15 Questions
Which process is responsible for the wilting of a plant when its cells lose turgor?
Osmosis
What happens to microorganisms when high sugar concentration is applied in food preservation?
They die
How does salting fish and beef preserve them?
By killing microorganisms
What is the purpose of tying knots at the ends of the visking tubing in the osmosis experiment?
To prevent leakage
What is the control in the osmosis experiment using visking tubing?
Distilled water
What happens to the mass of the visking tubing containing concentrated sucrose solution after being suspended in distilled water?
It increases
What is the purpose of replicating the osmosis experiment or cross-referencing results with other groups?
To validate the results
What does the increase in turgidity of the visking tubing containing concentrated glucose solution demonstrate?
Osmosis
Which of the following is true about diffusion?
It is affected by temperature, concentration difference, and distance
Which process involves the movement of water molecules from a region of higher water concentration to a region of lower water concentration?
Osmosis
Which substances can freely pass through selectively permeable membranes?
Water, oxygen, and carbon dioxide
What is the pressure exerted by the cytoplasm and vacuole against the cell wall of a plant called?
Turgor pressure
Which of the following examples demonstrates diffusion?
Transpiration of water vapor through stomata of leaf
Which factor does NOT affect the rate of diffusion?
Mass of substance
When is a plant cell considered turgid?
When water cannot enter the cell by osmosis
Test your knowledge on plant wilting, food preservation techniques, and osmosis experiments in biology. Learn about the effects of turgor loss on plants, the impact of high sugar concentration on microorganisms, and how salting preserves fish and beef. Understand the role of visking tubing and knots in osmosis experiments, along with the concept of control and mass changes in such experiments.
