Scraping with a sharp instrument to obtain cells for examination is a medical procedure called a biopsy. During a biopsy, a small sample of tissue or cells is removed from the body for laboratory analysis to help diagnose diseases such as cancer. This procedure is often done under local anesthesia to minimize discomfort.

Why are cells allowed to swim into and out of the loop's water film rather than scraping the agar surface of growth and then emulsifying cells on the slide?
Cells are allowed to swim into and out of the loop's water film because it provides a gentle environment for the cells to move freely without being disrupted or damaged. Scraping the agar surface can damage the cells and affect their viability, while emulsifying cells on the slide can disrupt their natural spatial organization, making it difficult to study their behavior.
Do cells obtain from nutrients in food?
Yes, they do
How do plant cells obtain there energy?
Chlorophyll. They get it from the sun.
What is meant by pus cells in microscopic examination of centrifuged deposit during routine urine examination?
Pus cells, also known as neutrophils, are white blood cells that indicate the presence of infection or inflammation in the urinary tract when found in urine. In a routine urine examination, the presence of pus cells may suggest a urinary tract infection, kidney infection, or some other underlying condition that requires further evaluation and treatment.
What type of cells obtain energy from cellular respiration?
All cells obtain energy from cellular respiration. Some undergo anaerobic respiration and some undergo aerobic respiration.
What instrument used to study cells?
The instrument that is used to study cells is a microscope.
What are three parts of a routine urinalysis?
Three parts of a routine urinalysis include physical examination (color, clarity, odor), chemical examination (pH, protein, glucose), and microscopic examination (red blood cells, white blood cells, bacteria).
Why are cheek cells easy to collect by scraping inside of mouth?
Cheek cells are easy to collect by scraping inside the mouth because they are loose and easily shed from the lining of the cheek. The cells are also large and flat, making them visible to the naked eye. Additionally, the collection process is non-invasive and does not require any special skills or equipment.
Why is it possible to easily collect cell by gently scraping the inside of your cheek?
Because the cells on the outer layer are dead, so they come off easily.

Can you expect to find chloroplasts in your scraping of the epithelial cells from the inside of your mouth?
No, because choloroplasts are only found in plants
Why are bacterial blood cells stained before examination?
transparent
How plant and animal cells obtain energy?
obtain energy from nucleas
What is a instrument used to see cells?
Microscope
What is an instrument that views and measures cells?
Microscope
How do living cells in the artery and vein obtain oxygen?
living cells in the arteries and veins obtain oxgyen via diffusion from the capillaries...
What part do they scrape for a pap smear?
During a pap smear, a sample of the cells of the cervix is taken. The "scraping" is more gentle than that word sounds; it is less vigorous than toothbrushing. If you remember getting a sample of cheek cells in high school biology to look under the microscope, you have a good sense of how a pap smear is taken.
