This episode details the key ingredients in fertilisers: nitrogen, phosphorus, and potassium. It outlines the chemical production of nitrogen-based fertilisers, specifically ammonium nitrate, highlighting its rich nitrogen content due to its dual sources. We explain that phosphat ...  Show more

In this episode, we look at plants and nitrogen.Plants require nitrogen to produce proteins necessary for growth. While the atmosphere is full of nitrogen gas, plants cannot directly utilise this form. Instead, they absorb soluble nitrates from the soil. Crop harvesting depletes ...  Show more

In this episode, we’ll explore homeostasis, the process organisms use to maintain stable internal conditions. We’ll discuss how this regulation is essential for responding to changes in both internal and external environments. Using enzyme function as an example, we’ll ...

In this episode, we’ll explore the distinct characteristics of prokaryotic cells and what sets them apart from more complex cell types. We’ll discuss the presence of plasmids—small DNA rings that enable genetic information exchange. We’ll examine how prokaryotic cells lack mem ...

In this episode, we look at transportation in cells. We will explain how substances move into and out of cells, highlighting three key mechanisms. Diffusion is described as the movement of particles from high to low concentration areas. Osmosis is presented as a specific type of ...  Show more

In this episode, Jamie explores the fascinating world of prokaryotic cells, focusing on their unique features such as plasmids, the absence of mitochondria and chloroplasts, and their distinctive way of storing genetic material.

This discussion is particularly valuable ...
