Cell Structure and Function starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Cell Structure and Function.
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 11
A student observes a cell under a microscope and notes the presence of a large central vacuole, chloroplasts, and a cell wall. Is this cell most likely from a plant or an animal?
Describe the difference between passive and active transport across the plasma membrane.
Describe the main function of the ribosome in a cell.
Describe the structure and function of the plasma membrane.
Explain the difference between rough and smooth endoplasmic reticulum.
A student observes a cell under a microscope and notes the presence of a large central vacuole, chloroplasts, and a cell wall. Is this cell most likely from a plant or an animal?
A mutation causes a cell to produce non-functional transport proteins in its plasma membrane. Predict and explain two possible effects this could have on the cell's function.
