Nucleus Contains __ DNA Controls the __ of the cell. Nuclear Membrane Controls movement of __ in/out of the __ Ribosome Builds __ Vesicle A __ -bound container that __ materials around the cell. __ vesicles and __ are examples. Pouah Endoplasmic Reticulum (ER)

## Step 1<br />The nucleus is the control center of the cell. It contains DNA, which is the genetic material that carries the instructions for the development, functioning, and reproduction of all living organisms. The DNA in the nucleus controls the activities of the cell.<br /><br />##2<br />The nuclear membrane, also known as the nuclear envelope, is a double membrane that encloses the nucleus. It controls the movement of substances in and out of the nucleus.<br /><br />## Step 3<br />Ribosomes are the sites of protein synthesis in the cell. They build proteins by translating the genetic information carried by mRNA Step 4<br />Vesicles are small, membrane-bound containers that transport materials around the cell. They can carry various substances, including proteins, lipids, and other cellular components.<br /><br />## Step 5<br />The Rough Endoplasmic Reticulum (ER) is a type of organelle in the cell that is involved in protein synthesis and processing. It is called "rough" because it has ribosomes attached to its surface, which give it a bumpy appearance under a microscope.
