This Catalyst article explains how artificial photosynthesis could provide a useful energy supply and reduce the amount of carbon dioxide in the atmosphere. Experiments are underway in labs around the world. The aim is to use the basis of Photosynthesis to recycle the huge amounts of Carbon Dioxide being emitted...

This Catalyst article looks at the process of photosynthesis, by which plants make a range of biochemical compounds. The article explains how photosynthesis actually ties in with growth. Respiration is happening all the time in all cells in all living organisms. Taken on its own, photosynthesis adds materials to...

A Catalyst article looking at how plants develop large surface areas both in the air (leaves) and in the soil (root hairs) to get all they need from the environment. The article explores the relationship between plants and soil and looks at new research on fungi in soil and their involvement with the mineral...

From cinchona to coffee, humans have exploited properties of plants. But does our favouritism or misuse turn these plants into heroes and villains? Explore the plants that provide us with essential products, from food to medicines and insecticides.

Most people are all too familiar with the idea of animal parasites, including tape worms, ticks and lice. But did you know that plants can also act as parasites, exploiting resources from unwilling hosts? Rather than being rare anomalies, however, there are over 4000 known species of parasitic plants, with...
