(STSE) g. Investigate horticulture through activities such as designing or planting a garden plot. (S) h. Critique the economic, environmental, and social impacts of small-scale and large-scale agricultural practices. (STSE) i. Analyse current forestry practices and technologies (e.g., selective cutting, clear cutting, and integrated resource management) in terms of productivity, profitability and environmental stewardship. (STSE) Role of Plants a. Discuss the many roles of plants including their roles as providers of ecological goods and services as well as natural capital. (K) Brainstorm – list 10 ways plants are used or are important to our world (likely an long answer question tied to this). fossil fuels – pressurized organisms from millions of years ago. Food (for organisms/heterotrophs) Homes/habitats for organisms Plants convert CO2 into O2 Lumber – building purposes. Aloe Vera (sunburn relief) – medicinal purposes Pain relief, recreational use Dyes and colours Direction of scientific study – understanding plants Religious beliefs/significance/practices. Beautification/decoration (Holidays – wreathes, trees, pumpkins) Flood control Natural capital – what does it involve? Role of Plants a. Discuss the many roles of plants including their roles as providers of ecological goods and services as well as natural capital. (K) Brainstorm – list 10 ways plants are used or are important to our world (likely an long answer question tied to this). Adding oxygen to the atmosphere Food! Veggies! Important sources of food for animals food for “me”. More plants = greater biodiversity Trees provide shade! Soil moist, people cool! Lumber – building houses Medicine! Most drugs are rooted in plants! Plants have a recreational use! Growing, Climbing Composting – breaking down to refresh soil HOMES FOR ANIMALS! Beautification Natural capital – what does it involve? Plants are used for… Shade Photosynthesis Oxygen Tobacco/marijuana Relaxant, pain reliever Adding flavours – eating - cooking Smelling – improves life. Decoration - beautification Protects soil from light and holds moisture Biofuel – ethanol – wheat. Burning wood! Use wood to make a house! Fossil fuels – condensed organic matter over time! https://www.youtube.com/watch?v=ysa5OBhXz-Q How wolves change rivers ^ Role of Plants – Climate Change’s Impact f. Analyze the relationship between plants and climate change, including plants’ roles in reducing greenhouse gases, as well as potential impacts of climate change on plant growth and distribution. (STSE) Quick Open Discussion Based on what we know about climate change, how would it potentially affect plant growth? How would/could plant growth mitigate climate change? Create and Answer 5 Q’s Pg 1 to Pg 2 Including Climate Changes Impact Plant Growth and Distribution Role of Plants – First Nations and Metis Culture b. Examine the role of plants in First Nations and Metis cultures (medicinal, spiritual, nutritional, and shelter). (K, STSE) Three Sisters Planting Nutritional and Spiritual Significance PP – Phones & Partners Medicinal – search for three with a partner and include: - Name (common and scientific) - Significance/Use – http://www.nativeorchid.org/dorisMedicinalPlantTradi tionalUses.htm Shelter “They built the frame of the house with young saplings set in a circle and tied together at the top, and covered the frame with mats woven from cattails as well as birch bark.” http://www.ecokids.ca/pub/eco_info/topics/first_nations _inuit/shelter.cfm Tipis – used from tall, straight trees and buffalo hide. VIDEO! I got a comment last year, why do we always have to learn about First nations stuff, felt this before? Video on a guy describing 3 Sisters Planting… I think he’s cute. And not FN! https://www.youtube.com/watch?v=t9crvQj-eS4 CORN n BEANS. CORN n BEANS. CORN n BEANS SQUASH SQUASH SQUASH SQUASH SQUASH Self Check Assignment 1. List 10 ways plants are used or are important to our world (.5 marks each) 2. Define the term natural capital and state how this term may apply to plants as providers of ecological goods and services (use an example from your list above). (2 marks) 3. ANSWER TWO OF THE FOLLOWING (6): a. What are the three plants associated with Three Sister’s Planting (3), b. how do they interact and benefit one another (3), c. what does each plant provide nutritionally (3) Bonus What is a spiritual lesson or interpretation we can take from the symbiotic (working together) relationship between the plants involved in Three Sisters Planting? Plant Morphology and Physiology c. Explain how plant morphology and physiology determines the role of plants in an ecosystem (e.g., leaves and photosynthesis, stems support and conduct fluids, roots anchor, absorb and store starch).(K) Plant Physiology 101 Plants = multicellular, eukaryotic, sexually (and asexually) reproduce. Some have seeds, some don’t. Lots of ways to classify. Discussion – list plants and compare their impact. Nonvascular and vascular plants. Vascular have true roots, stems, and leaves. Leaves – Function: create sugars/food for plant through Photosynthesis (and uses some of that in Respiration) Plant Morphology and Physiology c. Explain how plant morphology and physiology determines the role of plants in an ecosystem (e.g., leaves and photosynthesis, stems support and conduct fluids, roots anchor, absorb and store starch).(K) Stems – woody, herbaceous, vine, and shrubs. Functions: Provide stable support for plants, is a means to transport nutrients. Nodes and Internodes. Roots – Functions: store excess carbohydrates as starch; are responsible for water and mineral uptake. Anchor plant in place. Net Primary Productivity d. Interpret the relationship between photosynthesis, respiration, and net primary productivity. (K) Gross Plant Carbon (organic material production - photosynthesis) – Plant Respiration (doing work – cellular respiration) = Net Primary Productivity (what is actually available to the plant and consumers) Self-Check Assignment Answer the following /20 List the three different structures of vascular plants and what their functions for the plant are (6). What is the difference between a vascular plant and a nonvascular plant (2)? What is net primary productivity? How is it calculated? What ecosystems is it greatest in? What ecosystems is it the least in, why? (5) Justify – what is your favourite plant and why? Is it vascular or nonvascular (3)? What are the two vascular tissues (like veins) in vascular plants and what do they transport? (4) Applying Plant Morphology to Pesticides/Agriculture Crops have vascular tissue – xylem (one direction water and mineral transport from roots up) and phloem (any direction nutrient transfer throughout plant where needed). Some pesticides damage roots, which will affect water uptake, which will inhibit photosynthesis. CO2 + H2O + energy C6H12O6 + O2 Plant Pollination and Reproduction Factors e. Assess factors (e.g., monocultures, climate change, pesticides, and disease) which influence plant pollination and reproduction. (K) Monocultures and Disease (polycultures help, use different strains of the crop). Climate change – temperature changes, how could invasive species come as a result? Pesticides – root issues. Soil – Outcome: Analyze soil as an integral component of terrestrial ecosystems. Different types of soil! Which has the biggest particle size? Clay – smallest particle size Silt - middle Sand - largest Mix of them is called loamy soil What is found most around Moose Jaw? Clay! Different soil = different vegetation = different organisms. Biodiversity – Outcome: Recognize the need for intact habitat to support animal populations Biodiversity: variety of life. More variety = more biodiversity. Why is biodiversity important? More biodiversity keeps an ecosystem more stable, if something bad happens to one species it may not affect every other species. Part of biodiversity Species diversity – how many different species live somewhere. Genetic diversity – number of genetic characteristics in the makeup of species. Ecosystem diversity – variety of ecosystems in an area Why important? We need to protect all of these! What damages it? Habitat fragmentation – active separation of a habitat by farmland, roads, or other means. Habitat loss – removal of habitat completely (can be for roads or farmland) How do we protect it? Create and support environmental policies! (Unit 1)
