What else can I help you with?
Is the most common form of bacterial cells bacilli?
No, the most common form of bacterial cells is cocci, which are spherical in shape. Bacilli are rod-shaped bacteria, which are also common but not as prevalent as cocci.
Are all cell the same shape?
Not at all. They can range from most plant cells that are generally rectangular, to skeletal muscle cells that are generally long and cylindrical, to epithelial and nerve cells that have no defined shape, to amoeboids that are constantly changing their shape. Almost any shape you can imagine, you can probably find a cell that almost matches it.
What is the major differences between a bacterial cell and the cell of other organisms?
All bacterial cells do not have a nucleus but the cells of other animal have nucleus which is usually spherical or oval in shape inside it there are chromosomes that form a dense tangle referred to as chromatin.
What is the influence of the pH on the gram reaction in gram staining?
In what regard? You need heat in order to heat fix the bacterial cells to the slide. This adheres cells to the slide. Otherwise, the bacterial cells would wash off the slide during the Gram staining process. If you leave the slide in the Bunsen burner too long, then you can distort the bacterial cell shape and size and also have other artifacts appear on the slide that are not bacterial cells.
Why does penicillin not affect human cells?
This is essentially because bacterial cells and human cells are very different. Both bacterial and human cells use chemicals called enzymes to build their walls. Penicillin is the right chemical "shape" to chemically stick to part of the bacterial enzyme. When it does this, it stops the bacterial enzyme from working properly and this makes the bacterial cell walls weak. The weakened cell wall cannot withstand the outside pressure, it breaks up and the bacterial cell dies. Human cells are made by different types of enzymes with a different chemical shape that penecillin is unable to stick to so it cant stop the human enzymes from working. The human cell walls are thus unaffected by it and they remain strong.
How does an epidermal cells shape allow it to protect the body?
The shape supports the cell and does not allow anything to pass through it.
Is used to describe the shape and arrangement of the individual bacterial cells?
bacterials cells only have one sell just to let you know :)

Is it true bacterial cells do not have a nucleus?
Bacterial cells do have a nucleus. Basically all cells have a nucleus! Bacteria cells are just a different shape like plant cells. If cells didn't have a nucleus they wouldn't be able to work properly!
What Nerve cells have a shape that allow them to do?
Quickly deliver and receive messages.

What cell structure found in plant and bacterial cells but not animal cells called?
The cell structure found in plant and bacterial cells but not animal cells is the cell wall. This rigid structure provides support and protection to the cell, maintaining its shape and preventing it from bursting in a hypotonic environment.

How do some animal cells set shape without a cell wall?
Some cells (Eukaryotes in particular) have an organelle known as a cytoskeleton, this organelle governs the shape of a cell and the position of other organelles.

What do bacterial cells and animal cells have in common?
All of these are living cells. They all have DNA as genetic material, cytoplasm and a cell membrane. They vary in size, vary in shape and are measured in micrometers. They all form an important part of our ecosystems.
