Have you ever wondered what makes up the tiny world inside plants and animals? Well, today we’re going on a microscopic adventure to explore plant and animal cells! You might be surprised to learn that these cells have a lot in common, but there are some key differences too.
Both plant and animal cells have a cell membrane. This is like a protective bubble that surrounds the cell, letting some things in and out. Inside the cell, there’s a jelly-like substance called cytoplasm, which holds all the tiny parts of the cell, known as organelles.
One of the most important organelles is the nucleus. Think of it as the cell’s control center. It stores all the genetic information, which is made up of DNA. This DNA contains instructions for how the cell should function and make new cells.
Both types of cells also have ribosomes, which are like little factories that make proteins. Proteins are essential for many cell functions. The Golgi bodies then package these proteins to be transported around the cell by the endoplasmic reticulum (ER). The ER is like a highway system inside the cell, moving proteins to where they are needed.
For energy, both plant and animal cells rely on the mitochondria, often called the powerhouse of the cell.
Now, let’s look at what makes plant and animal cells different. Plant cells have a cell wall made of cellulose, which helps them maintain their shape. They also have chloroplasts, which contain chlorophyll, the green pigment that helps plants make food through photosynthesis.
Plant cells have a large vacuole that stores water, nutrients, and waste. If a plant doesn’t have enough water, the vacuole shrinks, and the plant wilts. Animal cells have small vacuoles that mainly help with digestion and waste removal.
Animal cells have unique organelles called centrioles, which help with cell division. They also have lysosomes, which break down waste and defend the cell from invaders.
Let’s see what we’ve learned! Plant cells have a cell wall and chloroplasts, while animal cells do not. Plant cells have a large vacuole, whereas animal cells have small ones. Animal cells have centrioles and lysosomes, which are not found in plant cells.
Cells are fascinating and packed with all sorts of amazing structures that help them function. Now that you know more about them, you’re ready to explore the microscopic world even further!
Happy learning!
Use craft materials to build a 3D model of either a plant or animal cell. Include all the organelles you’ve learned about, like the nucleus, mitochondria, and ribosomes. Label each part and explain its function to your classmates.
Make a Venn diagram comparing plant and animal cells. List the similarities in the overlapping section and the differences in the separate sections. Share your chart with the class and discuss why these differences are important.
Write a short story from the perspective of a cell traveling through the body. Describe your journey through different organelles and explain their functions. Be creative and include challenges your cell might face along the way!
Use a microscope to observe real plant and animal cells. Draw what you see and identify the different organelles. Compare your observations with your classmates and discuss any differences you notice.
In groups, act out the roles of different organelles in a cell. Each student can be an organelle, explaining their function and how they interact with other parts of the cell. This will help you understand how cells work as a team!
Sure! Here’s a sanitized version of the transcript:

Welcome to the Cellular Learning Center!
Um, okay, but where is it? I don’t see a door.
Well, take a closer look.
I think I may have a little problem with this.
[Music]
Where are we?
Someplace really small—microscopic even!
Here at the Cellular Learning Center, we’re going to learn about plant and animal cells, and you might be surprised that there are more similarities than differences between them.
You mean I’m kind of like a plant?
Your cells share many features with plant cells, but there are important differences too.
For instance, only plant cells have cell walls on the outside, which are made of cellulose. The cell walls help the plant cells maintain their shape.
Both plant and animal cells have a cell membrane surrounding the cell. It allows some things to come in and out of the cell.
Both cells have cytoplasm, which is a jelly-like substance that contains the organelles—the tiny organs of the cell.
Both of these cells have a nucleus, which is where all the genetic material is stored. This genetic material is made of molecules called DNA, or deoxyribonucleic acid.
The nucleus contains all the information for running the cell and making new cells. The nucleus is kind of like the control center.
Every cell in an organism with a nucleus has the same genetic material or DNA, but there are many different types of cells.
How can that be?
Each type of cell is able to perform a different function because certain parts of the genetic instructions are turned off and others are turned on.
Now I see why it’s called the control center!
Only animal cells have organelles called centrioles, which aid in cell division. Animal cells have two centrioles that are perpendicular to each other, meaning they’re at right angles to each other.
Bravo!
Both plant and animal cells have ribosomes. Ribosomes are important because they help put proteins together.
The Golgi bodies take the proteins that the ribosomes make and package them so they are easier to move.
The endoplasmic reticulum, or ER for short, is the transportation network. It takes the protein packages from the Golgi bodies and moves them to where they are needed around the cell.
Some of the ER is smooth, and some is rough. The rough ER has ribosomes on the outside.
Both animal and plant cells get their energy from the mighty mitochondria.
[Music]
Plants have one really large organelle called a vacuole that fills a big part of the cell.
In a plant cell, the vacuole primarily holds water but can also hold nutrients and waste. When a plant has too little water in its vacuoles, the plant wilts.
Do animal cells have vacuoles?
Yes, but they only have very small ones. Their only roles are to digest things in the cell and get rid of cell waste.
Do you remember what the plants have that’s green and helps them with photosynthesis?
Sure, I do! It’s chlorophyll.
Smart boy!
Chlorophyll is stored in the organelles of the plant cells that are called chloroplasts.
Lysosomes are a common organelle in animal cells but aren’t found in many plant cells. They help get rid of waste in animal cells and assist with cell defense.
Boy, cells are just packed full of stuff!
Okay, let’s see how much you remember about the differences between the animal cell and the plant cell.
Sure thing!
The plant cell has a cell wall and chloroplasts; this animal cell doesn’t have those.
Second, the vacuoles in the plant cell are larger than the vacuoles in the animal cell.
And finally, the animal cell has centrioles and lysosomes, but this plant cell doesn’t.
Excellent!
It’s time we got growing!
Oh yeah, we do need to size things up.
You’re right! Here we go.

Membrane – A thin layer that surrounds and protects the cell, controlling what goes in and out. – Example sentence: The cell membrane acts like a gatekeeper, allowing nutrients to enter and waste to leave the cell.
Nucleus – The part of the cell that contains genetic material and controls the cell’s activities. – Example sentence: The nucleus is like the brain of the cell, directing all its functions and activities.
DNA – The molecule that carries the genetic instructions for life, found in the nucleus of cells. – Example sentence: DNA holds the code that determines the traits and characteristics of all living organisms.
