Bacteria are easier to observe on a plate. The bacteria look in the plate compared to the broth as with very clear morphological structures including margin and elevation point.
On a plate as opposed to in a broth, bacteria are easier to see. While it is simpler to observe bacteria in a clear container and we are able to see their morphology (size, shape, elevation, and margin), when looking at bacteria in broth, we can only tell if the bacteria is turbid or if there is flocculent microbial growth at the bottom of the nutrient broth tube.
A unique bacterial cell or group that has repeatedly split is represented by each separate colony. Because they were kept together, the resultant cells have amassed to create a noticeable area. Most bacterial colonies are often round in form and appear white or creamy yellow in color.
