Unlike a prokaryotic cell, a eukaryotic cell has the ability to

• store all genetic information in DNA.

• capture and use energy from the sun.

• have relationships with other organisms.

• combine into multicellular organisms.

Which cell organelle is most directly involved with the bonding of amino acids and the production of proteins?

• cell wall

• ribosome

• mitochondrion

• endoplasmic reticulum

What function does ATP carry out in living things?

• ATP is used to both capture and to transfer cellular energy.

• ATP helps to identify DNA start sequences for transcription.

• ATP helps to maintain the needed fluidity of cell membranes.

• ATP allows protein to fold and coil for cellular processes

How are prokaryotic and eukaryotic cells different?

• Eukaryotes contain a nucleus; prokaryotes do not contain a nucleus.

• Prokaryotes contain a nucleus; eukaryotes do not contain a nucleus.

• Eukaryotes contain a cell membrane; prokaryotes do not contain a cell membrane.

• Prokaryotes contain a cell membrane; eukaryotes do not contain a cell membrane.
