The telomere is the protective cap of DNA on the tip of chromosomes.
You lose a small amount of these telomeres each time the cell divides. Eventually the telomeres be lost as you age. Short chromosomes because of lack telomeres are one reason aging occurs.

A root cap is a small cone of cells that protects the growing part of a root as it makes its way through the soil, the root cap is found covering the tip of a root. Right behind the root cap is the part of the root where most of the root's growth occurs.
Heating the onion root tip cells softens the cell walls and allows the acetocarmine stain to penetrate the cells. The stain then binds to the DNA in the cells, making the chromosomes visible under a microscope for easier observation and analysis in cell division studies.
The root cap originates from the calyptrogen, which is a specialized meristematic tissue located at the tip of plant roots. The cells of the calyptrogen continuously divide and differentiate to produce the root cap, which protects the root tip as it grows through the soil.
The root tip is on the bottom of the Zone of elongation and the zone of elongation is where the cells are and the cells push the zone of elongation and the root tip gets the water and sends the water through the xylem into the plant. So the root tip get the water.
Yes, the root cap is a protective tissue located at the tip of a plant root. It helps to protect the delicate meristematic cells behind it as the root pushes through the soil.
The protective layer of cells that covers the actively growing tip of a root is called the root cap. Its function is to help guide the root through the soil and protect the delicate cells of the root tip as it pushes through the soil in search of water and nutrients.
The repetitive DNA at the tip of each chromosome is called a telomere. Telomeres protect the chromosome from deterioration or fusion with neighboring chromosomes, and they shorten with each cell division. This shortening is linked to aging and disease.

Acetocarmine is a DNA specific stain like feulgen stain, so the super coiled chromosomes during different stages of mitosis present in the Onion root tip cells can be visualized perfectly by treating with this stain.

Use a Q-tip.
A root cap
The function of the root cap is to protect and cover the growing tip of the root.
A field player's crosse must be between 90cm and 110cm (between 35.5" and 43.25") tip-to-tip (including the end cap). A goalie's crosse must be between 90cm and 122cm (between 35.5" and 48") tip-to-tip (including the end cap).
