Life Science Test
| Question | Answer |
|---|---|
| Dichotomous Key | An aid that is used to identify organisms and that consists of the answers to a series of questions |
| Chromosomes | In a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA |
| Animalia | A kingdom made up of complex, multi-cellular organisms that lack cell walls, can usually move around, and quickly respond to their environment |
| Golgi Body | The cell organelle that helps make and package materials to be transported out of the cell |
| Lipid | A type of biochemical that does not dissolve in water |
| Cell Membrane | A phospholipid layer that covers a cell's surface and acts as a barrier between the inside of a cell and the cell's environment |
| Cell | In biology, the smallest unit that can perform all life processes |
| Fungi | A kingdom made up of nongreen, eukaryotic organisms that have no means of movement, reproduce by using spores, and get food by breaking down substances in their surroundings and absorbing the nutrients |
| Classification | The division of organisms into groups, or classes, based on specific characteristics |
| Eukaryote | An organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include animals, plants, and fungi, but not archaebacteria or eubacteria |
| Eubacteria | A kingdom that contains all prokaryotes except archaebacteria |
| Endoplasmic Reticulum | A system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids |
| Decomposer | An organism that gets energy by breaking down the remains of dead organisms or animal wastes and consuming or absorbing the nutrients |
| Lysosome | A cell organelle that contains digestive enzymes |
| Life science | The study of living things |
| Homeostasis | The maintenance of a constant internal state in a changing environment |
| Carbohydrate | A class of energy-giving nutrients that includes sugars, starches, and fiber |
| Controlled Experiment | An experiment that tests only one factor at a time by using a comparison of a control group with an experimental group |
| Prokaryote | An organism that consists of a single cell that does not have a nucleus |
| Consumer | An organism that eats other organisms or organic matter |
| Law | A summary of many experimental results and observations |
| Producer | An organism that can make its own food by using energy from its surroundings |
| Hypothesis | An explanation that is based on prior scientific research or observations and that can be tested |
| ATP | A molecule that acts as the main energy source for cell processes |
| Plantae | A kingdom made up of complex, multicellular organisms that are usually green, have cell walls made of cellulose, can't move around, and use the sun's energy to make sugar by photosynthesis |
| Archaebacteria | A kingdom made up of bacteria that live in extreme environments |
| Cell Wall | A rigid structure that surrounds the cell membrane and provides support to the cell |
