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!

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 –

 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.”

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!

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)
