TVO ILC Part 1: Eight short answer questions 1. Match the following eight angiosperm structures to their functions. List of Structures Calyx, Sepal, Carpel, Ovule, Seed, Stamen, Anther, and Corolla List of Functions A. This structure produces pollen. B. This structure contains the fertilized zygote. C. This structure attracts pollinators. D. This structure is a collection of sepals. E. This structure is the male sex organ. F. This structure is where meiosis takes place in order to produce eggs. G. This structure contains the stigma, style, and ovary. H. This structure protects the developing flower. SBI3U Assessment Grading of Your Learning 2.

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 carried 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 all required nutrients 47 mm; deep green Solution 1 Solution 2 Solution 3 SBI3U Assessment Grading of Your Learning all required nutrients except nitrogen distilled water Copyright © 2021 The Ontario Educational Communications Authority. All rights reserved. 17 mm; pale green-yellow 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); TVO ILC b) 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.

Explain your reasoning. TVO ILC 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 occurring in vegetation type and species diversity over the 45 years. b) What does the pattern of change tell you about what is happening this area? c) Explain how the data supports your conclusion.
