A scientist at the polar ice cap was studying an ice sample from 100 meters below the surface.  He noticed the cell structures of cytoskeleton, mitochondria, nucleus, cell wall and ribosomes.  What kind of organism did he find?

• animal
• bacteria
• plant
• not enough info

Some cells, such as human nerve and muscle cells, contain many more mitochondria than do other cells, such as skin cells.  Why do some cells have more mitochondria than others?

• The cells use more energy
• The cells store more nutrients
• The cells degrade more proteins
• The cells divide more frequently

The main difference between prokaryotic and eukaryotic cells is that

• prokaryotic cells are always larger
• prokaryotic cells do not have a cell membrane
• eukaryotic cells have a smaller cell nucleus
• eukaryotic cells have a more advanced cellular organization

Which is true of prokaryotic and eukaryotic cells?

• Prokaryotic cells are larger than eukaryotic cells.
• Eukaryotic cells do not have nuclei, and prokaryotic cells do have nuclei.
• Prokaryotic cells lack membrane-bound organelles, and eukaryotic cells contain membrane-bound organelles.
• Eukaryotic cells are simpler than prokaryotic cells.

Which do BOTH prokaryotes and eukaryotes contain?

• nucleus

• mitochondria

• ribosomes
