All living cells require water and nutrients. If an organism is a single cell or if its body is only a few cells thick, water and nutrients are easily moved through the organism by diffusion. However, diffusion is generally too slow for even small...

Vascular tissue is a complex tissue found in vascular plants, meaning that it is composed of more than one cell type. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There...

Human organs are being designed and grown in laboratories using biopolymer scaffolds and matrices, as a result of the astonishing developments in tissue engineering and regenerative therapies. But the next step, implantation of the new organs into humans, may be hindered by basic...

The hypersensitive response (HR) is a programmed cell death that is commonly associated with plant disease resistance. A novel lesion mimic mutant, vad1 (for vascular associated death1), that exhibits light conditional appearance of propagative HR-like lesions along the vascular system was identified. Lesion formation...
