Student exploration paramecium homeostasis answer key

Home Find Gizmos Lesson Info. Observe how a paramecium maintains stable internal conditions in a changing aquatic environment. Water moves into the organism by osmosis, and is pumped out by the contractile vacuole. The concentration of solutes in the water will determine the rate of contractions in the paramecium.

Student Exploration: Paramecium Homeostasis Vocabulary: adaptation, cell mouth, cilia, concentration, contractile vacuole, food vacuole, homeostasis, hypertonic, hypotonic, macronucleus, micronucleus, oral groove, osmosis, paramecium, solute, solution, solvent Prior Knowledge Questions Do these BEFORE using the Gizmo. The images show red blood cells RBCs in three different solutions. Which image shows RBCs in normal blood plasma? Which image shows RBCs in pure water? Which image shows RBCs in a very salty solution? What do you think is happening in images A and C? One of the challenges for a paramecium is to maintain a stable size and shape.

Student Exploration: Paramecium Homeostasis Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: adaptation, cell mouth, cilia, concentration, contractile vacuole, food vacuole, homeostasis, hypertonic, hypotonic, macronucleus, micronucleus, oral groove, osmosis, paramecium, solute, solution, solvent. Which image shows RBCs in normal blood plasma? Which image shows RBCs in pure water? Which image shows RBCs in a very salty solution? In image A the cell is shrinking because the water is going out.

Thanks, got it! We will moderate it soon! Respond to the questions andprompts in the orange boxes. A thermostat is a device that regulates the temperature inside a building. What does a thermostat do if it gets too cool? What does a thermostat do if it gets too hot? How do our bodies sometimes act like a thermostat? This process is called homeostasis. The Human Homeostasis Gizmo allows you to explore how the human body stays at a nearly constant temperature indifferent conditions.

Water moves into the organism by osmosis, and is pumped out by the contractile vacuole. The concentration of solutes in the water will determine the rate of contractions in the paramecium. Explore the processes of photosynthesis and respiration that occur within plant and animal cells. The cyclical nature of the two processes can be constructed visually, and the simplified photosynthesis and respiration formulae can be balanced. Observe the steps of pollination and fertilization in flowering plants. Help with many parts of the process by dragging pollen grains to the stigma, dragging sperm to the ovules, and removing petals as the fruit begins to grow.

You can change the amount of light each plant gets, the amount of water added each day, and the type of soil the seed is planted in. Observe the effect of each variable on plant height, plant mass, leaf color and leaf size. South Africa. If the solute concentration in the water is low hypotonic solution , does water move into or out of the paramecium? Click Reset, and repeat this procedure for all of the listed concentrations. Learn More about Growing Plants. Flag for inappropriate content. Infer: Water moves into and out of the paramecium by a process called osmosis. Why do you think this is the case?
