Question

question 25
the diagram below shows the structure of a bacterial cell.
which of the following distinguishes this bacterial cell from eukaryotes?

dna in the bacterial cell is always in contact with the cytoplasm, and all eukaryotes have dna located inside a nucleus.
ribosomes are found in the cytoplasm of the bacterial cell, and eukaryotes do not have ribosomes.
the bacterial cell has both a cell membrane and a cell wall, and eukaryotes have only cell membranes.
the bacterial cell is a unicellular organism, and all eukaryotes are multicellular.

question 26
cells store short term cell energy when:

ions are released into the bloodstream.
the third phosphate group breaks off from an atp molecule.
a third phosphate group is bonded to an adp molecule
they break down sucrose to glucose and fructose.

Explanation:

Question 25

• Bacteria are prokaryotes. Prokaryotic cells lack a membrane - bound nucleus, so their DNA is in contact with the cytoplasm. Eukaryotic cells have a nucleus that houses their DNA.
• Option b: Eukaryotes have ribosomes.
• Option c: Many eukaryotes (e.g., plant cells) have cell walls.
• Option d: There are unicellular eukaryotes (e.g., yeast).

• ATP (adenosine tri - phosphate) stores energy. When a third phosphate group is bonded to ADP (adenosine di - phosphate) to form ATP, energy is stored.
• Option a: Ions being released into the bloodstream is not related to short - term energy storage in cells.
• Option b: When the third phosphate group breaks off from ATP, energy is released, not stored.
• Option d: Breaking down sucrose to glucose and fructose is a catabolic process for energy release, not short - term energy storage.

Answer:

A. DNA in the bacterial cell is always in contact with the cytoplasm, and all eukaryotes have DNA located inside a nucleus.
