What Is Biotechnology?
Biotechnology (by-o-tek-nawl-a-gee) is a big word, but it is easy to figure out what it means if you just look closer! Bio is short for biology, which is the study of all living things. Technology is another word for tools. Biotechnology then is a tool that uses biology to make new products. For example, plant biotechnology is a precise way to make seeds with special qualities. These seeds will allow farmers to grow plants that are more nutritious, more resistant to pests and more productive. Plant biotechnology is a tool for looking closer at nature to find solutions that improve the health of the Earth and its people
Biotechnology at Work
Biotechnology allows scientists to look closer at genes and make improvements in them. Your body is composed of millions of individual units called cells. Within each cell are genes that carry all of the information that allows your body to work and determines how you look. You get your genes from your parents. This is why you may look like your parents. All people, plants, and animals inherit traits from their parents through their genes. One of the first people to study how traits are passed from parents to their young was a monk in Austria named Gregor Mendel. About 150 years ago, he used plants to show how certain things such as flower size and color are passed on from the parent to the offspring. Biotechnology allows scientists to study how plants grow and how they react to the environment. As a result, scientists can now insert a specific gene into a plant that will help it adapt to its environment, make it more pest resistant, or even make it more nutritious
What Does a Cell Do?
The cell contains lots of things that help it work.
• The cell has a cover that lets some things in and keeps some things out.
• A human cell contains instructions that tell how to build humans. A plant cell contains instructions that tell how to build a plant. A bug cell contains instructions that tell how to make a bug.
• The cell has energy inside it.
• The cell has natural defenses that fight invaders such as bacteria.
Genes and DNA
Genes help determine whether your hair is straight, whether your eyes are brown, and whether you can curl your tongue. Yet genes exist in more than just people. Genes make hens white or speckled, give frogs smooth skin, and let roses smell sweet, and are found in all living things. Genes are a segment of DNA. Every cell in your body has about six feet of DNA coiled up inside it. (It’s really small!) If you put DNA under a microscope
it would look like a ladder that was twisted around and around. DNA holds the code to make and maintain proteins which help living things grow and function
Biotechnology and the Environment
Biotechnology can help farmers and the environment in many ways. Bugs and weeds are big problems for farmers. Farmers have many tools to choose from to protect their crops. Sometimes farmers use special chemicals to help control the weeds and bugs when they are really bad. Biotechnology is another option. For example, many farmers grow cotton. Some young insects, or larvae, love to eat cotton plants. To stop the larvae from feasting on cotton plants, scientists have found ways to use biotechnology to help the cotton plant protect itself from insect larvae worms. Farmers who grow these special cotton plants do not need to spray as much insecticide on their crops, and they can still grow as much or more cotton!
Weeds can be a problem for farmers too. Weeds crowd out farm crops and rob them of water, light, and nutrients they need to grow. Some farmers plow their fields to destroy these weeds, but plowing can cause soil erosion. Thanks to biotechnology, a farmer can manage the weeds without having to plow. This saves energy as well as the soil! Giving farmers more choices to control harmful bugs and weeds helps their farms and the environment.
Helping Farms Around the World
Someday, farmers could produce more food, help the environment, and produce more nutritious food. For example, the farmer in China could grow cotton and use less insecticide. The farmer in India could grow healthier rice. The farmer in the United States could grow potatoes that protect themselves from harmful insects. The farmer in Argentina could grow corn that protects itself from insects.
Biotechnology and Farming
Biotechnology is one of the many tools farmers can use to improve their crops. It could have tremendous potential for improving the environment and the food supply for people around the world. While farmers have been breeding plants to create better crops for centuries, biotechnology takes the process a giant step further. Agricultural biotechnology is a precise way to make seeds with special qualities. These seeds could allow farmers to grow plants that are more nutritious, more resistant to pests and more productive
