Cotton plant adaptations Structural Activity Objectives Behavioural/ Internal Teacher's Notes Activity Notes Cotton plant adaptations activity objectives Students will: 1 Sort adaptations suited to the Australian environment 2 Explore adaptations that aid the survival of the cotton plant in harsh environments Activity Objectives Teacher's Notes Activity Notes Sorting 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 Behavioural/ Internal Sorting check Directions Are your answers the same or different?

Sorting 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? 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. Structural Behavioural/ Internal Sorting check Directions Drag each item to the correct section of the Venn Diagram.

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 Cotton plant adaptations activity teacher notes Sorting 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 http://cottonaustralia.com.au/uploads/resources/CottonAdaptationsLesson.pdf ©Cotton Australia 2017.
