Which of the following choices incorrectly matches a tool that biologists use to study cells with a type of experiment the tool might be used for?
A.Transmission electron microscopy (TEM) to study the distribution of organelles in a living cell B.Whether or not the cell is partitioned by internal membranesC.The components of the ribosomes are first assembled in the nucleus. The nucleus contains the instructions for protein synthesis by the ribosomes.D.Direct physical contact among all the organelles of the EM system is needed to permit movement of lipid and protein components among the organelle. |

A. Transmission electron microscopy (TEM) to study the distribution of organelles in a living cell |
| |
|
Which of the following clues would tell you whether a cell is prokaryotic or eukaryotic? |
|
whether or not the cell is partitioned by internal membranes |
| |
|
Which statement(s) correctly describe(s) the relationship between the nucleus and ribosomes of a eukaryotic cell? |
|
The components of the ribosomes are first assembled in the nucleus. The nucleus contains the instructions for protein synthesis by the ribosomes. |
| |
|
Which statement describes a process that is not part of the function of the endomembrane system? |
|
Direct physical contact among all the organelles of the EM system is needed to permit movement of lipid and protein components among the organelle. |
| |
|
A cell has formed a food vacuole as it ingested a food particle. Which is not likely to occur with the breakdown of that food particle? |
|
Enzymes for the breakdown of the food are delivered to the food vacuole from the cytoplasm. |
| |
|
Mitochondria are found in _____. |
|
both plant and animal cells |
| |
|
Which of the following functions is not likely to be associated with the cytoskeleton in eukaryotic cells? |
|
determining which proteins are synthesized by the cell |
| |
|
Which statement about extracellular structures (plant cell walls and the extracellular matrix of animal cells) is incorrect? |
|
Extracellular structures are barriers that prevent small molecules from entering or leaving the cell. |
| |
|
Which of the following correctly matches an organelle with its function? |
|
central vacuole ... storage |
| |
|
If one is trying to understand cellular function, what is the most important limitation associated with the study of isolated organelles? |
|
In a functioning cell, organelles are not independent of each other. |
