Monocot and Dicot (Eudicot) Seed Minilab
Ref. P. 595-6
Materials:
iodine dropper bottles
scalpel
watchglass
magnifying lens
bean seed (soaked for 24 hours)
corn seed (soaked for 24 hours)
Instructions:
1)
Take one of each seed and place in the watch glass.
2)
Using the magnifying lens, look for structures closely on the outside of the seed. The micropyle is the hole
that allows the entry of water. The hilum is the point of attachment.
3)
Using the scalpel carefully bisect each seed.
4)
Examine the internal structures of each seed. Look for
Dicot/Eudicot Seed:
Bean: cotyledons, hypocotyl, epicotyl, plumules, testa (seed coat)
Monocot Seed:
Corn: cotyledon, epicotyl (hard to see), endosperm, testa (seed coat)
5)
Place 1-3 drops of iodine on each seed. Iodine turns dark blue or black in the presence of starch. Which
seed contains more starch? What is the advantage of storing starch?
Planting Bean and Corn Seeds—Hydroponics
Your teacher will demonstrate this for you:
1)
Take a 400 mL beaker and line it with rolled up paper towels so they cover the edge of the glass. Stuff some
paper toweling in the center of the beaker so the towels firmly touch the edge of the glass of the beaker. Saturate the
paper towels with water and place 1 cm of water at the bottom of the beaker.
2)
Place 2 bean seeds and two corn seeds mid-way up the beaker. Spread them out around the edge and put
them in different orientations (upside down and upright).
3)
Label your name with pencil on the white window. Place the beaker in the window of the classroom.
