Animal cells can be distinguished from plant cells easily because of which of the following?

• Animal cells have mitochondria and plant cells do not.

• Plant cells have lysosomes and animal cells do not.

• Only plant cells have centrioles around their nucleus.

• Only plant cells have large central vacuoles and cell walls.

Jared observes a cell in biology lab with the light microscope. The cell has the following structures: nucleus, cell wall, and chloroplast. Identify the type of cell that Jared is observing.

• animal

• plant

• fungus

• bacteria

Hair and nails are mostly filled with the protein keratin. Keratin is produced by keratinocytes. The cells must contain several of which of the following organelles?

• mitochondria

• endoplasmic reticulum

• ribosomes

• lysosomes

Carrie observes an electron micrograph of a cell during biology lab. The cell has a flagellum, ribosomes, cell wall, and no apparent nucleus. Which of the following is likely true of the cell that Carrie is observing?

• The cell also contains mitochondria.

• The presence of the organelles proves that the cell is eukaryotic.

• The cell is a plant because of the cell wall.

• The cell is prokaryotic.

Look at the cell organelles. Which of these organelles transports organic molecules that are responsible for providing structure and controlling cellular processes?

• endoplasmic reticulum

• mitochondria

• ribosomes

• Golgi apparatus

Which of the following best describes the function of the Golgi apparatus?

• It modifies and transports proteins after the ribosome makes them.

• It manufactures lipids and then transports them to a new location.

• It manufactures proteins and nucleic acids using the DNA code.

• It modifies lipids and proteins and places them into packages.

Due to energy needs, muscle cells usually have a lot of which organelle?

• ribosomes

• mitochondria

• Golgi apparatus

• lysosomes

A fossilized cell is discovered, and evidence suggests it reproduced on its own and had DNA, but a membrane did not enclose its DNA. Which type of organism would this most likely be?

• prokaryote
• eukaryote
• plant cell
• animal cell

CHALLENGE QUESTION: Which of the following provides evidence for the hypothesis that prokaryotes evolved before eukaryotes.

• prokaryotes are more complex

• prokaryotes have no nucleus and fewer genes

• eukaryotes are multicellular which makes them simpler

• prokaryotes grow into eukaryotes

Where is the DNA found in a eukaryotic cell? 

• floating around in the cytoplasm 
• in the nucleus
