4. For a plant colonizing a remote island, describe one advantage and one disadvantage for each of
the following methods: self-pollination and cross-pollination.
5. Three factors that affect plant growth are soil health, nitrogen fixation, and sunlight. Explain how
each factor works to affect the growth of plants.
6. The following experiment was ca
ied out at ILC laboratories to measure the effects of
different nutrient solutions on bean root growth. Three nutrient solutions were made:
Nutrient solutions containing: Results: root length, leaf colour
Solution 1 all required nutrients 47 mm; deep green
Solution 2 all required nutrients except nitrogen 17 mm; pale green-yellow
Solution 3 distilled water 14 mm; pale green-yellow
Interpret the results for each solution. In your answer for each,
a) explain how the solution ranked in relation to the other two (in terms of growth and health of the
plant);

) state the evidence that supports your answer; and
c) explain why the plant grew the way it did.
7. A botanist wanted to see if a new strain of corn could germinate in soil that was too salty for regular
corn. She conducted a study on the germination success of seeds from the new strain that were
exposed to various levels of salty soil, from zero to normal (100 mg/L), high (200 mg/L), very high
(400 mg/L), to normally lethal (800 mg/L).
The table below shows her data for this study.

8. The table shown below represents the number of species growing in an area that was logged using
clear-cutting 45 years ago in Temagami, Ontario. Data was collected periodically over 45 years.
a) Describe the changes occu
ing in vegetation type and species diversity over the
45 years.
) What does the pattern of change tell you about what is happening in this area?
c) Explain how the data supports your conclusion.

Part 2: Three Sisters
You completed this task at the end of the previous learning activity. The instructions have been repeated here
as well. Attach your research table to your solutions from Part 1.
Instructions:
• Read this article titled “Three Sisters Key to Ouendat Survival” from the Midland Mi
or. It
explains the importance of a strategy called companion planting to Indigenous communities.
The Three Sisters play a role in many Indigenous cultures across North America. This article is
about the Ouendat people who come from the North Simcoe region.
• This next article Three sisters harvest deeply spiritual to Ouendat explains more of the history
and legend of the Three Sisters.
• The video “Food Security & Three Sisters Sustainability” is an explanation by Rick Hill,
Tuscarora from the Beaver Clan about what the Three Sisters meant to the Haudenosaunee. It
includes the Three Sisters in the creation and the importance of planting for sustenance of the
community. (Watch from 0:00 – 3:17)
• Rick Hill also provides another story about the Three Sisters and the Three Sisters wampum.
(Watch from 20:20-21:46)
Research
Using the table provided below to organize your research, investigate The Three Sisters and
companion planting. Use the Internet and/or books to research the topic. You can start by
using the websites listed below. In your research include the following:
- An explanation of companion planting
- A description of what each plant contributes to the other two plants and how it
enefits from the other two
- Other versions of the legend about the Three Sisters
- First Nation Farmers and Seeds
- Companion Planting: Three Sisters Garden Plans
