Fossils in which relicts of ancient organism activities such as feeding, movement, dwelling etc. are preserved. Chemical combination of substances produced by organism or existing in its body with minerals in the surround environment either during organism life cycle or after its death. Subdivision into kingdoms based on body plans and general morphological features. Simplest organism on planet with a single cell called prokaryotes and no hard part, as such, only occasional fossilized. Organisms with single cell and well defined nuclei called eukaryotes. Some possess hard parts and can be easily fossilized. Some with internal hard parts/ external protective structure. Organism with multi cells with cell wall containing chitin and well represented in modern biosphere. They range in size from microscopic to very large ( mushroom) The study of life of past geological periods through fossil records. Based on applications of fossil records in different fields. Organisms with multi cells capable of photosynthesis but with limited movement.
