A root hair cell in a plant absorbs minerals that have been dissolved in water. They allow a plant to absorb these minerals by increasing the surface area; this is extremely beneficial to plants that are in dry areas.Know More
The root hair cells are delicate structures on the root of a plant which live only two to three weeks. These cells constantly form at the top of the root of the plant, so as others die, new ones take their place. This allows the root hair coverage to remain the same despite root hairs constantly dying.
The root hairs vary in size, but the lengths range in diameter from about 5 to 17 micrometers and their lengths range from about 80 to 1,500 micrometers. Root hair cells are invisible to the naked eye, but can be seen with the assistance of a microscope. The root hair cells collect nutrients from the water as well as water itself from the soil. They then carry these nutrients and water up to the rest of the plant by way of the plant's roots. The root hairs secrete acids. These acids assist solubilizing minerals into ionic form; this makes the minerals easier to carry and transport through the roots of the plant.Learn more in Biology
Water is important because the human body has a drought management system that prevents dehydration and water is the most crucial part of that system. Water also helps regulate body temperature, serves as a lubricant and is a natural headache remedy (headaches can be a sign of dehydration).Full Answer >
A diploid cell is a cell that contains a set of chromosomes from each parent so that is has two complete sets of chromosomes. Diploid cells reproduce using a process known as mitosis. This procedure creates cells that are an exact replica of the parent cell.Full Answer >
A haploid cell is one that contains only a single set of chromosomes. In humans, a haploid cell consists of 23 chromosomes. Both sperm and egg cells are haploid.Full Answer >
According to Scientific American, peptidoglycan is the substance that makes up the cell walls of bacteria. The polymer is primarily composed of amino acids and sugars. Peptidoglycan is a crucial component of bacteria, and it influences several different facets of their biology. Scientists use differences in the peptidoglycan-based cell walls to classify different bacterial species.Full Answer >
