Eucaryotic Cell Structure and Function

True or False Quiz


1	Eucaryotic cells differ most obviously from procaryotic cells in having complex membranous organelles in the cytoplasmic matrix and most of their genetic material in a membrane-delimited nucleus.
		A)	True
		B)	False


2	In eucaryotes, genetic material is distributed between cells by the highly organized, complex processes called mitosis and meiosis.
		A)	True
		B)	False


3	Despite great morphological difference between eucaryotic cells and prokaryotes, they are remarkably similar metabolically.
		A)	True
		B)	False


4	The endosymbiotic theory states that eucaryotic organelles such as mitochondria and chloroplasts arose when bacteria established a symbiotic relationship with the eucaryotic ancestor and then evolved into organelles.
		A)	True
		B)	False


5	In contrast to procaryotes, many eucaryotic microorganisms do not have a cell wall. When they do, the walls of eucaryotic cells are generally constructed of polysaccharides and are simpler than that of procaryotic cells.
		A)	True
		B)	False


6	Cilia and flagella are the most prominent structures that enable eucaryotic cells to move.
		A)	True
		B)	False


7	Cell walls, rather cytoskeletons, give eucaryotic cells their shape.
		A)	True
		B)	False


8	Some examples of eucaryotic organisms are algae, fungi, protozoa and actinomycetes.
		A)	True
		B)	False


9	An advantage of eucaryotic organellar organization is that it can easily overcome physical limitations on the diffusion of nutrients and waste products.
		A)	True
		B)	False


10	The 80S ribosomes of eucaryotes are made up of 50S and 30S subunits.
		A)	True
		B)	False


11	One of the main differences between eucaryotic and procaryotic plasma membranes is that eucaryotic plasma membranes contain a sterol such as cholesterol.
		A)	True
		B)	False


12	The rough part of rough endoplasmic reticulum (RER) is caused by bound ribosomes in the process of synthesizing ER proteins.
		A)	True
		B)	False


13	The nucleolus is where the structural RNA for the cells ribosomes is transcribed from DNA.
		A)	True
		B)	False
