Functions of Components of Animal Cells Practice Exercise 3

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)

A researcher damaged the part labeled A in an animal cell below. After a while, harmful substances entered the cell, and useful materials leaked out. Name the part labeled A and explain how the damage caused these problems. (2 marks)

A science student compared two animal cells under a microscope. One had a clear nucleus, and the other did not. The cell without a nucleus was still alive but not active. Why was the cell without a nucleus still alive but not active? Explain using the role of the nucleus. (2 marks)

During an experiment, Brian accidentally damaged part B in several animal cells. After a while, the cells stopped growing and did not carry out their normal activities. Name the part labeled B. Explain how the damage caused the cells to stop growing and working properly. (2 marks)

During a science lesson, Amina looked at an animal cell under a light microscope. She noticed a round structure in the center and asked what it does. What is the name of the round structure Amina saw, and what is its main function in the animal cell?  ( 1 mark)

Two groups of scientists are studying animal cells. One group removes the nucleus from the cells, while the other leaves it intact. After some time, the first group notices their cells have stopped working and do not divide. Why did the cells without a nucleus stop functioning and dividing? Explain your answer using the role of the nucleus. (2 marks)

In a lab, cells with damaged part B were examined. The organelles were not in the right places, and chemical reactions were very slow. Name the part labeled B in the diagram below and explain how its damage led to poor organelle positioning and slower chemical reactions. (2 marks)
