Microfossile often present in petroleum producing formationsare those of__________?
Correct answer: A. Diatioms
- A. Diatioms
- B. Heliozoans
- C. Radiolarians
- D. Foraminiferans
Explanation
Diatom frustules are siliceous and resist decay, allowing them to become abundant microfossils in sedimentary and petroleum-associated formations. Foraminiferans are also important marine microfossils, so they may seem plausible, but this question specifically identifies the silica-preserved diatom remains.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
