  1. Get in Touch with Trees! CLIMATE CHANGE AND MICHIGAN FORESTS Lesson 1

  2. Why Are Forests Important? • Prevent soil erosion • Water retention • Cooling • Carbon sink • Jobs & Careers • Other ______________ • Habitat • Economy • Recreation • Nutrient cycling • Air purification • Other______________

  3. How do plants grow?

  4. What factors affect plant growth?

  5. Temperature: How does temperature affect plant growth?

  6. Temperature determines how fast photosynthesis occurs. • Temperature influences how much wateris available for plants to use for photosynthesis.

  7. Precipitation: How does precipitation help plants grow and survive?

  8. Precipitation • Photosynthesis – Precipitation influences how much water plants can access and use for photosynthesis and growth. • Heat movement – Plants allow water vapor to exit openings in the leaves, taking heat with it. • Structure – Water held in plant cells gives plant leaves and stems shape and structure.

  9. Light: How does light affect plant growth?

  10. The amountof light and the intensity of light plants receive determine how much energy is available for photosynthesis.

  11. Soil: How does soil type affect plant growth?

  12. Soil type determines how much water and what types of minerals are available.

  13. Precipitation Temperature Are these factors the same in every environment? Soil Light

  14. Trees grow where they are adapted to live

  15. Conifers are adapted to colder climates • Smaller, waxy needles limit water loss and protect photosynthetic cells. • Keeping leaves year-round saves energy and allows photosynthesis to occur when conditions permit. • The cone shape of the tree helps conifers drop heavy snow.

  16. Deciduous trees are adapted to more moderate climates • Broad, flat leaves capture more light. • The open shape of the branches exposes leaves to the maximum amount of light possible. • Shedding leaves prevents water loss and damage during winter.

  17. Wrap Up • Forests provide important services for humans and the environment. • Factors that affect plant growth include: temperature, precipitation, light, and soil type. • Plants are adapted to grow in a particular environment.
