Cell Review

Which of the following is a characteristic of prokaryotes? 

• They have a nucleus
• They were found on Earth before eukaryotes
• The organelles in their cytoplasm are surrounded by membranes
• None of the above

Which of the following is an example of a prokaryotic cell? 

• amoeba
• brain cell
• bacterium
• liver cell

The structure that regulates what enters and leaves the cell is called

• the nucleus
• the cell wall
• the nuclear membrane
• the cell membrane

Numerous "hair-like" organelles that protrude from the surface of a cell and are packed in tight rows are called

• cilia
• flagella
• microtubules
• actin filaments

The purpose of a mitochondria is 

• to transport material from one part of the cell to another
• to package proteins so they can be stored by the cell
• as a receptor
• to release energy by "burning" glucose

In eukaryotic cells, chromosomes are found in

• smooth endoplasmic reticulum
• rough endoplasmic reticulum
• nucleus
• golgi apparatus 

All of the following are found in both animal and plant cells, except

• cell wall
• cell membrane
• mitochondria
• rough endoplasmic reticulum

At which organelle are proteins manufactured? 

• Mitochondria
• Nucleus
• Vacuole
• Ribosome

While observing a plant cell under a microscope, a student noticed some small, moving green disks. These were most likely

• leukoplasts
• mitochondria
• chloroplasts
• ribosomes

A student examines a cell under the microscope and determines that it is a eukaryote. Which structure did the student identify in order to come to this conclusion? 

• vacuole
• nucleus
• cell wall
• nucleic acids
