question 5 (5 points)
listen
a prokaryotic cell is under the microscope, and a scientist is examining the proteins that help molecules and ions enter and exit the cell. what part of the prokaryotic cell is being studied under the microscope?
a) dna
b) cytoplastic membrane
c) plasma membrane

Explanation:

First Question (Cell Size Question)

Prokaryotic cells are typically 1 - 5 micrometers in size. Eukaryotic cells (including Plantae and Animalia cells, which are eukaryotic) are generally larger, often in the range of 10 - 100 micrometers. A 20 - micrometer cell fits the size range of eukaryotic cells. Plantae and Animalia are kingdoms of eukaryotes, but the question asks for the cell type (prokaryotic vs eukaryotic), so "Eukaryotic" is the best answer.

Second Question (Prokaryotic Cell Structure Question)

The plasma membrane (also called the cell membrane) in prokaryotic cells contains proteins that act as channels/transporters to allow molecules and ions to enter/exit the cell. DNA is genetic material, not involved in transport. "Cytoplastic membrane" is not the standard term; the correct term for the membrane controlling transport in prokaryotes is the plasma membrane.

Answer:

D) Eukaryotic
