ClassX Video Lessons Youtube Channel Next Generation Science Observing the Cell Membrane of an Animal Cell
Have you ever wondered what makes up the outer layer of a cell? In this article, we’re going to explore the fascinating world of animal cells, focusing on their cell membranes. Let’s dive in and learn something cool!
Cells are the building blocks of all living things. They are like tiny factories that keep plants and animals alive. Some cells are so small that you need a microscope to see them, but did you know that some eggs, like chicken eggs, are actually giant single cells? That’s right! These eggs are big enough to see without any special tools.
Chicken eggs have a hard outer shell made from a material called calcium carbonate. This shell protects the egg from getting damaged. But what happens if we remove this shell?
We can dissolve the shell by placing the egg in vinegar. Vinegar is an acid that reacts with the calcium carbonate, causing the shell to disappear. After a few hours, the shell will be completely gone, and you’ll be left with just the cell membrane.
The cell membrane is the outer layer of the egg once the shell is removed. It’s translucent, which means you can see through it a little bit. It’s also a bit squishy and delicate. This membrane is very important because it holds everything inside the cell together and controls what goes in and out of the cell.
Without the hard shell, the cell membrane is the only thing protecting the inside of the cell. If it gets damaged, the cell could break or not work properly. That’s why the cell membrane is so important for keeping the cell safe and healthy.
Did you know that all living things, from tiny bacteria to giant elephants, have cell membranes? It’s true! This special layer is essential for life.
Thanks for learning with us! We hope you enjoyed discovering more about cell membranes. Remember, there’s always something new to learn about the amazing world of science!
Egg Experiment: Try the egg experiment at home with an adult’s help. Place a raw egg in a cup of vinegar and watch what happens over a few days. Observe how the shell dissolves and leaves behind the cell membrane. Write down your observations each day. What does the egg look like? How does it feel? Discuss with your family why the cell membrane is important for the egg.
Cell Membrane Role Play: Imagine you are a cell membrane. Create a short skit or role play with your friends or family where you act as the cell membrane. Think about what you need to do to protect the cell and control what goes in and out. What would you say to a harmful substance trying to enter the cell? How would you let nutrients in?
Everyday Cell Membranes: Look around your home or school and find objects that act like cell membranes. For example, a plastic bag keeps food fresh by controlling what goes in and out, just like a cell membrane. Make a list of these objects and explain how they are similar to a cell membrane. Share your findings with your class or family.

In this video, we will observe plant and animal cells, focusing on the cell membrane of an animal cell.
Did you know that chicken eggs and the eggs of most animals are actually giant single cells? To protect them from the environment, these cells have a hard outer shell made from calcium carbonate.
We can dissolve the shell by placing the egg in vinegar. After a few hours, the shell will be completely dissolved.
[Music]
The outer part of the egg is the cell membrane.
[Music]
The cell membrane is translucent, a bit squishy, and delicate.
[Music]
Without the protection of the hard outer shell, the cell could become damaged or broken more easily.
Thanks for watching! See you next time.
