What is a discrete set?

A set which is made up only of isolated points is called a discrete set.


What is a discrete graph?

A graph composed of isolated points.


How can you tell colonies on agar gel plate are discrete?

Discrete colonies on an agar gel plate can be identified by their clear separation from one another, with a defined boundary around each colony. They typically appear as individual, well-isolated clusters of cells, often showing distinct shapes, sizes, and colors. Additionally, the lack of merging or overlapping between colonies indicates that they are discrete and not competing for resources. Observing these characteristics helps in distinguishing individual microbial species in mixed cultures.


What do you call a set of numbers with an exact number of points?

This is called a discrete set (all points isolated) or a finite set. Finite sets are always discrete.


What factor contributes to the difference in the appearance of isolated versus crowded colonies?

1. The factors that contribute to the differences in appearance of isolated vs crowed colonies are: 1. Availability of nutrients, where colonies are crowed the bacteria will be in competition for nutrients and because of this there can be a reduction of size and shape also growth can also be stunted whereas in isolated colonies the nutrients is readily available with no competition for nutrients. 2. space, isolated colonies have more space to grow as compared to crowded colonies and 3. If there is contamination in a crowded colony the texture will be very difficult to determine however texture can be viewed in isolated colonies so contamination is a factor.


Will isolated colonies of bacteria always be in the fourth sector on the streak plate?

No, isolated colonies of bacteria may not always be in the fourth sector on the streak plate. The placement of isolated colonies can vary depending on factors such as the distribution of bacteria on the plate and the streaking technique used.


What is a graph of isolated points called?

A graph of isolated points is called a discrete graph. In this type of graph, each point represents a distinct value or data point, and there are no connections or edges between them, highlighting their individual significance. Discrete graphs are often used to represent data sets where values are separate and not continuous.

Will isolated colonies always be in the second sector on the streak plate?

No. It depends on the number of bacteria present in the initial sample. If the number of bacteria in the initial sample are limited, you may get isolated colonies in the first streak. If the number of bacteria in the sample are high, it may take several streaks before the sample is diluted to the point where isolated colonies are evident.

Why restreak isolated colony?

Restreaking an isolated colony helps to obtain a pure culture by separating individual bacterial cells and preventing contamination. It also allows for further characterisation of the colony and ensures reproducibility in future experiments.
