- 1SYMBIOSISLong term relationship between two organisms that helps one, and either helps, harms or does not affect the other.
- 2MUTUALISMLong term relationship between two organisms that helps both organisms
- 3COMMENSALISMLong term relationship between two organisms that helps one and does not affect the other.
- 4PARASITISMLong term relationship that helps one organisms and harms the other
- 5PREDATOR-PREYOne organism (the predator) eats another organism (the prey) - NOT symbiosis
- 6CELLSSmallest unit of life.
- 7TISSUESMade up of cells working together. Two or more of these work together to make organs.
- 8ORGANSMade up of two or more types of tissue working together. These make organ systems when two or more work together.
- 9ORGAN SYSTEMSMade up of organs working together. Two or more of these working together makes an organism.
- 10RESPIRATORY SYSTEMBody system that includes the lungs, trachea, larynx, and pharynx that all work together for the purpose of breathing and exchanging carbon dioxide and oxygen.
- 11CIRCULATORY SYSTEMOrgan 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
- 12DIGESTIVE SYSTEMBody system that consists of the esophagus, stomach, large intestine and small intestine as its main organs to help digest your food.
- 13INTEGUMENTARY SYSTEMOrgan 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.
- 14SKELETAL SYSTEMOrgan system that is made up of all of your bones to help support your body and also makes blood cells.
- 15MUSCULAR SYSTEMBody system that is made up of all of your muscles working together to help move your body.
- 16ENDOCRINE SYSTEMBody system that is responsible for regulating all of your body's hormones and metabolism.
- 17IMMUNE SYSTEMBody system that is mainly responsible for fighting disease and is helped by the lymphatic system
- 18EXCRETORY (URINARY) SYSTEMOrgan system that makes urine - removes wastes as liquid and includes the kidneys
- 19NERVOUS SYSTEMOrgan system that controls all other body systems, organs, etc. Includes the brain and spinal cord.
- 20CELL MEMBRANEProtective layer around the cell that controls what is allowed to enter or leave the cell. Found in both plant and animal cells.
- 21CELL WALLProtects the cell and provides structure to the cell. Usually stiff and rigid. Surrounds the outside of plant cells.
- 22CHLOROPLASTSContain chlorophyll (makes plants green!). & MAKE FOOD by photosynthesis. Use up carbon dioxide and use sunlight. Give OFF oxygen and sugar (glucose).
- 23CYTOPLASMClear, jelly-like substance that supports the cell and holds the organelles in place.
- 24MITOCHONDRIACell's Powerhouse! Provide energy.
- 25NUCLEAR MEMBRANEControls what is allowed into and out of the nucleus.
- 26NUCLEUSControls all activity in the cell! Holds the DNA.
- 27RIBOSOMESCell organelle that makes Protein
- 28LYSOSOMESOrganelle that disposes of and recycles cell waste.
- 29VACUOLESStorage tanks in a cell! Fluid-filled sacs that store food, water, and wastes
- 30EXTINCTIONPermanent dying out of a species of organisms
- 31ASEXUAL REPRODUCTIONReproduction with only one parent that results in less variety among offspring but is faster and requires less energy than sexual reproduction
- 32SEXUAL REPRODUCTIONReproduction with 2 parents, resulting in faster evolution, more variety among offspring, but requires more energy and a mate.
- 33EVOLUTIONChange in organisms over time
- 34NATURAL SELECTIONthe process by which organisms that are best suited to a particular environment survive and thrive.
- 35MUTATIONSpontaneous change in the genetics of an organism.
- 36GENEtiny part of a chromosome that controls how a particular characteristic of an organism develops
- 37ADAPTATIONany characteristic of an organism that promotes its survival in a certain environment
- 38HEREDITYpassing on of genes and traits from parents to offspring
- 39MEIOSISprocess of cell division that produces sperm and egg cells for sexual reproduction
- 40MITOSISprocess during which the nucleus of a cell divides; responsible for growth and repair of injuries
- 41GENOTYPEtells the genes inherited by an individual for a specific trait
- 42PHENOTYPEtells the physical characteristics inherited by an individual for a specific trait
- 43PUNNETT SQUAREused to predict the genotypes produced from the genotypes of two parents
- 44HOMOZYGOUSgenotype where both genes are identical (both recessive or both dominant
- 45HETEROZYGOUSgenotype where both genes are different (one recessive and one dominant)
