Question

which is a structure that directs the cell’s activities?
○ nucleus
○ golgi apparatus
○ ribosome
○ mitochondrion

Explanation:

To determine the structure that directs a cell's activities, we analyze each option:

• Nucleus: Contains the cell's genetic material (DNA) and is responsible for controlling and directing all cellular activities, including growth, metabolism, and reproduction.
• Golgi apparatus: Modifies, sorts, and packages proteins and lipids for transport within the cell or secretion outside the cell. It does not direct overall cell activities.
• Ribosome: Involved in protein synthesis by translating mRNA into proteins. It is not the control center of the cell.
• Mitochondrion: Known as the "powerhouse" of the cell, it produces ATP (energy) through cellular respiration. It does not direct the cell's activities but provides energy for them.

Based on this analysis, the nucleus is the structure that directs the cell's activities.

Answer:

A. nucleus
