transport vesicles
Which of the following structures is essential for the successful operation of the Endo membrane system?
Presence of a cell wall
Which of the following would distinguish a bacterial cell from an animal cell?
An Archean
A certain cell has a sense nucleons region, ribosomes, but no membrane-enclosed organelles. Based on this info it could be
10 to 100 micrometer
A normal size for a typical eukaryotic cell is
Golgi apparatus
A researcher made an interesting observation about a protein made by the rough endoplasmic reticulum and eventually used to build a cells plasma membrane. The protein in the membrane was actually slightly different from the protein made in the endoplasmic reticulum. The protein was probably altered in the
The proteins are folded, then packaged for transport to the Golgi apparatus
How are cell surface proteins exported out of the cell?
Smooth Endoplasmic Reticulum
In muscle cells the ______ is/are specialized for the storage and release of calcium.
Chloroplast
Many researchers think that the first eukaryotic cells consumed the organic compounds needed for life-sustaining functions. Given this information which of the following organelles most likely appeared last in eukaryotic cells?
ribosome, rough ER, smooth ER
Of the following organelles which group is involved in manufacturing the substances needed by the cell?
The plant Cell wall provides a more rigid structure
One function of the central vacuole in plant cells is facilitating cell growth: the central vacuole absorbs water and increases in size, expanding the volume and size of the plant cell while doing so. Animal cells, however, do not grow by this method. What is an essential difference between animal and plant cells that could explain how a plant cell can withstand this expansion of the central vacuole?
Several million
Pancreatic cells produce large amounts of protein. About how many ribosomes would you expect there to be in a pancreatic cell?
Rough ER
Pancreatic cells secrete a lot of proteins. With this in mind which of the following organelles would be abundant in pancreatic cells?
Ribosomal proteins
Protein synthesis requires several components, several of which are constructed in the nucleus. Which is the only macromolecule involved that enters the nucleus, is modified, and then leaves via the nuclear pores?
Lysosome
The cells of a person with ALD swell with a build up of fatty acids. Which organelle is most likely failing to function correctly?
Eliminates excess water from the cytoplasm of freshwater protists
The contractile vacuole
40x
The eyepiece of a light microscope has a magnification level of 10x. If you were looking at a paramecium under the lowest-power objective (4x), what would be the total magnification of the microscope at this setting?
Chromatin
Under a light microscope which substance becomes visible as the cell divides?
Cristae
What are the inner folds of the mitochondria called?
