TEST UNO Flashcards
List and describe the characteristics of living organisms
order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.
Organisms are classified according
to shared features
classification systems aim to
reflect evolutionary relationships
Classification is based on
studies of morphology and anatomy
DNA sequences and proteins are used more often to
classify organisms accurately
Define species
a group of organisms that reproduce to form fertile offspring.
organisms that share recent ancestors have DNA sequences that are
similar and are closely related
binomial systems
Genus and then species
it is a formal system of naming species of living things by giving each a name composed of two parts in latin
Features of cells in living organisms
cytoplasm, cell membrane, DNA, ribosomes (for protein synthesis) and enzymes (for respiration)
main features used to classify organisms
Animals, Plants, Fungus, Prokaryote, Protoctist
Main features of organism groups
Animals:
- Vertebrates: mammals, birds, reptiles, amphibians, fish
- Arthropods: myriapods, insects, arachnids, crustaceans
Plants
- Ferns and flowering plants (dicots and monocots)
Viruses (protein coat and genetic material)
all cells except prokaryotes have
mitochondria and RER
aerobic respiration occurs in the
Mitochondrion
define tissue
distinct types of material of which animals or plants are made, consisting of specialized cells and their products
eg: connective tissue
Define organ
a part of an organism which is typically self-contained and has a specific vital function.
eg: heart
