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 ...

Next up: Vascular tissue, which forms the circulatory system, or the veins, of the plant. Its cells are specialized for transportation, like how a subway system moves people where they need to go.

In the search for the fate-determining points of vascular stem cells, the plant scientist has developed a method for ...

Rafii. Indeed, derived from human umbilical vein cells, R-VECs are relatively durable in transplant conditions—unlike the fragile endothelial cells found in islets—and are engineered to be ...

Vascular tissue in the midrib and veins Branches of the xylem ... products of photosynthesis to other parts of the plant. Air spaces between cells within the leaf For the diffusion of gases.
