Confidence votes 14. ANSWER:There are many reasons that a plant wilts. Lack of water in the plant's cells (lower turgidity) reduces its ability to remain rigid or erect. Other reasons are diseases, bacteria or fungi that block or reduce the plants ability to transfer water through the body of the plant.
(June 2011). The nephron (from Greek Î½ÎµÏÏÏÏ - nephros, meaning kidney) is the basic structural and functional unit of the kidney. Its chief function is to regulate the concentration of water and soluble substances like sodium salts by filtering the blood, reabsorbing what is needed and excreting the rest as urine.omposed of a glomerulus and the Bowman's capsule, the renal corpuscle (or Malpighian corpuscle) is the beginning of the nephron. It is the nephron's initial filtering component. The glomerulus is a capillary tuft that receives its blood supply from an afferent arteriole of the renal circulation.
The other cells, neurons, act as the communicators of the nervous system. Neurons receive information, integrate it, and pass it along. They communicate with one another, with cells in the sensory organs, and with muscles and glands. Each neuron has the same structure:1  Each neuron has a soma, or cell body, which is the central area of the neuron.2  It contains the nucleus and other structures common to all cells in the body, such as mitochondria. Axons send information to other neurons, to muscle cells, or to gland cells. 2  What we call nerves are bundles of axons coming from many neurons. 3  Some of these axons have a coating called the myelin sheath. 4  Glial cells produce myelin, which is a fatty substance that protects the nerves.
