Structure | is the way something is put together and function is the job that the structure performs. These two concepts are interrelated. |
Unicellular | organisms carry out all of the functions necessary for the organism to stay alive within a single cell. |
Multicellular | organisms are composed of many specialized cells that work together to help the organism survive. |
Autotrophs | are organisms that can make their own food, they are also known as producers |
Heterotrophs | cannot make their own food so they must eat other organisms, they are known as consumers |
Homeostasis | is the attempt of the body or a cell to maintain a constant internal environment |
feedback mechanism | a response of an organism to a given change. |
cell membrane | The function of the----------is to control what substances come into and out of the cell. |
cell wall | Plant cells have a------outside the cell membrane whose function is to shape and support the cell. |
nucleus | The nucleus of a cell directs all of the cell's activities. |
DNA | is the genetic material of the cell and it is found in the nucleus. |
Mitochondria | are organelles that produce most of the energy the cell needs to carry out its functions. |
Endoplasmic reticulum | ) is an organelle that carries proteins and other materials from one part of the cell to another. |
Ribosomes | are organelles that produce proteins inside of a cell. |
Chloroplast | is an organelle found only in plant cells that captures energy from sunlight and uses it to produce food for the cell |
Vacuole | is an organelle that is a storage area of the cell. |
prokaryotes | Bacteria cells are called prokaryotes because they do not have a nucleus. |

heredity. | is the process by which traits are passed on from parent to offspring. |
Asexual reproduction | is a reproductive process that involves only one parent and in this process the offspring is identical to the parent. |

biotic factors | 37) The living parts of an ecosystem are called the ------and the nonliving parts of an ecosystem. |
habitat | An organism’s ----- the things an organism needs to live, grow, and reproduce |
population | 39) All the members of one species in a particular area are referred to as a --------. |
community | All the different populations that live together in an area make up a --------. |
limiting factor | is an environmental factor that prevents a population from increasing. |
