A greenhouse with a perovskite solar cell rooftop led to faster growth and larger leaves in radicchio seedlings ...

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 ...

and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction (Figure 1).

Vascular cambium produces xylem (wood) and phloem, and together with the cork cambium, which produces a protective layer at the surface called phellem (cork), they provide thickness to plant organs.
