would be
messed up
without it.”

• Place the arrow to the correct part of this
plant so that it points to the epicotyl.
Copyright © 2010 Ryan P. Murphy
• The epicotyl is the stem above the
cotyledons but below the true leaves
Copyright © 2010 Ryan P. Murphy
• Is the question mark the epicotyl or
hypocotyl? Why?
Copyright © 2010 Ryan P. Murphy
• It is the hypocotyl because it is below the
cotyledons.
