| Question | Answer |
| SYMBIOSIS | Long term relationship between two organisms that helps one, and either helps, harms or does not affect the other. |
| MUTUALISM | Long term relationship between two organisms that helps both organisms |
| COMMENSALISM | Long term relationship between two organisms that helps one and does not affect the other. |
| PARASITISM | Long term relationship that helps one organisms and harms the other |
| PREDATOR-PREY | One organism (the predator) eats another organism (the prey) - NOT symbiosis |
| CELLS | Smallest unit of life. |
| TISSUES | Made up of cells working together. Two or more of these work together to make organs. |
| ORGANS | Made up of two or more types of tissue working together. These make organ systems when two or more work together. |
| ORGAN SYSTEMS | Made up of organs working together. Two or more of these working together makes an organism. |
| RESPIRATORY SYSTEM | Body system that includes the lungs, trachea, larynx, and pharynx that all work together for the purpose of breathing and exchanging carbon dioxide and oxygen. |
| CIRCULATORY SYSTEM | Organ system that is made up of all of your arteries, blood vessels, capillaries and the heart all working together to circulate blood throughout the rest of the body |
| DIGESTIVE SYSTEM | Body system that consists of the esophagus, stomach, large intestine and small intestine as its main organs to help digest your food. |
| INTEGUMENTARY SYSTEM | Organ system that is made up of all of your body's skin, is actually the largest organ in your body! Its job is to protect your body. |
| SKELETAL SYSTEM | Organ system that is made up of all of your bones to help support your body and also makes blood cells. |
| MUSCULAR SYSTEM | Body system that is made up of all of your muscles working together to help move your body. |
| ENDOCRINE SYSTEM | Body system that is responsible for regulating all of your body's hormones and metabolism. |
| IMMUNE SYSTEM | Body system that is mainly responsible for fighting disease and is helped by the lymphatic system |
| EXCRETORY (URINARY) SYSTEM | Organ system that makes urine - removes wastes as liquid and includes the kidneys |
| NERVOUS SYSTEM | Organ system that controls all other body systems, organs, etc. Includes the brain and spinal cord. |
| CELL MEMBRANE | Protective layer around the cell that controls what is allowed to enter or leave the cell. Found in both plant and animal cells. |
| CELL WALL | Protects the cell and provides structure to the cell. Usually stiff and rigid. Surrounds the outside of plant cells. |
| CHLOROPLASTS | Contain chlorophyll (makes plants green!). & MAKE FOOD by photosynthesis. Use up carbon dioxide and use sunlight. Give OFF oxygen and sugar (glucose). |
| CYTOPLASM | Clear, jelly-like substance that supports the cell and holds the organelles in place. |
| MITOCHONDRIA | Cell's Powerhouse! Provide energy. |
| NUCLEAR MEMBRANE | Controls what is allowed into and out of the nucleus. |
| NUCLEUS | Controls all activity in the cell! Holds the DNA. |
| RIBOSOMES | Cell organelle that makes Protein |
| LYSOSOMES | Organelle that disposes of and recycles cell waste. |
| VACUOLES | Storage tanks in a cell! Fluid-filled sacs that store food, water, and wastes |
| EXTINCTION | Permanent dying out of a species of organisms |
| ASEXUAL REPRODUCTION | Reproduction with only one parent that results in less variety among offspring but is faster and requires less energy than sexual reproduction |
| SEXUAL REPRODUCTION | Reproduction with 2 parents, resulting in faster evolution, more variety among offspring, but requires more energy and a mate. |
| EVOLUTION | Change in organisms over time |
| NATURAL SELECTION | the process by which organisms that are best suited to a particular environment survive and thrive. |
| MUTATION | Spontaneous change in the genetics of an organism. |
| GENE | tiny part of a chromosome that controls how a particular characteristic of an organism develops |
| ADAPTATION | any characteristic of an organism that promotes its survival in a certain environment |
| HEREDITY | passing on of genes and traits from parents to offspring |
| MEIOSIS | process of cell division that produces sperm and egg cells for sexual reproduction |
| MITOSIS | process during which the nucleus of a cell divides; responsible for growth and repair of injuries |
| GENOTYPE | tells the genes inherited by an individual for a specific trait |
| PHENOTYPE | tells the physical characteristics inherited by an individual for a specific trait |
| PUNNETT SQUARE | used to predict the genotypes produced from the genotypes of two parents |
| HOMOZYGOUS | genotype where both genes are identical (both recessive or both dominant |
| HETEROZYGOUS | genotype where both genes are different (one recessive and one dominant) |
