Agar plates gives you a more visual view of the bacteria growth but is limited in the amount of bacteria that can grow on the plate. With broth, you won't be able to see the bacteria colonies but you will be able to grow much more of the bacteria for sampling.

The advantages and disadvantages of a broth tube culture compared to a culture on a Petri plate?
If you grow your bacteria in a broth tube you can view the oxygen requirements of the bacteria (close to the bottom, anaerobe: close to the top, aerobe)
How could you tell the bacteria were growing in the culture?
Bacteria growing on a petri dish can have more than one bacteria growing on it, but different characteristics can be seen like cilia, motility and color. To know more specifically what those other bacteria strains are, get a sample and grow it on agar by itself.
Why are there areas on the agar jelly where no bacteria are growing?
There are areas on the agar plate where no bacteria grow because that area was missed when the plate was streaked.
What would you need to do to determine whether bacteria growing on a petri plate are anaerobes?
some sense
What are the advantages of liquid culture broth?
ne advantage of bacteria is that you can use them to make foods like cheese and bread. also , some bacteria is helpful, like they live in our bodies and they help protect us from disease. other bacterias cause disease, these are the bad bacteria. the type that can make people sick and perhaps even cause people to get so sick that they can die or maybe get really sick that they feel like they want to vomit on the floor
How would you change the bacterias plate to best tell if they are ampicillin resistant?
The best test would be to take some of the bacteria growing on the LB plate and streak them on a LB/amp plate. If the bacteria are viable on the LB/amp plate, then they are resistant to ampicillin. If no bacterial colonies survive, then they were not ampicillin resistant.
When is the loop preferable for transferring bacteria?
Subculturing refers to transferring microorganisms from one medium to another. For example, bacteria growing in broth may be transferred to an agar plate.Wire loops are used to transfer microorganisms from liquid media to liquid or solid media.Needles are used for transferring microorganisms to deep tubes.
What is the procedural difference between using broth and agar as a source of bacteria for preparing a smear?
If your colonies were grown in broth, you can simply use your loop to collect loopfuls of liquid medium and smear that onto a glass slide. If they were grown on an agar plate you would have to add a few drops of water to the surface of the glass slide.
What is a petri disk?
A petri dish is a small glass plate used for, among other things, growing bacteria cultures to examine under a microscope.
Advantages of pour plate method over other methods of bacterial colony?
The purpose of the spread-plate technique is to grow and isolate colonies of bacteria. A sample of bacteria is transferred to the agar plate, an environment that provides nourishment for the bacteria to grow. The bacteria sample is applied to the agar plate which a special streaking technique that dilutes the amount of bacteria in each section of the agar plate continuously. This is because if you just swabbed the bacteria onto the plate with no special technique the colonies would grow very densely together and be difficult to study. The streaking technique gradually dilutes the amount of bacteria in each 'quadrant' of the plate, so the last quadrant should have small, isolated colonies that can be easily studied. The spread plate technique is also used for the eneumeration of aerobic microorganisms from the given sample. This can be done by serial diluting the samples, placing 0.1ml of the diluted sample in the middle of an agar plate and spreading the sample over the surface with a help of an L-rod. After the incubation rhe colonies can be counted.
