If you observed a cell under a microscope and saw that it contained a plasma membrane cell wall and ribosomes but no other organelles what could you conclude

Complete Question:

If you observed a cell under a microscope and saw that it contained a plasma membrane, cell wall, and ribosomes, but no other organelles, what could you conclude?

A: Its an animal cell

B: its a prokaryotic cell

C: its a plant cell

Correct Option:

The given characteristics observed under a microscope concludes that its a prokaryotic cell.

Option: B

Explanation:

The unicellular organisms which constitute the youngest and most primitive living organisms on planet. Prokaryotes involve bacteria and archaeans, as arranged in the Three Domain System. Few prokaryotes are photosynthetic entities and are effective of photosynthesis, for example cyanobacteria.

They do not have a genuine nucleus, because DNA is not enclosed inside a membrane or isolated from the rest of the cell, but is coiled up in a cytoplasm region known the nucleoid. Prokaryotic cells miss organelles present in complexes of eukaryotic cells like mitochondria, endoplasmic reticules and Golgi.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

abiotic: living organisms within an ecosystem

biotic: non-living organisms within an ecosystem
