Organelle is a specialized unit within a cell that has a specific function.
A hypothesis is a vital part of not only the scientific method but in experimenting, whether or not you are familiar with the method. A hypothesis is important, because by stating your perspective and percieving on the topic you are able to build on that, despite how much it may be wrong or how much it may be right. It's the first step to forming a final conclusion. With a hypothesis you can fully build and construct the final results and conclusion to any experiment or topic you are focusing on.

Explanation:
In the viable plate count method, a measured volume of a culture is evenly spread across an agar surface and incubated. Each <u>colony </u>represents one <u>cell </u>from the original sample.
Explanation:
A viable count is the number of colony forming units (cfu) of microbes per gram or per milliliter of the sample, or cfu/gm or cfu/ml.
In order to find whether the cells counted is viable or not, methods like plate-count method, membrane-filter methods are used. These tests allow the visible cells to grow and multiply to check the viability.
The plate count method is done by growing the microorganisms like bacteria on a plate in a nutrient medium or substrate like the agar surface. The bacteria will grow into colonies and will be visible to the naked eye.
Each colony unit is counted and each unit in a colony represents a single cell of the bacteria or any microorganism cultured and counted.
The counting is done by various methods like hemocytometers, streak plate etc.
