The Cell- Practice exercise 7

A student added a dye to a microscope slide with animal cells. The dye spread slowly inside the cells but didn’t leave them. The student wondered what allowed the dye to move around inside. What part of the cell allowed the dye to move inside it, and why didn’t it leave the cell? Explain your answer using the functions of the cytoplasm and cell membrane. (2 marks)
