At the most basic level of classification, cells can be either prokaryotic or eukaryotic.
Prokaryotic cells are only bacteria or archaea, eukaryotic cells are fungi, protists, plants and animals.
The key difference is that eukaryotes have a true nucleus and membrane-bound organelles. Prokaryotes lack a true nucleus and membrane-bound organelles. Prokaryotes are simple and are only ever unicellular.
Organic matter in the soil is significant in making hummus. Hummus, on the other hand, is hygroscopic and therefore holds water and nutrients in the soil and alleviates leaching. This makes these factors available to plants for growth and promotes vegetation growth.
