Tree Farming: Why change trees genetically

The video discusses genetic engineering in trees, focusing on reducing lignin content to improve cellulose and paper production. Lignin acts as a glue between cellulose cells, providing stability to trees. Concerns arise about the environmental impact of transgenic trees compared to genetically altered plants like corn. Experiments on poplar trees involve introducing foreign genes, with Sweden investing in information technology for forestry. Research on species jumping and genetic safety is conducted in natural settings to assess potential risks.

What is the primary goal of reducing lignin content in trees through genetic engineering?

• To enhance the stability of trees

• To facilitate easier processing of cellulose and paper

• To improve the taste of tree fruits

• To increase the height of trees

Which tree species is primarily used in the genetic engineering experiments discussed?

• Oak

• Pine

• Poplar

• Maple

What is Sweden's current focus in forestry technology?

• Genetic modification of trees

• Networked harvesting machines for automation

• Increasing the workforce in forestry

• Reducing the use of fertilizers

What is the main concern regarding transgenic trees in natural environments?

• They might cause species jumping

• They could lead to deforestation

• They could produce less oxygen

• They might not grow as fast as expected

What is the purpose of the German Institute for Research into Forestry's experiments with transgenic trees?

• To improve the taste of tree fruits

• To create new species of trees

• To determine if foreign genes spread to the environment

• To increase the height of poplar trees
