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.
The central vacuole is a cellular organelle found in plant cells. It is often the largest organelle in the cell. It is surrounded by a membrane and functions to hold materials and wastes.It also functions to maintain the proper pressure within the plant cells to provide structure and support for the growing plant.f you've ever looked at a diagram of a plant cell, you probably noticed one organelle that stands out and is larger than all of the others. This organelle is known as the central vacuole. The central vacuole is a membrane-bound organelle containing water and other enzymes that function during the life of the plant.
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.
