Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, similar to the way stem cells differentiate into different cell types.

By this definition, stem cells are particularly important for plant growth, because virtually all tissues of the plant descend from small groups of stem cells located in their growing apices ...
