BIOTECHNOLOGY
DNA Extraction from Fast
PlantsStudents can
grow and extract DNA from Fast Plants using dishwashing soap and meat
tenderizer. This is an activity with an easy to moderate level of
difficulty, appropriate for high school and college students. The activity
can also be used to explore the concepts of biotechnology. Special
materials: blender, 7-day-old Fast Plants. Source: Medfield
High School.

Chromosome Squashes
Using Fast Plants
Stages of mitosis can be identified in the cells of immature Fast
Plants flower buds and the meristematic regions of root tips. The slides
can be prepared following the protocol used for onion root tip
preparations. This is a difficult activity appropriate for advanced high
school and college students. Source: Carolina Biological Supply

Inducing Polyploidy in
Fast Plant Cells
Students can examine the effect of colchicine on meristematic cells by
applying a solution to the apical meristem at the onset of flower bud
formation. Using the procedure for chromosome squashes in root tips,
students will be able to see and count the affected chromosomes. This is a
difficult experiment suitable for advanced high school and college
students. Source: Medfield High School.
Finding Restriction Sites
in Fast Plant DNA
Students can extract DNA from Fast Plant tissue and use common restriction
enzymes to determine if the DNA contains sites specific to these enzymes.
This is a difficult experiment appropriate for advanced high school and
college students. Special materials: electrophoresis equipment,
restriction enzymes. Source: Medfield High School.
Culturing Fast Plants by
Hydroponics
Fast Plants can be grown successfully without soil in a hydroponic
growing solution. A mineral solution is used as the aqueous base for the
plants. A gentle hand is required for working with the young plants. This
is a difficult experiment appropriate for high school and college
students. Source: Carolina Biological Supply Company.
Demonstrating Capillary
Action with Fast Plants
Capillary action in plants can be shown by cutting a 14-day-old Fast Plant
off at about 2 centimeters above the soil line and putting the stem into
brightly colored water for 24 hours. Does the plant show signs of having
drawn up the color from the water? This is an easy experiment appropriate
for middle and high school students. Special materials: food
coloring, 14-day-old Fast Plants. Source: Wisconsin Fast Plants.
