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.
Plant Cell Vacuoles. Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth. Many plant cells have a large, single central vacuole that typically takes up most of the room in the cell (80 percent or more). Vacuoles in animal cells, however, tend to be much smaller, and are more commonly used to temporarily store materials or to transport substances. The central vacuole in plant cells (see Figure 1) is enclosed by a membrane termed the tonoplast, an important and highly integrated component of the plant internal membrane network (endomembrane) system.
