Study Notes
Requirements to Define a Living Thing
- Seven fundamental criteria: Organization, Metabolism, Homeostasis, Growth, Reproduction, Response, and Evolution.
- Definitions may vary, but this list serves as a useful guideline.
Homeostasis
- Refers to the regulation of internal temperature regardless of external environmental changes.
Metabolism
- Comprises two main processes:
- Anabolism: The creation of larger cellular structures from smaller units.
- Catabolism: The breakdown of larger cell structures into smaller components.
- Represents the totality of an organism's chemical reactions.
Types of Reproduction
- Asexual reproduction: Involves a single organism dividing itself to create offspring.
- Sexual reproduction: Requires the fusion of sperm and egg cells, resulting in a complete genetic set for a new organism.
Response to Stimuli
- Reflects an organism's ability to respond to environmental stimuli, known as irritability.
- Examples include withdrawing a hand from heat or a plant bending towards sunlight.
Scientific Method Steps
- Observations lead to questions.
- A testable hypothesis is formed.
- Predictions based on this hypothesis are made.
- Predictions are tested through experimentation.
- Results inform new hypotheses and predictions, creating an iterative process.
Glucose
- Also known as dextrose, a fundamental carbohydrate.
Glucose Structure
- The glucose chain transitions to its cyclic form at the oxygen in the aldehyde functional group.
Saccharides
- Defined as sweet substances, commonly understood as simple sugars and monomers.
Starches
- Recognized as examples of polysaccharides, which are complex carbohydrates made from many sugar units.
