All cells have these two characteristics:

a contain DNA in the nucleus and have a plasma membrane
b produce a cell wall outside of the plasma membrane
c contain mitochondria and chloroplasts
d have a plasma membrane and ribosomes in the cytoplasm

d have a plasma membrane and ribosomes in the cytoplasm

Well, you know what they say, all cells need their "mem-brain" to keep everything together, just like we need our brain cells to entertain people with jokes. And as for ribosomes, they're like the cell's little protein factories, working hard to make everything run smoothly. So, yeah, all cells have a plasma membrane and ribosomes in the cytoplasm. They're the dynamic duo of the cellular world!

The correct answer is:

d) have a plasma membrane and ribosomes in the cytoplasm

The correct answer is d) have a plasma membrane and ribosomes in the cytoplasm.

To arrive at the correct answer, let's break down the characteristics given:

a) contain DNA in the nucleus and have a plasma membrane: This characteristic describes eukaryotic cells, which have a distinct nucleus where DNA is housed. The plasma membrane surrounds the cell and controls the movement of substances in and out of the cell.

b) produce a cell wall outside of the plasma membrane: This characteristic describes cell walls, which are found in prokaryotic cells (such as bacteria) and some eukaryotic cells (such as plant cells). However, not all cells have cell walls, so this option is not correct for all cells.

c) contain mitochondria and chloroplasts: These are organelles found in eukaryotic cells. Mitochondria are responsible for energy production, and chloroplasts are responsible for photosynthesis. However, not all cells contain these organelles, so this option is not correct for all cells.

d) have a plasma membrane and ribosomes in the cytoplasm: This characteristic is true for all cells. All cells have a plasma membrane, which surrounds the cell and controls the movement of substances. Additionally, all cells have ribosomes, which are responsible for protein synthesis, located in the cytoplasm.

Therefore, the correct characteristic that all cells possess is d) have a plasma membrane and ribosomes in the cytoplasm.

a contain DNA in the nucleus and have a plasma membrane
