Answer: c
Clarification: Golgi bodies were named after the scientist who discovered them, Camillo Golgi. Golgi bodies contain flat, disc – shaped sacs called cisternae. The diameter of the cisternae is 0.5μm to 1.0μm.

10. The forming face of the Golgi complex is convex. True or false?
a) True
b) False
Answer: a
Clarification: The Golgi complex is made of sacs called cisternae. The forming face which faces the nucleus is convex or cis, while the maturing face which faces away from the nucleus is concave or trans.

11. Which of these is not a function of the Golgi apparatus?
a) Packaging of proteins
b) Modification of proteins
c) Synthesis of glycoproteins and glycolipids
d) Synthesis of proteins
Answer: d
Clarification: Golgi bodies are involved in the synthesis of glycoproteins and glycolipids. They are also involved in the modifications and packaging of proteins received from the endoplasmic reticulum. It does not synthesize proteins.

12. Which of these is not a lysosomal enzyme?
a) Lipases
b) Protease
c) Kinases
d) carbohydrase
Answer: c
Clarification: The lysosome contains various enzymes collectively known as lysosomal acid hydrolases. The enzymes are hydrolytic enzymes such as lipase, protease and carbohydrase. Kinases are not hydrolytic enzymes.

13. Which of these statements is false regarding lysosomes?
a) They are bound by a single membrane
b) They contain hydrolytic enzymes
c) Lysosomal enzymes are active at a basic pH
d) They can digest nucleic acids
Answer: c
Clarification: Lysosomes are bound by a single membrane. The contain hydrolytic enzymes which are active at an acidic pH and digest substances such as carbohydrates, proteins, lipids and nucleic acids, by hydrolysis.

14. What are the membranes of vacuoles called?
a) Tonoplast
b) Leucoplast
c) Amyloplast
d) Chromoplast
Answer: a
Clarification: Vacuoles are covered by a single membrane known as tonoplast. Vacuoles contain substances for storage such as water, or excretory products such as sap and other materials not useful for the cell.

15. Which of these is a function of the contractile vacuole in Amoeba?
a) Lipoprotein synthesis
b) Osmoregulation of the cell
c) Glycoprotein synthesis
d) Degradation of nucleic acids
Answer: b
Clarification: Vacuoles contain substances for storage such as water, or excretory products such as sap and other materials not useful for the cell. the contractile vacuole in Amoeba is responsible for osmoregulation and excretion.
