| What is the definition of the cell? | A cell is the smallest structural and functional unit of an organism. |
| What is a Prokaryotic Cell? | Is a type of cell that only covers bacteria and unicellular organisms. |
| What is an Eukaryotic Cell? | Is a cell that is multicellular and unicellular and covers mostly animals. |
| What is an Organelle? | Is any of a number of organized or specialized structures within a living cell. |
| What is a Cell Membrane? | Is the semipermeable membrane surrounding the cytoplasm of a cell. |
| What is the Cytoplasm? | Is a goo substance that every part of the cell floats in. |
| What is the Nucleus? | Is the center and main control of the cell. |
| What is a Ribosome? | Are the protein builders or protein synthesizers of the cell. |
| What is the Rough Endoplasmic Reticulum? | Is a system of membrane that possesses ribosomes. |
| What is the Golgi Apparatus? | An organelle in a cell that receives proteins and other new formed materials from the E.R., packages them, and distributes them to other parts of the cell. |
| What is a Mitochondria? | Rod-shaped organelle that converts energy in food molecules to energy the cell can use to carry out its function. |
| What is a Lysosome? | A cell organism which contains chemicals that breaks down large food particles into smaller ones and that can be used by the rest of the cell. |
| What is a Vacuole? | A sac-like organelle that store water, food and waste. |
| What is the Chloroplast? | A plastid that contains chlorophyll and in which photosynthesis takes place. |
| What is a Cell Wall? | A rigid layer that surrounds the cells of plants and some other organsims. |
| What is Chemical Digestion? | Breaking down of foods into their building blocks. |
| What is Mechanical Digestion? Where does it take place? | tearing or grinding food into smaller pieces. Usually takes place in mouth and stomach. |
| What do the Salivary Glands do? | They make saliva to break down food. |
| What are Enzymes? | A type of protein that speeds up a chemical reaction in a living thing. |
| What is the Esophagus? | A muscular tube that connects the mouth to the stomach. |
| What is the Epiglottis? | A flap of tissue that seals off the windpipe and prevents food from entering the lungs. |
| What is the stomach? | An organ in the form of a muscular pouch where food is broken down, located in the abdomen. |
| what is the liver? | It processes the nutrients absorbed from the small intestine. Makes bile and is the largest. |
| What is the Gall Bladder? | It stores the bile. |
| what is the Pancreas? | It stores insulin, digestive enzymes are produced, aid in breathing down carbohydrates, proteins, and fats. |
| What is Absorption? | The process by which nutrient molecules pass through the wall of the digestive system into the blood. |
| what is the small intestine? | It absorbs the nutrients and is below the stomach. |
| What is the Large intestine? | it absorbs water from the remaining indigestible food matter and transmit the useless waste material from the body. |
| What are the 3 main functions of the Digestive System? | -breaks down food into molecules the body can use -molecules are absorbed in the blood and carried throughout the body -wastes are eliminated from the body |
| What is digestion? | The process by which your body breaks down into small nutrient molecules that can be absorbed by cells. |
| What are the 2 types of digestion? | Chemical and Mechanical (physical) |
| What is Saliva? | The fluid released from glands in the mouth that plays an important role in both mechanical and chemical digestion. |
| What is peristalsis? | Waves of smooth muscle contractions that move food through the esophagus toward the stomach. |
