Cards in this deck (34)
- 1What is the definition of the cell?A cell is the smallest structural and functional unit of an organism.
- 2What is a Prokaryotic Cell?Is a type of cell that only covers bacteria and unicellular organisms.
- 3What is an Eukaryotic Cell?Is a cell that is multicellular and unicellular and covers mostly animals.
- 4What is an Organelle?Is any of a number of organized or specialized structures within a living cell.
- 5What is a Cell Membrane?Is the semipermeable membrane surrounding the cytoplasm of a cell.
- 6What is the Cytoplasm?Is a goo substance that every part of the cell floats in.
- 7What is the Nucleus?Is the center and main control of the cell.
- 8What is a Ribosome?Are the protein builders or protein synthesizers of the cell.
- 9What is the Rough Endoplasmic Reticulum?Is a system of membrane that possesses ribosomes.
- 10What 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.
- 11What is a Mitochondria?Rod-shaped organelle that converts energy in food molecules to energy the cell can use to carry out its function.
- 12What 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.
- 13What is a Vacuole?A sac-like organelle that store water, food and waste.
- 14What is the Chloroplast?A plastid that contains chlorophyll and in which photosynthesis takes place.
- 15What is a Cell Wall?A rigid layer that surrounds the cells of plants and some other organsims.
- 16What is Chemical Digestion?Breaking down of foods into their building blocks.
- 17What is Mechanical Digestion? Where does it take place?tearing or grinding food into smaller pieces.
Usually takes place in mouth and stomach. - 18What do the Salivary Glands do?They make saliva to break down food.
- 19What are Enzymes?A type of protein that speeds up a chemical reaction in a living thing.
- 20What is the Esophagus?A muscular tube that connects the mouth to the stomach.
- 21What is the Epiglottis?A flap of tissue that seals off the windpipe and prevents food from entering the lungs.
- 22What is the stomach?An organ in the form of a muscular pouch where food is broken down, located in the abdomen.
- 23what is the liver?It processes the nutrients absorbed from the small intestine.
Makes bile and is the largest. - 24What is the Gall Bladder?It stores the bile.
- 25what is the Pancreas?It stores insulin, digestive enzymes are produced, aid in breathing down carbohydrates, proteins, and fats.
- 26What is Absorption?The process by which nutrient molecules pass through the wall of the digestive system into the blood.
- 27what is the small intestine?It absorbs the nutrients and is below the stomach.
- 28What is the Large intestine?it absorbs water from the remaining indigestible food matter and transmit the useless waste material from the body.
- 29What 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 - 30What is digestion?The process by which your body breaks down into small nutrient molecules that can be absorbed by cells.
- 31What are the 2 types of digestion?Chemical and Mechanical (physical)
- 32What is Saliva?The fluid released from glands in the mouth that plays an important role in both mechanical and chemical digestion.
- 33What is peristalsis?Waves of smooth muscle contractions that move food through the esophagus toward the stomach.
