bio process chapter1

QuestionAnswer
lifes hierarchy of organization Biosphere-ecosystem-community-population-organism-organ system- organ- tissue-cell- organelle- molecule
biosphere conists of all the environments on earth that support life
ecosystem consists of all the organisms living in a particular area as well as all the nonliving elements of the environment with which organisms interact.
community entire array of organisms inhabiting a particular ecosystem.
population individual species living in an area.
organism individual living thing.
organs work together in performing specific functions
tissues each organ is made up of several different tissues. each with a specific function and made up of a group of similar cells
cell makes up tissues. a cell is separated from its invironment by a boundary called membrane
organelle membrane bound structure that performs a specific function in the cell
molecule is a cluster of atoms held together by chemical bonds.
emergent properties of the whole result from the specific arrangement and interactions of the component part
system biology goal is to construct models for the dynamic behavior of biosphere to the complex molecular machinery of a cell
prokaryotic smaller of the two types of cells. lacks a cell nucleus and membrane-bound organelles
euaryotic ex. plants, animals, fungi. cell that is subdivided by internal membranes into many different functional comparments or organelles, including the nucleus that houses the cells DNA
system biology goal is to construct models for dynamic behavior of whole bio systems, ranging from the functioning of the biosphere to the complex molecular machinery of a cell
every cell.... is enclosed by a membrane that regulates the passage of materials b/t cell and its surroundings and uses DNA as its genetic info
7 common properties of organisms order, regulation, growth & development, energy processing, response to the environment, response to the environment, reproduction, evolution.
order all living things exhibit complex organization.
regulation mechanisms to maintain an organisms internal invironment (homeostasis)
growth and development genes control pattern of growth and development.
energy processing organisms take in energy and transform it to perform all life's activities. ex. ATP --> respiration.
domain bacteria most diverse and widespread prokaryotes. unicellular
domain Archea prokaryotes that live in earths most extreme environments.
kingdom protists (domain eukarya) eukaryotes, single-celled, ex. algae.. makes own food for photosynthesis.
protozans (domain eukarya) animal-like protists (b/c they eat other organisms)
kingdom plantae (domain eukarya) consists of plants, that produce their own food, have cells with rigid cell walls made of cellulose.
kingdom fungi decomposers (domain eukarya) molds, yeast, fungi.
kingdom animalia (domain eukarya) obtain food by ingestion, motile and made of cells that lack rigid walls.
discovery science verifiable observations and measurements are the data of this type of science. uses inductive reasoning.
inductive reasoning kind of reasoning derives general principles from a large number of specific observations.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
