F Block Vocabulary List

Vocabulary flashcards covering key terms, biological hierarchy, and properties of life from the lecture notes.

Order

The arrangement and structure of unicellular and multicellular organisms, varying from millions of cells with different specializations to fewer cells with simpler structures and functions.

Reproduction

The biological process by which living things create new individual organisms of their own kind.

Natural selection

Individuals in a species more adapt to the environment survive while others die out and the old species evolves into a new one.

Macromolecules

Large molecules that are typically formed by combining smaller units called monomers.

Homeostasis

Having a stable internal environment to sustain life.

Virology

The study of viruses.

Energy Processing

An organism captures energy and converts into nutrients.

Evolution

The process of gradual change during which new species arise from older species.

RAREHOGG

An acronym for the 8 different properties of life: Response to Stimuli, Adaptation, Reproduction, Evolution, Homeostasis, Organized Cells, Growth and Development, Genetics and presence of DNA or RNA.

Molecule

Chemical structure of 2+ atoms bonded together chemically.

Organelles

Cells containing aggregates of macromolecules surrounded by membrane.

Tissue

Groups of similar cells carrying out the same function.

Organs

Collection of tissues based on a common function.

Organ system

Functionally related organs (e.g.: circulatory system, respiratory system).

Organism

Individual living entity.

Population

The amount of a certain species in a specific area.

Ecosystem

All living organisms in a specific area.

Biosphere

The global ecological system where all life on Earth exists.

Community

Sets of populations inhabiting an area.

DNA

An example of a macromolecule, instructions for an organism's cells.

Diversity

A mix of different plants and animals in an ecosystem.

Adaptation

Evolved trait allowing for better survival and "fit" to an environment.

Atom

Smallest and most fundamental unit of matter.

Sensitivity/Response to Stimuli

An organelles response to it's environment.

Cell

The basic structural, functional, and biological unit of all known living organisms.

Prokaryote

A cell lacking membrane-bound nuclei and organelles (ex: Bacteria).

Phototaxis

Cell movement toward/away from light.

Chemotaxis

Cell movement toward/away from chemicals.

Domain

Phylogenetic tree

A diagram showing evolutionary relationships among biologically similar species.

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

Words used to organize species in a hierarchy.

Produces its own food for energy.

Heterotroph

Consumes other organisms for energy.

Thermoregulation

A process where organisms regulate their body temperatures.

Molecular Biology

Biology at the molecular level.
