Heart, stomach, spleen, skin, brain, kidneys, bladder, lungs…. What are the functions of the following Organ Systems? • Integumentary • Skeletal • Muscular • Respiratory •Protection and homeostasis •Protection and support •Movement •Delivers oxygen and removes waste List three examples of cells in the body. Muscle cell, neuron, blood cell, sperm, egg, skin cell What is cell differentiation? A process in which cells become different types of cells. What is the basic shape of DNA? Double helix or twisted ladder What are the sides of the DNA molecule made of? Sugar (deoxyribose) and phosphate What are the steps or rungs of the DNA molecule made up of? Nitrogen bases adenine, thymine, cytosine & guanine What does DNA stand for? Deoxyribonucleic acid Label the diagram. 2 4 3 5 1 6 7 1.Phosphate 2.Sugar (deoxyribose) 3.Nitrogen bases 4.Guanine 5.Adenine 6.Cytosine 7.Thymine A disk formed between the two new nuclei of a plant cell that is dividing. cell plate The longest phase of the cell cycle in which a cell is preparing to reproduce interphase A section of DNA that has information about a specific trait of an organism. gene What is DNA and What is RNA? DNA: deoxyribonucleic acid; genetic material located in the nucleus of a cell RNA: ribonucleic acid; plays an important role in the production of proteins. Groups of tissues that work together and perform one or more functions. organ
