Key concept: Systems
Related concepts: Environment and form
Global context: Globalization and sustainability.
Inquiry questions:
Factual:
What are the features of a vascular plant, which explain the process of photosynthesis?
What are the biotic and abiotic factors that influence plant growth?
How do flowering plants reproduce?
Conceptual:
How do plant forms support plant functions?
Debatable:
How can the environment be made sustainable if plants are increasingly being grown by artificial (synthetic) means?
Summative tasks:
Criterion A test:
Explain knowledge of plant systems and function, apply that knowledge to solve problems in familiar and unfamiliar situations.
Criterion B and C Investigation:
Design, conduct and evaluate an independent investigation into different factors affecting the germination or growth of plants based on a particular geographic location in the world where environmental factors differ.
Learning targets for this unit are as follows:
1) Describe the role of plants as primary producers in the environment.
2) State the equation of photosynthesis.
3) Describe the role of plants in exchanging CO2 and O2 from the atmosphere.
4) Annotate and describe the functions of key plant structures (roots, stem, leaves, flower, vascular tissue (xylem, phloem), sinks or storages for carbohydrates).
5) State and explain - Abiotic needs of plants: water, CO2, temperature/ light, humidity, minerals for growth (soil)
6) State and explain - Biotic needs of plants: soil (decayed organic matter- humous), competition for space and light, animals for seed dispersal
7) Annotate and describe the male and female parts of a flower (carpal: stigma, style, ovary, ova; stamen: anther, filament, pollen)
8) describe pollination and fertilization
9) Describe different features of seeds and seed dispersal methods
10) Describe the role of bees or insects in pollen dispersal
