However, there are exceptions to the size limitation. Some fiber cells in the jute plant can reach lengths of two meters. These long cells are the reason why jute was a favored material for ropes before synthetic materials were developed. Also, mycoplasma, are only 0.1 m in diameter. But generally, cells tend to stay in the 10 m range.
Cells carry out metabolic processes through their cell walls.
Metabolic process are all the chemical processes that occur at the cellular level that keep a cell, and therefore the whole organism alive. Protein synthesis, respiration, digestion and waste removal are examples of metabolic processes. Although a cell is small, it has a complex molecular composition. Molecules can range in size from a few nanometers to a few micrometers. Molecules inside and outside the cell, such as carbohydrates, enzymes, hormones, nucleic acids must interact and react together.
