Question

4.7. describe the role of any given organelle in a eukaryotic cell. after the covid - 19 virus breaks through the plasma membrane, it encounters a network of protein cylinders and filaments collectively known as the cytoskeleton. the viruss genetic material travels to the endoplasmic reticulum (er), an extensive and interconnected network of sacs that are classified into two types: the smooth er where lipids and hormones are produced, and the rough er where some proteins are synthesized due to the presence of ribosomes embedded on the surface. complete the following passage. evidence suggests that viral particles form their external envelope at the er or the , where proteins and lipids are packaged and directed to their final destinations either inside or outside the cells. even when the virus replaces and leaves the cell, viral proteins still hijack the cell and can target the , a tiny power plant that fuels cellular activities. viral proteins also bombard the cells , the control center of the eukaryotic cell. during infection, viral proteins block the to prevent chemical messages from leaving the nucleus. in other words, the virus prevents the cell from sending a warning message to the immune system. chloroplasts golgi apparatus mitochondria lysosomes nucleus nucleolus cytoskeleton nuclear pores

Explanation:

1. The Golgi apparatus packages and directs proteins and lipids, so it's where viral particles may form their envelope.
2. Mitochondria are the power - plants of the cell, which viral proteins can target.
3. The nucleus is the control center of the eukaryotic cell.
4. Nuclear pores are used for the passage of chemical messages out of the nucleus, which viral proteins block.

Answer:

1. Golgi apparatus
2. mitochondria
3. nucleus
4. nuclear pores
