• What do the tree branches have that the
roots do not?
• Can a plant get a drink of water like this?

• Do plants have fat / large stomachs for
storing food and energy?

Draws minerals and water from the
surrounding soil.

• Answer! Potatoes are part of a tuberous
root system.
“I didn’t know
that.”
Copyright © 2010 Ryan P. Murphy
• Planting potatoes during the medieval times
was a good idea because they are tough to
dig up.
– Your fields could be burned and easily
destroyed. Your potatoes won’t be harmed.

• Another type of roots can be adventitious
roots which run along the ground anchoring
the plant.

• Activity! Weeding the Property / Root
Observation.
– Please visit a few plants / weeds and remove
them from the ground by holding them close
to their base. (watch for thorns / other
dangers). Wear Gloves if possible.
– Identify which are taproots, and which are
fibrous roots.
Copyright © 2010 Ryan P. Murphy
• Activity! Investigating your plant study.
– What type of roots do your plants have?

• Activity (Optional) Root
Growth,
• Cut leaf close to the stem.
– African Violet works well, many
other species that propagate
from cuttings can be explored.
• Add fertilizer to some water in
a container.
• Cover with foil and make
small hole for the stem.
• Slide leaf stem into hole so it
touches the water.
• Root growth will appear in a
few weeks.

Vascular system: The vessels and tissue
that carry or circulate fluids such as blood
or lymph or sap through the body of a
animal or plant.

• Explanation: Water will travel up the celery
through the xylem. The water molecules
climb up the small tubes because of
adhesion, called capillary action.
