to under stand the principle of bacterial isolation
so that we can dilute the consentrated bacteria (or whatever) into forming a single colony that can be idntifiied with the naked eye
alkaline zinc plating is less expensive to prepare and maintain , and it do not cause pollution as cyanide zinc plating.
there is no name for the color, but there is the "streak" of a mineral, meaning the color of its streak.
Diamonds Have No Streak AT All..
Diamond will not leave a streak on a porcelain streak plate because diamond is harder than the streak plate. It will leave a scratch on the streak plate for the same reason.
Plating out cultures is done to separate individual bacterial colonies so they can be counted, identified, or studied independently. It allows for the isolation and identification of specific microbial strains present in a mixed population.
Why is it impotant to use dry and hard agar for streaking
Streak plating and picking a single colony for the culturing in a broth.
For marketing and eye appeal
A streak plate is used to determine the streak colour of a mineral. You take the mineral and scratch it against the streak plate, and it will create a coloured streak on the plate. The streak is not always the same colour as the mineral itself.
To increases the probability that colonies of the desired organism will be isolated upon subsequent streak-plating and not crowded out by others.

Goal objective is the purpose toward which an endeavor is directed. Something that one's efforts or actions are intended to attain or accomplish; purpose; target.
The purpose of an objective is to clearly state the goal or intention of a project, task, or action. It provides direction, clarity, and focus for achieving specific outcomes.
By using streak plate technique to spread a clinical sample out on the surface of a growth medium individual types of bacteria can be isolated
Purpose: It defines the objective of the project.Scope: It is the way or the plan to get there.
