Explanation:

An agar plate is a Petri dish containing agar as a solid growth medium supplied with nutrients (i.e., an enriched medium), which enable to culture different microbes ranging from fungi to bacteria. Colony morphology is a widely used approach to describe the unique features of bacteria colonies growing on agar media. These colony features include, among others, shape (round, circular, punctiform, irregular), elevations/depressions (convex, concave, flat), textures (dry, moist, crusty, dull, shiny, mucoid, friable, rough), colors (cream, white, purple, gray, red, green, yellow, blue), etc.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
