Describe the two types of cells

Ok, first you have prokaryote cells, which are simple, smaller and do not have any organelles like for example a mitochondria or vacuole. these cells are often found in unicellular organisms like bacteria and Archaea.

Eukaryote cells, on the other hand, are more complex, bigger and have different organelles (each with a specific function, in order to make the cell function properly). Organisms with eukaryote cells can be either unicellular like protists or multicellular like animals or plants.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
