Total questions: 8
Worksheet time: 9mins
A student is investigating the role of cellular transport in maintaining homeostasis. The student covers one end of a tube containing a 10% sugar solution with a semipermeable membrane. The student places the tube into a beaker that contains a 5% sugar solution. The student observes water from the beaker entering the tube. Which best describes the type of cellular transport that the student is investigating?
The student is investigating the active transport of diffusion.
The student is investigating the active transport of osmosis.
The student is investigating the passive transport of diffusion.
The student is investigating the passive transport of osmosis.

ribosomes
flagella
mitochondria
DNA
nucleus
