Study Notes
Classification and Naming
- Latin is the foundational language for naming taxa in biology.
- Scientific names are written in italics for clarity and standardization.
- The binomial nomenclature system assigns two names to organisms: one for genus and one for species.
Biological Processes and Structures
- Differentiation allows cells to develop specialized functions and forms.
- Eukaryotic cells contain a nucleus and membrane-bound organelles, distinguishing them from prokaryotic cells.
- Heterotrophic organisms rely on consuming other organisms for energy, unlike autotrophs that produce their own food.
- Ingesting food is essential for animals before digestion occurs.
Classification Categories
- Taxonomy is the science dedicated to naming and grouping species based on characteristics.
- Hierarchy refers to the ranking system used in classification, from domain down to species.
- A dichotomous key is a helpful tool that allows individuals to identify species through a series of choices.
- Domain is the broadest category in taxonomic classification.
Animal Groupings
- Invertebrates encompass 94% of all animal species, showcasing vast diversity.
- The oldest known type of animal in evolutionary history is the sponge.
- Cryptic species look alike but can be genetically distinct, identified through DNA testing.
- Larvae represent immature stages of certain animals undergoing significant transformations to reach adulthood.
Movement and Behavior
- Motile organisms can freely move in their environment, while sessile organisms are permanently fixed in one location.
- Sedentary organisms can move, but do so infrequently.
Specialty Terms
- Zooxanthellae are essential photosynthesizing algae living within other organisms, often in symbiotic relationships.
- Morphology studies the form and structure of organisms, playing a key role in modern classification.
Historical Figures
- Linnaeus is credited with establishing the modern taxonomy framework.
- Aristotle was the first to attempt systematic classification of organisms.
Energy Storage and Usage
- Unused energy in animals is stored as glycogen in the liver and muscles.
Evolutionary Concepts
- Evolution refers to the gradual process through which species change over time.
- A cladogram visually represents the evolutionary relationships among organisms, illustrating how they are interconnected through common ancestry.
Other Notable Terms
- Specific epithet is the second part of a scientific name, providing further identification.
- The term heterogametes collectively describes the gametes (sperm and egg) that animals produce for reproduction.
- Barnacles are specific examples of sessile arthropods, often found attached to maritime surfaces like boats and whales.
