MULTIPLE CHOICE
Directions: Each group of questions below consists of a numbered list of descriptive words or phrases accompanied by a diagram with certain parts indicated by letters or by a list of lettered headings. For each numbered word or phrase, select the lettered part or heading that matches it correctly and then insert the letter in the space to the right of the appropriate number. Sometimes more than one numbered word or phrase may be correctly matched to the same lettered part or heading.
1. ________ Haploid nuclei that fuse to form a zygote
a. Polar body
b. Capacitation
c. Acrosome
d. Zona pellucida
e. Pronuclei
ANS: E
The male and female pronuclei are the haploid nuclei of the sperm and oocyte, respectively. They fuse during fertilization to form the diploid nucleus of a zygote. The nucleus occupies most of the head of the sperm, and after it enters the oocyte, it swells to form the male pronucleus. The pronuclei are about equal in size and show similar features.
2. ________ Changes occur in it that inhibit entry of sperm
a. Polar body
b. Capacitation
c. Acrosome
d. Zona pellucida
e. Pronuclei
ANS: D
The zona pellucida undergoes changes, called the zona reaction, when a sperm contacts the cell membrane of a secondary oocyte. These changes, caused by the release of substances from the oocyte, prevent other sperms from passing through the zona pellucida and entering the oocyte.
