U1L5 Quiz Homeostasis and Cell Processes

Master cell processes and homeostasis with this engaging quiz!

1. Place the following into either active or passive transport Passive Transport Does not require energy Molecules move from high to low concentrations diffusion osmosis Active Transport Does require energy Molecules move from a low area of concentration to a high area of concentration endocytosis exocytosis 2.Match the type of transport with the appropriate definition Osmosis The diffusion of water from high to low Diffusion movement of molecules from high to low Active Transport The cell needs to use energy to move particles from low to high concentration Cell Membrane Separates cell's Cytoplasm from the outside environment. This is where particles can enter and leave the cell 3.Use the word bank to fill in the blanks within the short reading. Homeostasis and Cell FunctionFor a cell to function normally, a stable state must be maintained inside the cell. For example, the concentration of nutrients must be kept within a certain range for the cell to survive. The process of maintaining stable conditions inside a cell (or an entire organism) is homeostasis. Homeostasis requires adjustments, because conditions are always changing both inside and outside the cell. The processes of passive and active transport play important roles in maintaining homeostasis. By moving substances into and out of cells, they keep conditions within normal ranges inside the cells and the organism as a whole. 4. Which cell organelle is MOST responsible for helping the cell maintain homeostasis by diffusion? mitochondria nucleus cell membrane 5.Homeostasis is necessary for a cell to survive. What is the definition of homeostasis? elimination of wastes division of cells maintenance of a stable internal environment process by which energy from the sun is used to make food 6. Mitosis is a cell division. What is the reason that human skin cells frequently undergo mitosis? to get energy for the body to prevent bruises on the body to replace dead or damaged skin cells 7.Cells must be able to perform certain functions in order to survive. Which of the following must all cells do to survive? obtain energy absorb wastes continue growing 8. What two "materials" are needed for photosynthesis? oxygen and carbon dioxide carbon dioxide and water glucose oxygen Click the words to fill in the blank. 9. Photosynthesisis a food-making process.10. Glucoseis used during cellular respiration.11. Cellular respirationis turning food into energy.12. Mitosisis when cells divide. Fill in the blank (Matthew 5:3) “Blessed are the poor in spirit, for theirs is the kingdom of heaven.”
