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?

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. In image C the cell is breaking because of too much water. Gizmo Warm-up A paramecium is a one-celled organism that lives in ponds and other bodies of water. One of the challenges for a paramecium is to maintain a stable size and shape. On the Paramecium Homeostasis Gizmo, turn on the Show labels checkbox. Try to determine the function of each of the labeled structures. Through which two structures do you think Cell mouth food enters the paramecium? Oral groove. Which two structures contain DNA?

Water solute concentration. Therefore, according to the properties of osmosis, water will naturally move from inside the cell to outside, and there is no need for a contractile vacuole.

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.

Take 10 seconds to Sign up! I would like it explain in your own words, but i In image A and C H2O is either leaving or entering the red blood cells. This is because the water moves in and out of the paramecium by a process called osmosis. Introduction: Every organism needs to maintain stable internal conditions—a process known as homeostasis —in order to survive. In which situation is the paramecium in danger of swelling up and bursting? Water moves into the organism by osmosis, and is pumped out by the contractile vacuole. Animals Animals.
