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...

We use coloured agar cubes to see how different shapes change the rate of diffusion. The cubes are made using sodium hydroxide and phenolphthalein indicator to give them a pink colour. When these are added to hydrochloric acid, the...

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...

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...

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...

Explore the basic structure and functions of plant and animal cells, the fundamental units of living organisms. Learn about the similarities and differences between plant and animal cells, including the roles of the cell membrane,...

Delve into the microscopic world of viruses, learning about their structure, how they differ from living organisms, and their methods of infecting host cells. Understand the components of a virus, including nucleic acids (DNA or RNA),...

In this video, Jonathan from The Institute of Human Anatomy delves into the world of antibiotics and their impact on the human body. He explains what they are, explores their benefits, allergies, and discusses the potential risks that...

In this video, Jonathan from the Institute of Human Anatomy discuss the anatomy of skin pigmentation, and how it can vary across the body.

Dr. Forrester describes how plants inherit traits of similar plants through DNA. She also discusses the experiments of Gregor Mendel by evaluating his studies on genetics.

We've covered macrophages and dendritic cells, so let's move on to neutrophils. These are the most abundant white blood cells, and they act as the first line of defense in innate immunity. How do they form, and what do they do...

Jay Gargus (UC Irvine) describes the importance of combining genetic and biophysiological principles to penetrate the true nature of disease.

Plant and Animal Cells explores plant and animal cells by identifying important structural components and functions of each.
