Explanation / Answer
1. Which of the following cell organelles are motile projections of the plasma membrane occurring in the large numbers in certain cells?
Answer- c. CILIA- Numerous, short, motile, hairlike projections which extend from the surface of a cell cause coordinated movements that cause the movement of fluid along the cell's surface.
2. Which of the following is a function of a group of plasma membrane proteins?
Answer- A. Cell-Cell recognition
3. When does DNA replication take place?
Answer- C. before a cell divides - mitosis is a part of cell cycle when replicated chromosomes are separated into two new nuclei. DNA is replicated before the cell divides i.e before mitosis.
4. Subcellular organelle that functions in detoxification of drugs and other toxic substance ______.
Answer- A. The smooth endoplasmic reticulum
5. What event typically begins in anaphase and is completed by the end of telophase?
