Directions
Drag each
item to the
correct section ​of the
Venn ​Diagram.
Go to the next slide to
show ​answers. Are
​your answers ​the
same or ​different?
​W hy?
The seed
contains just
enough
carbohydrat
e to produce
the first root
and first two
leaves
(cotleydons).
The plant sheds
flowers or small
bolls when the crop
has inadequate
moisture, sun,
nutrients,
carbohydrates so
that it can support its
leaves, branches,
roots and remaining
fruit.
Hairy leaves
protect the plant
from insects.
Shiny leaves
help to regulate
water loss
Structural
The leaf and stem
contains gossypol- a
chemical which is
unpleasant to insects

Hairy leaves
create a
microclimate
protecting the
plant from
extremes of heat
and cold.
The leaf of
transgenic cotton
has been bred to
contain the BT
gene. It is poisonous
for the heliothis
caterpillar
The plant sweats
when it is too hot
to keep cool
Structural
Uses energy from
the nearest leaf and
transfers this to the
nearest boll (fruit).

The plant
constantly
grows new
leaves as new
leaves are more
efficient than old
ones
Big leaves
allow the plant to
maximise the
exposure to light.
Nutrients can be
moved
throughout the
plant to support
developing fruit.

Cotton plant adaptations activity notes
Lesson Activity
• Students drag items to the correct section of the chart then go to the
next page to check their answers.
• Independent pages can be used as a small group activity, or
reinforcement for students who need practice understanding
adaptations

These activities are aligned to the Australian National Curriculum specifically Science
/ Year 5/ Science Understanding/ Biological Sciences. It is designed to help meet the
content descriptor ACSSU043 'Living things have structural features and adaptations
that help them to survive in their environment.
They are designed to compliment the 'Cotton plant adaptations lesson' which can be found on
Cotton Australia's Cotton Classroom website at
