Study Notes
Plants: Anatomy, Growth, and Function
- Plants play crucial roles in nature and society, providing food, medicines, building materials, and energy.
- Human food supply primarily comes from a small number of plant species.
- Canola, a variety of rapeseed, is a key Canadian export, used for oil and biodiesel.
- Plants are used in numerous industrial applications, including inks, paints, plastics, and dyes.
- Plants provide essential ecosystem services, benefiting human populations and sustaining environmental balance.
- Sustainable forestry and agriculture prioritize maintaining biodiversity and resource availability for future generations.
- Canada's Aboriginal peoples have a long history of utilizing plants for medicinal purposes.
- Plant-based medicines are crucial in modern healthcare, and many prescription and non-prescription drugs are derived from plants.
- The demand for sustainable plant-based products is increasing due to concerns about fossil fuels and greenhouse gas emissions.
Plants and People
- Early humans relied on wild plants as a primary food source, later developing agriculture to produce food more reliably.
- Today, a small number (approximately 14) of plant species form the basis of most human food.
- Wheat, canola, barley, corn, soybeans, potatoes are significant Canadian crops.
- Cereal grains are a crucial food source for both humans and domesticated animals.
- Edible plants vary significantly from flowering plants (angiosperms) to broad-leaf plants.
Plants as a Source of Pharmaceuticals
- Plants have been widely used traditionally in medicine.
- Many modern medicines are derived from plant compounds.
- Examples include Aspirin (acetylsalicylic acid), extracted from willow bark; chemicals used in cancer treatments; laxatives, and stimulants from plants.
- Plant-based drugs represent approximately 25% of all drugs prescribed.
Plants as a Source of Fuel
- Plants are a primary source of fuel for various activities.
- In the past, wood and peat were the primary energy sources.
- Now, fossil fuels (coal, oil, and gas) are dominant.
- Biofuels, produced from plants, are emerging as a renewable alternative to fossil fuels.
- Ethanol, derived mostly from corn, and biodiesel, based on plant oils like canola, are used.
- Biofuel production may necessitate land usage for crops, potentially impacting food production and prices.
Plants as Building Materials
- Wood, from both temperate and tropical hardwoods, is crucial for construction and furniture.
- Softwoods (like pine and spruce) provide materials for paper and building products.
- Plant-based materials like inks, paints and plastics are becoming increasingly economical and popular.
Plants and Disturbance and Recovery
- Natural or human-caused disturbances affect plant communities.
- Ecological succession refers to the changes in plant communities over time following a disturbance.
- Primary succession, occurring in areas with no existing soil, involves pioneer species.
- Secondary succession, following a disturbance that leaves soil intact, is faster than primary succession.
- Disturbances can contribute to biodiversity by creating different habitats.
- Disturbances are an important component of the natural community cycle.
Plants and Sustainable Practices
- Integrating aspects of sustainability in agriculture and forestry is critical to continuing these endeavors.
- Sustainable agriculture emphasizes maintaining biodiversity, utilizing soil and water resources efficiently, and preventing erosion.
Climax Communities
- A climax community refers to a mature plant community in a region that is in equilibrium with its environment.
- Succession patterns are often modified by disturbance in a region.
- Modern ecological understanding recognizes that climax communities are not always stable and are influenced by multiple factors.
- Succession is a dynamic process, and communities constantly respond to environmental challenges.
