Amoeba is different from plant cell because the plant cell is eukaryotes whereas Amoeba is prokaryotes. so plant cell are more similar in size and are typically rectangular or cube shaped and An amoeba has no definite shape
Well-sorted sediments have grains of similar size, and are the result of much sediment transport and earth processes which segregated the sediment by depositing different size fractions in different places.
