2. Nucleus (Directs cell Activity)
You can think of the nucleus as the cell’s control center, directing all of the cell’s activities. This structure, called the nucleus (noo klee us), acts as the “brain” of the cell.
You can think of the nucleus as the cell’s control center, directing all of the cell’s activities. You might wonder how the nucleus “knows” how to direct the cell. The answer lies in those thin strands floating directly ahead in the nucleus. These strands, called chromatin, contain genetic material, the instructions for directing the cell’s functions. For example, the instructions in the chromatin ensure that leaf cells grow and divide to form more leaf cells. Nucleolus: This structure, a nucleolus, is where ribosomes are made. Ribosomes are the organelles where proteins are produced.
