Cell Membrane and Transport starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Cell Membrane and Transport.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 7
A cell is placed in a solution with a higher concentration of water than inside the cell. What will happen to the cell?
A cell uses energy to move a substance from an area of low concentration to high concentration. What type of transport is this?
A scientist observes that a cell is using energy to move molecules out of the cell. What process is likely occurring?
Describe how the cell membrane helps protect the cell.
