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 ...

This episode focuses on the role of photosynthesis in greenhouse farming. 

It highlights how lighting and heating can be manipulated to boost photosynthetic rates, thus increasing crop yield. However, farmers face a crucial economic decision</str ...

This episode explores the historical shift in drug discovery from natural sources to synthetic production. 

Initially, many essential medicines like Digitalis and Aspirin were derived directly from plants, highlighting the importance of botanical resources</stron ...

Liz looks at thermoregulation for your GCSE Biology exam. In this episode, she will look at how the changes to body temperature are detected and what the responses to these temperature changes are. Liz looks at the role of receptors and blood vessels in thermoregulation. Perfe ...
