Study Notes
Cell Structure and Function
- A cell is the basic unit of a living organism, performing all its life processes.
- Microbiology is the study of microscopic organisms.
Digestive System
- Nutrient absorption occurs in the small intestine.
Reproduction
- Budding is a form of asexual reproduction where a new organism grows from an outgrowth.
Respiratory System
- The trachea, also known as the windpipe, is part of the respiratory system.
Proteins and Prions
- Proteins make up prions, which can cause diseases.
Organisms
- Unicellular organisms lack membrane-bound organelles.
- A nucleus contains an organism's genetic material.
- Yeasts feed on decaying matter.
- A human adult has 206 bones.
- A human infant has 150 bones.
Classification
- Carolus Linnaeus is considered the "Father of Nomenclature".
- Melanins are pigments that determine skin color.
- Arteries carry oxygen-rich blood to the body.
Energy and Photosynthesis
- Light is the energy source for photosynthesis.
- A phylum is a broad taxonomic category that includes other categories.
Reproduction in Plants
- Cross-pollination occurs when pollen is transferred from one flower's stigma to another.
Animal Life Cycles
- Metamorphosis is the life cycle undergone by insects.
Animal Characteristics
- Snakes are cold-blooded animals.
Symbiotic Relationships
- Mutualism is a relationship where both organisms benefit.
- A starfish is not a fish.
Maintaining Internal Balance
- Homeostasis is the process organisms use to maintain a stable internal environment.
Food Chains and Consumers
- Examples of food chains include (plant -> rat -> hawk)
- Secondary consumers (like the chicken in the presented example) eat primary consumers (like the worm in the example).
Environmental Relationships
- Biomes encompass all previously mentioned levels of biological organization.
- Estivation is a period of reduced activity by animals during the summer.
- Habitat is the natural environment where an organism lives.
- Four basic needs of living things are air, water, food, and a suitable habitat.
