UNIT 1 - ALL TERMS Flashcards
Characteristics Of Life
ORDER
organization within an organism based off living cells
ex. each cell has a certain function
Characteristics Of Life
REPRODUCTION
Capability to reproduce
Characteristics Of Life
GROWTH & DEVELOPMENT
Inherited DNA dictates path for the growth and development of organisms.
Characteristics Of Life
ENERGY PROCESSING
(food) chem. energy in food to power its own processes and reactions
Characteristics Of Life
RESPONCE TO ENVIROMENT
response to environmental stimuli
Characteristics Of Life
REGULATION
Internal mechanisms that regulate the body
ex. body temp, urination
Characteristics Of Life
EVOLUTIONARY ADAPTATION
Evolution over mult. generations via natural selection
def. HOMEOSTASIS
steady internal envirometn
Order the Hierarchy of LIFE
(largest -> smallest)

Organelle
Molecule
def. BIOSPHERE
All environments on EARTH that support life
def. ECOSYSTEM
Contains all life living within a particular area with set conditions (air, soil, water, sunlight)
def. COMMUNITY
the array of organisms within the ecosystem
def. POPULATION
all individuals of a SPECIES within a certain area
def. ORGANSIM
an individual living thing
def. Organ System
mult. organs that cooperate for a specific function
def. ORGAN
several diff. tissues combined
def. TISSUES
group of similar cells preforming a specific function
def. CELL
building block of life (contains organelles)
LOWEST LEVEL OF STRUCTURE THAT CAN PREFORM ALL REQUIREMENTS OF LIFE
def. ORGANELLE
membrane enclosed structure performing a specific cell function (ex. nucleolus)
def. Molecule
org. cluster of chemical units held through chemical bonds (DNA)
EMERGENT PROPERTIES
increase complexity of interactions upward in the hierarchy yields new properties
What is the Cell’s purpose in multi-celled organism?
To support REPRODUCTION & GROWTH AND REPAIR
Most bacteria are ____ - cellular organisms
SINGLE
Shared Characteristics b/t Prokaryotic and Eukaryotic cells
- membrane (regulates passage b/t cell and surroundings)
- uses DNA as genetic information
What is the role of PRODUCERS in an ecosystem?
provides food for the typical ecosystem
EX. TREE
absorbs water & co2 — sunlight— photosynthesis—–»_space; sugar and o2
What is the role of CONSUMERS in an ecosystem?
EAT PLANTS AND OTHER ANIMALS
What is the role of DECOMPOSERS in an ecosystem?
recycles waste to break down waste into simpler nutrients and minerals
incl. small animals, fungi, bacteria
Define ENERGY’s role in the ecosystem
enters as light and exits as heat (constant gain and loss)
What makes up dynamic ecosystems
Recycling of chemical nutrients
flow of energy
def. DNA
chemical substance of genes
Blueprint for constructing PROTEINS
def. Genes
units of inheritance that transmit information from parent to offspring
-> controls activities and function of the cell
How is a double helix constructed
Genes are grouped into DNA molecules (chromosomes )
The Double Helix has 4 building blocks
- what are they called
- what are their letters
NUCLEOTIDES
Pair 1: A, T
Pair 2: C, G
Name 3 Domains of LIFE
Bacteria
Archaea
Eukarya
Def. Grouping Species
hierarchy of broader and broader groups
Grouping Species Order
Genus -> family -> order -> class -> phylum -> kingdom
Def. Bacteria (domains of life)
- rod shaped
- most diverse and wide spread
def Prokaryotes w/ prokaryotic cells
mostly sincle celled and microscopivc
Def. Eukarya (domains of life)
have nucleaus and internal structures (organelles)
CONTIAN
Protists (mult. kingdoms) - single celled & simple multi-celled
Kingdom Plantae - Produce food through photosythisis
Kingdom Fungi - decompose dead/waste to absorb nuntrients into cells
Kingdom Animalia - eats other organisms
Def. Intuitive reasoning
gerneralizations from large sets of data
Def. Deductive reasoning
logic flowing from genral true premis to specific results expected
organsims = cells, humans =cells, THUS humans are organisms
ARe you doning great
yes
