Team uses nanoparticles to deliver genes into plant chloroplasts

MIT researchers have developed a new genetic tool that could make it easier to engineer plants that can survive drought or resist fungal infections. Their technique, which uses nanoparticles to deliver genes into the chloroplasts ...

Growing the tallest is not always the best option

Plants need sunlight to feed and grow. Without light, photosynthesis, the reaction by which the plant chloroplasts convert atmospheric CO2 and water into sugars and oxygen, cannot take place. In some situations, such as in ...

A new way to transfer energy between cells

Researchers from the Catalonian Institute of Bioengineering (Instituto de Bioingeniería de Cataluña) and the Seville Chemical Research Institute (Instituto de Investigaciones Químicas de Sevilla) have described a new method ...

Scientists debunk potential link to crop cold tolerance

When temperatures drop, the enzyme Rubisco that fuels plant growth and yield gets sluggish. Many crops compensate by producing more Rubisco; however, scientists speculated that some crops may lack space in their leaves to ...

Chloroplast

Chloroplasts (English pronunciation: /ˈklɒrəplæsts/) are organelles found in plant cells and other eukaryotic organisms that conduct photosynthesis. Chloroplasts capture light energy to conserve free energy in the form of ATP and reduce NADP to NADPH through a complex set of processes called photosynthesis.

Chloroplasts are green because they contain the chlorophyll pigment. The word chloroplast (χλωροπλάστης) is derived from the Greek words chloros (χλωρός), which means green, and plastis (πλάστης), which means "the one who forms". Chloroplasts are members of a class of organelles known as plastids.
