Practice Osmosis with authentic MYP MYP Biology exam questions for both SL and HL students. This question bank mirrors Paper 1, 2, 3 structure, covering key topics like cell biology, genetics, and ecology. Get instant solutions, detailed explanations, and build exam confidence with questions in the style of MYP examiners.
Which of the following best defines osmosis?
During the process of plasmolysis in a plant cell, what specifically is observed happening to the cell's structure?
In the sequence of events leading to a plant's wilting, which step occurs immediately before the leaves start to droop?
Which of the following best explains why the movement of water in osmosis is described as 'net' movement?
What is the primary cause of soil becoming hypertonic to a plant's roots?
In terms of molecular concentration, why does water move towards a solution with a high solute concentration during osmosis?
The cell membrane is described as a 'passive' sieve during osmosis. What does the term 'passive' specifically imply in this context?
Why do doctors use a saline solution for intravenous (IV) drips instead of pure water?
True or False: In a hypertonic solution, the plant cell membrane pulls away from the cell wall in a process called plasmolysis.
True or False: Protein molecules are generally much larger than glucose molecules, making it even less likely for them to pass through a cell membrane during osmosis.
