bio Flashcards
What is LIVING?
bacteria, fungi, animal, plants, protits
fundamental properties of life (7)
cellular organization, ordered complexity, sensitivity and interaction, growth/developpement/reproduction, energy utilization, homeostasis, evolutionary adaptation
Cellular organization
-made up of at least one cell
-bounded by membrane that separates surroundings
-colonial organisms: single celled organisms that work/live tgt
-green=photosythesis
Ordered complexity
-living things are complex and highly oredered
-cells-tissues-organs-organ system-allow organism to function
Sensitivity & interaction
-organisms repsond to stimuli
-living things interact w individuals of own kind + other species
Growth, Developement & Reproduction
-reproduction (sexually or asexsually)
-genetic information transferred form parents
-genetic info controlled by development and each individual
-coded on dna molecules in chromosomes
Energy utilization
-energy required for survival
- comes from sunlight
-light energy converted into chemical energy by the plants
-convert sunlight +CO2 to glucose
-chemical energy by plant for
maintenance, growth or storage
- glucose provides the
chemical energy for Animals, Fungi and
microbes
Homostasis
- regulatory mechanisms that coordinate internal process
-ability of an organism maintain its internal environment despite conditions in the external environment
Evolutionary adaptation
-descendents of what lived long ago
-evolution is due to the effects of natural selection
the three domains
bacteria and archaea= prokaryotes (means before nucleus)
eukarya=eukaryotes
taxonomy
science of classifying organisms
allows to draw parallels between related species
individual
capacity to maintain a lineage
no two individuals are exactly the same
classifications
old: based on similarity ex. of shark and whale (subjective)
modern: based on relatedness (patterns of relationship)
The linnean hierachy (dear king phillip came over for good soup)
Domain, Kingdom, Phylum, Class. Order, Family, Genus, Species (increasing group= taxons. more species in domain)
Binomal system
2 words for the scientific name
the genus name (with capital letter) and specie name
