What Do You Know About Africa?
What do you think of when you hear the word AFRICA?
Do you think of safaris? And villages?

What is Biotechnology?
Perhaps you have heard of the term biotechnology and wondered what it is. You may think you know already – after all, the parts that make up the word are very familiar: bio + technology. You have seen the first part of the word in biology, antibiotics, all sorts of words. It comes from Greek bios, which means ‘life’.
As for technology, it is not just about computers and smartphones. Technology is the practical use of knowledge to create useful things and solve problems. You might like to think of it as tech-knowledge-y. So, taking it one step further, biotechnology is about using biology in technology.
We talked to Alessandra Iscaro, a biotechnology researcher at the University of Florence, Italy, and she explained to us what it is all about.
Green and Growing: The Life of a Seed
As you know, there is a vast number of different kinds of plants growing all over the world, from snowy slopes to Amazon rain forests to dusty deserts: plant life is everywhere. So how does it all work? Lets start with seeds.
The Life of a Seed
Picture a seed – I am sure you have all seen them. It will have a hard outer shell to protect it. When it has found the right conditions of warmth and moisture, this shell will crack or split as a root pushes its way out to take hold in the soil. Then the plant will start to grow and a shoot will make its way upwards, with the root growing down, to draw moisture from the ground and provide some balance for the plant, keeping it firm in its place.
Just like you and me, plants need food to grow. Their food is very different from ours, of course! Here’s what they do: the leaves draw water up from the roots, through the stem, and they also soak up sunlight and air. These three things combine to make food in the leaves, where it is stored. Now think of an onion. It is formed to store the food for the plant.
