All living organisms are made up of cells - they are the basic building blocks of life. There are two important categories of cells: plant cells and animal cells. In this video we look at animal cells in more detail. Animal cells are the...

Sally’s never-ending field trip continues. This time, they’re exploring the bustling city of Zoo York. Perhaps she’ll travel for the rest of year 11, only returning home for a hot meal and special occasions. This lesson will examine the...

Seeking excitement, Sally embarks on a self-guided ghost tour of Zoo York’s ‘abandoned tunnels’. Will she spot anything spooky? This lesson will finalise our crash course on the structure of animal cells, focusing on components...

The cells in your body are like computer software: they're "programmed" to carry out specific functions at specific times. If we can better understand this process, we could unlock the ability to reprogram cells ourselves, says...

Even though it might seem like our bodies are on autopilot, there is a whole lot happening inside us to keep things moving. In this episode of Crash Course Biology, we’ll learn that our cells are in constant communication, reminding each...

The video is discusses the differences between eukaryotic and prokaryotic cells. It begins by defining what eukaryotic and prokaryotic cells are and then goes on to explain the structures and functions of each type of cell. The lesson...

The video discusses the different types of cells found in living organisms and their structures. It compares and contrasts the overall structures of eukaryotic, animal, plant, and prokaryotic cells. The video explains the internal...

Compares and contrasts prokaryote cells and eukaryote cells before exploring organelle structures and functions! Video includes the modern cell theory and plant vs. animal cell comparisons. See table of contents by expanding video...

Join Pinky and Petunia of the Amoeba Sisters in a review game video! This video provides clues for the viewer to guess the cell organelle or structure before revealing it. As a bonus, towards the end of the video, you'll have the...

Biology can be pretty dry. You’re stuck in a classroom studying a textbook full of boring definitions and complicated diagrams... That’s why we’re going on a field trip with Sally! She’s visiting a floating city in the Pacific Ocean –...

Biology can be pretty dry. You’re stuck in a classroom studying a textbook full of boring definitions and complicated diagrams... That’s why we’re going on a field trip with Sally! She’s visiting a floating city in the Pacific Ocean –...

Did you know that some organisms exist of just one cell? These simple organisms, like amoeba, are unicellular. They depend on simple diffusion for life They are usually too small to be visible to the naked eye, like bacteria, and so we...

Ok, we are ready to investigate the immune system! So where do we start? Rather than starting on the big objects, like the organs in the lymphatic system, the best way to dive in is to briefly discuss the different types of cells that...

Explore the cell cycle with the Amoeba Sisters and an important example of when it is not controlled: cancer. Table of Contents: 00:00 Intro 1:00 Cell Growth and Cell Reproduction 1:42 Cancer (explaining uncontrolled cell growth) 3:27...

Explore some examples of specialized plant and animal cells with the Amoeba Sisters! Video explains how specialized cell structure suits their function. Table of Contents: Intro 00:00 Specialized Cell Defined 0:26 Animal and Plant Cells...

We compare plant cells and animal cells under a microscope to see how they differ. Cheek cells are dyed with methylene blue to make the observations possible. Biology - Cells And DNA - Learning Points. Almost all cells are invisible to...

Every living thing on our planet, from plants to animals, is made up of cells. Cells are the building blocks of life, but what are they and how do they work? Biology - Cells And DNA - Learning Points. All cells have vital genetic...

Journey inside the cell to see how the cell membrane acts as both a barrier and an entrance. How does it take in nutrients while keeping out potentially damaging molecules? Biology - Cells And DNA - Learning Points. The cell membrane...

This video explains the concept of cell specialization and differentiation. The narrator discusses how cells differentiate to become specialized for their unique functions within an organism. The differences in differentiation between...

Red Blood Cells are unique cells. And in this video, we talk about their structure and function. Learn about their biconcave shape, the missing organelles, details about hemoglobin and gas exchange.

Leukocytes or White Blood cells are very important cells in your blood. They function primarily as the defenders of the body, protecting your body when things go wrong or when foreign invaders like bacteria or parasites try to cause...

Erythrocytes a.k.a. Red Blood Cells help us transport oxygen throughout the body. But what happens when they don’t work the way they should? Let's find out.

The video discusses how different types of animal and plant cells are specialized for various functions. The video highlights sperm cells, nerve cells, muscle cells, root hair cells, sieve tubes, and flame cells to illustrate how each...

Explore the unique features of plant cells compared to animal cells. Learn about the specialized structures such as vacuoles, cell walls, and chloroplasts that distinguish plant cells. Understand how these features contribute to the...
