Microbiologists use the gram stain to aid in the identification of bacteria. What is the major difference between gram-positive and gram-negative bacteria?

Answers

Answer 1
Answer:

The major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.

Gram-positive bacteria do not contain an outer plasma membrane, whereas Gram-negative bacteria have a lipid-rich outer plasma membrane.

This outer plasma membrane contains lipopolysaccharide (LPS) in addition to phospholipids and proteins.

Moreover, Gram-positive bacteria are also surrounded by thick layers of peptidoglycan.

In conclusion, the major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.

Answer 2
Answer:

Answer:

Microbiologists use the gram stain technique to identify the gram-positive and gram-negative bacteria on the basis of the composition of their cell wall.

The major difference between the cell wall of gram-positive bacteria and gram-negative bacteria is that in gram-positive bacteria peptidoglycan is the major component which makes gram-positive cell wall whereas in gram-negative bacteria their cell wall has a thick outer layer of Lippo polysaccharide and a thin inner layer of peptidoglycan.

So in gram stain gram-positive cell wall retains the crystal violet because of the thick peptidoglycan layer and appears violet and gram-negative appears pink as it lacks the outer thick peptidoglycan layer.

The stems cells make new cells by the process of cell division and the new cells continuous to divide and continue to grow and specialize into new cells that tends to replace themselves.

  • They can also self replicate and differentiation is the process by which they divide and change in the formation.
  • For cells to deicide they must meet the right conditions and this involves the succession of proliferation to specialization.

Final answer:

Stem cell division is the process of mitosis that produces two identical daughter cells, which can then either remain as stem cells or differentiate into specialized cells. Specialized cells have specific functions in complex organisms.

Explanation:

In stem cell division, stem cells undergo the process of mitosis to produce two identical daughter cells. These daughter cells can either remain as stem cells or differentiate into different types of specialized cells. Stem cell differentiation is the process by which stem cells develop into distinct cell types with specific functions. In complex organisms like humans, specialized cells play crucial roles in various physiological processes, such as carrying oxygen in red blood cells or transmitting signals in nerve cells.

oogamates

oogamates is known to be a large non- motile gametes that contain a reserve material which is being used by the developing zygote that is formed when the sperm fuses with such gametes. Thus, gametes can be defined as a set of dissimilar chromosomes formed through mitosis.

Scientists investigated two types of violet plants. One was found more frequently in shade, the shade violet. The other was found more frequently in sunny places, the violet. Which violet is which? Give a reason for your choice.

Answers

Answer:

Violet plant with small leaves found in sunny places while violet plant with big leaves are found in the shade.

Explanation:

In our planet, the plants though they cannot move like animals and humans, they can adapt themselves to the surroundings and the environment. Plants have the ability to adjust themselves in the varied climate and landscape around themselves.

Almost all the plants need sun light or sun energy to grow and make their own food. Some plants grow well in direct sun light  while some others grow in shades.

In the context, scientist discovered two varieties of violet plants out of which one grows frequently in the sunny places whereas the other found frequently in the shade.

Now the violet plant which have small leaves than the other violet plant are found more frequently in the sunny places as these plants get direct sun light or energy all through the day to make their food. While the plant which have adapted to make food in the shade having large leafs so they can absorb more of sun's energy and make their food. They are found in the shade.
