DOH data also show that asthma death rates increased with age in New York. From 2009 through 2011, children aged up to 14 had an asthma death rate of 3.5 per million residents, while the rate among New Yorkers 65 years of age and older was 36.9 deaths per million residents.
As stated earlier, the primary function of the central vacuole in plant cells is to maintain the turgor of the cell. Turgor is the pressure exerted on the cell wall by the contents of the cell.The central vacuole determines the amount of turgor based on it water content as a result of osmotic pressure.n plant cells, however, there is generally a large single central vacuole. Comprising approximately 90% of an mature plant cell, the central vacuole provides structure and support to the cell by maintaining turgor pressure, which is essentially fluid pressure that keeps the cells rigid.
A plant cell vacuole is surrounded by a single membrane called the tonoplast. Vacuoles are formed when vesicles, released by the endoplasmic reticulum and Golgi complex, merge together. Newly developing plant cells typically contain a number of smaller vacuoles. As the cell matures, a large central vacuole forms from the fusion of smaller vacuoles. The central vacuole can occupy up to 90% of the cell's volume. Vacuole Function. Plant cell vacuoles perform a number of functions in a cell including: 1  Turgor pressure control - turgor pressure is the force exerted against the cell wall as the contents of the cell push the plasma membrane against the cell wall. 2  Growth - the central vacuole aids in cell elongation by absorbing water and exerting turgor pressure on the cell wall.
