Biology - H Flashcards
Order
Living cells are the basis of this complex
Reproduction
organisms reproduce their own kind
Growth and Development
consistent growth and development controlled by inherited DNA
Energy Processing
acquiring energy and transforming it to a form useful for the organism
Response to the Environment
all organisms respond to environmental stimuli
Regulation
Many types of mechanisms regulate an organism’s internal environment, keeping it within limits that sustain life.
Evolutionary Adaptation
adaptations evolve over many generations, as individuals with traits best suited to their environments have greater reproductive success and pass their traits to offspring
Biosphere
the part of Earth where life exists
Ecosystems
A biological community of interacting organisms and their physical environment.
Community
A group of interdependent organisms inhabiting the same region and interacting with each other
Population
group of individuals of the same species that live in the same area
Organisms
Individual living things
Organ System
group of organs that work together to perform a specific function
Organ
group of tissues that work together to perform closely related functions
Cell
Basic unit of life
Organelle
A tiny cell structure that carries out a specific function within the cell
Molecule
A group of atoms bonded together
Atom
Basic unit of matter
Emergent Properties
result from the arrangement and interaction of parts within a system
System Biology
constructs models for the dynamic behavior of whole biological systems
Kingdom Plantae
Consists of multicellular plants.
Kingdom Fungi
Consists of unicellular and multicellular organisms that cannot make their own food (heterotrophs)
Kingdom Animalia
a kingdom a of multicellular, eukaryotic organisms that are free-moving, and lack cell walls; classified under Domain Eukarya
Charles Darwin
English natural scientist who formulated a theory of evolution by natural selection (1809-1882)
Eukaryotic cells
Contain a nucleus and other organelles that are bound by membranes.
Prokaryotic Cell
cell that does not have a nucleus or other membrane-bound organelles.
Archaea
One of two prokaryotic domains, the other being Bacteria.
Fungi
An organism that absorbs nutrients from the environment.
Protists
eukaryotes that cannot be classified as animals, plants, or fungi
Properties of Life
order, regulation, growth and development, energy processing, response to the environment, reproduction, evolution
Unity
The state of being united or forming a whole.
Diversity
the state of being diverse; variety.
Levels of Organization
biosphere, ecosystem, community, population, organism, organ system, organ, tissue, cell, organelle, molecule, atom.
Homeostasis
process by which organisms maintain a relatively stable internal environment
