1. Plant Adaptation

2. Adaptation What environmental conditions must plants, animals and humans adapt to? means adjusting to specific environmental conditions or factors

3. Environmental conditions in Canada Short summer; long extremely cold winter Short, cool summer; cold winter Hot summer; cold winter

4. Comparing leaf shape in three plants from three different environments Mini Activity

5. A B C Cards A BC Environmental condition

6. A B C Create a collage Name the environmental condition plant experiences. Why? How do the adaptations of this plant help it survive in this environment?

7. A B C Create a collage

8. A B C Cards Hot, dry desert conditions Wet, humid conditions, tropical rainforest Nutrient poor soil Reduced leaf size helps plant to avoid water loss Leaf consume insects for extra nutrients Leave shape lets rain runoff them easily, preventing fungi to grow on leaf surface

9. Plant adaptations in different environments throughout Canada

10. 1.Tundra DescriptionPlant adaptationExample: Image Short summer; long, extreme cold winter Plants grow close to the ground due to lack of nutrients in soil Some plants are covered with hair to avoid freezing 2. Temperate Rainforest DescriptionPlant adaptationExample: Image

11. Is it better to run or walk in the rain?

13. Ripening Bananas Some people say putting bananas in a brown paper bag and sealing it will ripen the banana more quickly. Does it work? Find out by experimenting at home

14. Plant Hormones Regulate Growth and Development What are some of the advantages of humans understanding the functions of plant hormones?

15. 1. What is a hormone? A hormone is any chemical produced in one part of the body that has a target elsewhere in the body. Plants have five classes of hormoneshormone

16. Name of HormoneWhat does it do? Where is it produced? 1.Auxin Buds or stem tips and roots 2.Gibberellins Anthers 3.Cytokinins Roots, shoots 4.Abscisic Acid Leaves, chloroplasts 5.Ethylene Germinating seedlings Stimulate plant growth Break dormancy cycle in seeds and buds Stimulate plant growth and development Promote cell division Delay ageing of fruit and leaves Inhibits plant growth Sends seeds and buds into dormancy Promotes ripening of fruit

17. Name of HormoneHow it is used in agriculture, forestry and urban forestry Auxin  Applied to cuttings to stimulate growth.  By cutting off the terminal bud, gardeners can promote the growth of side branches Gibberellins  Used by farmers to increase fruit size  Used in brewery to stimulate germination in barley seeds Cytokinins  Used to grow clones of plants  Used by florist to lengthen time cut flowers stay fresh Abscisic Acid  Applied to greenhouse crops before transition to field to reduce shock from change in environmental condition Ethylene  Used to ripen large quantities of commercial fruits after they arrive at sale destination

18. Ripening Bananas Some people say putting bananas in a brown paper bag and sealing it will ripen the banana more quickly. Does it work? Find out by experimenting at home

19. Bananas ripening occurs naturally A chemical substance produced by plants causes ripening. What is this chemical substance generally called? Knowing about hormones has helped in ripening bananas for___________________________purposes How many classes of plant hormones did we talk about? Name some

24. TROPISM is a biological phenomenon, indicating growth or turning movement a plant does in response to an environmental stimulus

25. TROPISM POSITIVE If the plant moves TOWARD the stimulus NEGATIVE If the plant moves AWAY from the stimulus

26. Gravitropism http://www.youtube.com/watch?v=mYZXax8V_L0&feature=related&safety_mode=tru e&persist_safety_mode=1 Movement of plants in response to gravity Positive is toward gravity (roots grow down) Negative is away from gravity (shoot, stems, and leaves grow up) Why? Allows plants to grow properly and get nutrients and sunlight

27. Phototropism Movement of plants toward light Why? Maximize amount of sun for photosynthesis to make their food.

28. Thigmotropism http://www.youtube.com/watch?v =8HeedWWe6VA&feature=relate d&safety_mode=true&persist_saf ety_mode=1 Plants moving in response to touch. Positive is toward touch (vines wrap around structures) Negative is away from touch (some plants close up when touched) Why? to support leaves as they grow higher to reach the sun to make more food (photosynthesis).
