Plant Cell Parts and Function

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.

Proteins are produced at which cellular structures?

• nuclei
• ribosomes
• mitochondria
• chloroplasts

Some prokaryotes and eukaryotes have a cellular structure called a flagella.  What is the purpose of the flagella?

• to transport molecules across the cell membrane
• to propel the cell through liquid
• to collect food for the cell
• to tell the cell the direction of a food source

• Lack membrane-bound organelles

How are prokaryotes and eukaryotes similar?

• They both contain membrane-bound organelles.
• They both have cell membranes.
• The both have nuclei.
