Cell Review!! (Yellow study guide)

Which of the following are reasons someone might think that viruses are ALIVE? CHECK ALL THAT APPLY

• They are made of cells.

• They have DNA.

• Their "goal" is to reproduce.

• They evolve and adapt.

• They grow and develop.

Which of the following are reasons someone might think that viruses are NOT alive? CHECK ALL THAT APPLY

• They cannot reproduce on their own.

• They do not have a genetic code.

• They do not grow or develop.

• They are not made of cells.

• They do not engage in homeostasis.

What is NOT true about specialized cells?

• They are always unicellular.

• They have a specific job in an organism.

• An example is pollen cells in plants.

• An example is muscle cells in animals.

Which organelle acts as a cell's "post office", sorting and sending off packages of proteins?

• ribosome

• mitochondria

• smooth ER

• Golgi body

Check ALL the statements that are part of the Cell Theory.

• All living things are made of cells.

• New cells are produced independently.

• Cells are the basic units of structure and function in living things.

• All cells are microscopic.

• New cells are created from existing cells.

What is the primary function of DNA?

• It has a secret code with keys that keep viruses out of the nucleus.

• It contains the instructions for building and maintaining an organism.

• It was invented by the cops to catch bad guys.

• It contains instructions for building an organism, but it is not used once an organism is full grown.

Your DNA is your body's "instruction manual". How do your cells carry out the instructions?

• The DNA tells the ribosomes how to construct proteins that act like machines that build & maintain an organism.

• The mitochondria "read" the DNA and move around to follow the instructions.

• The DNA doesn't contain instructions.

• The nucleus reads the instructions and does the stuff.

What kind of cell is this?

• prokaryotic

• eukaryotic

• You can't tell whether it's prokaryotic or eukaryotic.

How many cells is the average human made of?

• I dunno, at least a hundo

• 120 million

• 120 trillion

• 120 gazillion

True or False: Every cell in your body has the same copy of your DNA.

• TRUE

• FALSE
