The cells are sensitive to a plant hormone called auxin that is produced by the leaf and other parts of the plant. |
|
The elongation of these cells break the connection between the different cell layers, allowing the leaf to break away from the plant. |
|
Living root cells passively absorb water in the absence of transpiration pull via osmosis creating root pressure. |
|
The ovalbumin and conalbumin promoters did not function in chicken fibroblasts, kidney cells, and a number of nonchicken cells. |
|
Very few ganglionic or nonganglionic cells were found in the adrenal substance. |
|
Most of the cortex was composed of fascicular cells which had nonvacuolated, nonhoneycombed eosinophilic cytoplasm. |
|
Recent publications even state that they can differentiate into nonmesodermal cells such as hepatocytes, neurons, or astrocytes. |
|
Affected animals have a reduced ability to synthesize red blood cells, which causes anemia. |
|
Cells in the salivary gland, prostate, immune system, and intestine use zinc signaling to communicate with other cells. |
|
However, viral infection is limited by the quiescence of most circulating T cells, which is nonsupportive of viral replication. |
|
Caernarfon is described as having neither drainage or fresh water and the inmates housed in tiny windowless cells. |
|
Prior to the Cambrian explosion, most organisms were simple, composed of individual cells occasionally organized into colonies. |
