cells&organelles

To enter or leave a cell, substances must pass through

• golgi apparatus 
• ribosome
• nucleus 
• plasma membrane 

Bacterial cell are prokaryotic; in comparison to a typical eukaryotic cell they would

• be smaller 
• have a smaller nucleus 
• lack a plasma membrane 
• have a greater variety of organelles 

You would expect a cell with an extensive Golgi apparatus to

• make a lot of ATP
• secrete a lot of material 
• move actively 
• perform photosynthesis 

Which of the following correctly matches an organelle with its function?

• mitochondrion.... photosynthesis 
• nucleus... cellular respiration 
• central vacuole... storage
• lysosome... movement

Of the following organelles, which group is involved in manufacturing substances needed by the cell?

• lysosome, vacuole, ribosome
• ribosome, Rough ER, smooth ER
• vacuole, Rough ER, Smooth ER
• smooth ER, vacuole, ribosome 

A cell has mitochondria, ribosomes, smooth and rough ER, and other parts. Based on this information, it could not be

• cell from a pine tree
• grasshopper cell
• yeast (fungus) cell
• bacterium

The electron microscope has been particularly useful in studying bacteria, because

• electrons can penetrate tough bacterial cell walls
• bacteria are so small
• bacteria move so quickly they are hard to photograph 
• their organelles are small and slowly packed together 

Cell fractionation is the most appropriate procedure for preparing ____ for study.

• cells without a functional cytoskeleton 
• isolated organelles 
• basic macromolecules
• bone and other similar cells which are situated within a mineral framework

Which of the following clues would tell you whether a cell is prokaryotic or eukaryotic?

• presence or absence of a rigid cell wall
• whether or not the cell is partitioned by internal membranes
• presence or absence of ribosomes
• whether or not the cell contains DNA

Sara would like to film the movement of chromosomes during cell division. Her best choice for a microscope would be a

•  light microscope, because of its resolving power.
• transmission electron microscope, because of its great resolving power.
• light microscope, because the specimen is alive.
• transmission electron microscope, because of its magnifying power.
