The nucleus, nucleolus, and ribosomes

[go to this section in the Guide]
Chapter Three: Cell Structures


Question 1
 The nucleus is sometimes called the cell's "brain" because it
   1.  is the center of a system of nerves in the cell
2.  houses the cell's DNA which controls protein production
3.  instantly makes decisions for the cell
4.  directly synthesizes other organelles
 

Question 2
 The nucleus is surrounded by
   1.  a large vacuole
2.  the nuclear membrane
3.  the endoplasmic reticulum
4.  the nucleolus
 

Question 3
 The function of the nucleolus is to
   1.  physically contain the nucleus
2.  destroy poisons threatening the nucleus
3.  synthesize DNA
4.  produce ribosomes
 

Question 4
 The main function of ribosomes is to
   1.  neutralize poisons
2.  produce DNA
3.  destroy old organelles
4.  synthesize proteins
 

Question 5
 Ribosomes consist of
   1.  protein and ribosomal RNA
2.  polysaccharides and ribosomal DNA
3.  pectins and ribosomal sugars
4.  peptidoglycans and ribosomal lipids
 

Question 6
 The two main places where ribosomes are located are
   1.  the Golgi bodies and the nucleus
2.  lysosomes and peroxisomes
3.  the endoplasmic reticulum and the cytoplasm
4.  vacuoles and the mitochondria
