Answer:

He la cells the ever first immortal human cell lines that has been  cultured in an invitro mode since 1951 to till date.

Explanation:

The name He la was first coined by the patients first and last letter of her name “Henrietta Lacks” who was suffered from severe adenocarcinoma of the cervix in 1951.The doctor who treated her removed a piece of her tumor tissue and collected tissues from other patients cultured this tissue at John Hopkins laboratory there Dr.George Gey analyze these tissue in order to find cure for cancer. In vitro cultivation of He la cells was proved to be successful with millions of her cells cultured in the laboratory which is still exists.

The He la cells contaminate other human cell lines,It was thrown a light on culture contamination  issues in many scientific field. The pros and cons of He la cells are given in a table format which is attached.

Answer:

Pros of HeLa cells:

  • HeLa cells are immortal ,easy to maintain and can be kept alive.
  • HeLa cells easily contaminate cell lines and thus can be  incorporated easily into target tissues.

Cons of HeLa cell:

  • The HeLa cells can easily contaminate cell lines and a lack of regular monitoring leads to unwanted contamination of cell lines resulting in wastage.

Explanation:

HeLa cells are immortal cells that are used in scientific and medical research. These were obtained from Henrietta Lacks , a cervical cancer patient. These cells are well known for their immortality, rapid growth and high contamination rate. These were unique cancerous cells that kept on dividing and remained alive easily.

1.Mitosis is done by your body cells. What types of cells do not undergo mitosis?

Sperm cells and egg cells do not undergo mitosis. They undergo a different process of cell division called meiosis. The difference between the two types of cell division is that mitosis result in a replication of the parent cell or identical cells. Meiosis contributes to genetic variety, meaning the resulting cells are different from the parent cell in some way.

2.Describe  ways that mitosis is important for your body.

Mitosis is important for growth. Mitosis creates new cells as you grow. If you think about it, where do we get all the extra skin, longer bones, longer hair—they result from the division of cells which create new cells.

Another way it is important is in repair. When you get a cut for example, mitosis helps by producing more cells to repair the gash that was left. New cells fill in the part that was cut. Mitosis also helps with replacing worn out cells.

3. This illustration is trying to demonstrate something that mitosis is not. In mitosis, the cells that are created are identical.

The illustration shows that one type of cell produces a different type, but it is not the case with mitosis. The resulting cells of this type of cell division is identical or twins.

4.Mitosis is just one small part of the cell cycle! Describe what would occur if cells were in mitosis more than they were in interphase.

Interphase makes up most of the cell cycle, it makes up about 90% and mitosis occurs in 10% of the whole cycle.  If cells were in mitosis more than they were in interphase that would indicate an uncontrollable and rapid growth of cells and you can get cancer.

5.When cells are dividing, it is important to understand that they have to move chromosomes equally to both cells. Based on this illustration, describe what a chromosome is made of.

Chromosomes are condensed units found in the nucleus. There are 46 chromosomes each nucleus, or each cell. Chromosomes are made up of protein and DNA. DNA stands for deoxyribonucleic acid and it carries genetic information.

6. In humans, there are 46 chromosomes. They are duplicated during interphase, which in turn duplicates the DNA as well. Chromosomes are counted based on the number of centromeres. The number of chromosomes in living organisms or species differ from each other.

What you observe when examining the onion root tip using the low-power lens
bezimeni [28]

Explanation:

Low power objective shows more field of view but does not give appreciable details about the view.

  • In the root tip of onions, the cell walls are distinctly visible and they are arranged in a rectangular mosaic pattern.
  • The nucleus stands out appreciably and it is tiny.
  • The cytoplasm is also visible.
  • Root cells do not have chloroplast since they do not take part in photosynthesis.
