CONTENTS 3. The chromosomes in the cell nucleus would contain the most radioactivity because thymine is part of the DNA molecule and chromo-somes are composed of DNA. Inclusion/Special Needs Show students a picture of a bacterial cell and an animal cell. Talk about the location of DNA in each cell and where DNA replication occurs.

Be Part of Ask A Biologist It is the largest organelle in the cell and it contains the DNA of the cell. DNA (Deoxyribonucleic Acid) contains all the information for cells to live, perform their functions and reproduce. Inside the nucleus is another organelle called the nucleolus. The nucleolus is responsible for making ribosomes. The circles on the surface of the nucleus are the nuclear pores. These are where ribosomes, and other materials move in and out of the cell.

The Cell Nucleus The following cell structures can also be found in a typical animal eukaryotic cell: 1  Centrioles - help to organize the assembly of microtubules. 2  Chromosomes - house cellular DNA. 3  Cilia and Flagella - aid in cellular locomotion. 4  Cell Membrane - protects the integrity of the interior of the cell.

Organelle Structure and Function Membrane Bound Organelles. The Nucleus is the largest organelle in a cell. It contains a dense structure called the Nucleolus and is surrounded by the Nuclear Envelope, a structure composed of two membranes, seperated by fluid, which contain a number of nuclear pores that can allow relatively large molecules through.

- Under a light microscope the cell nucleus looks like a black dot and its size varies depending on the species and stage of the cell's life cycle. It is usually the largest organelle in the cell and can contain up to about 2 metres of DNA which has to be tightly coiled and packed so that it can fit in.

- The nucleus is one of the most important organelles in a cell. It is often the largest organelle in animal cells, but this is not always the case. Nuclei contain the genetic material called DNA that is responsible for controlling and directing all cell activities.ll eukaryotic cells have within them a variety of different structures called organelles. Organelles are small and function much like organs function in a large organism. Some organelles are responsible for gathering cell energy, others for controlling cell activities.

Eukaryotic Cells In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell's survival.n fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell's DNA is housed and the process of interpreting it begins. Recall that DNA contains the information required to build cellular proteins.

The Organelle That Controls the Cell's Activities & Contains DNA The parts of the nucleus reflect its functions. Most of the time, the entire nucleus is separated from the rest of the cell by a double-layered nuclear envelope. This membrane is covered with pores that regulate the movement of molecules in and out of the nucleus. Inside the nucleus, the nucleolus produces ribosomes, which make proteins for the cell.

Learn About Organelles There are also certain organelles found in plant cells that are not found in animal cells and vice versa. Examples of organelles found in plant cells and animal cells include: Prokaryotic cells have a structure that is less complex than eukaryotic cells.They do not have a nucleus or region where the DNA is bound by a membrane. Prokaryotic DNA is coiled up in a region of the cytoplasm called the nucleoid. Nucleus-a membrane bound structure that contains the cell's hereditary (DNA) information and controls the cell's growth and reproduction. 2  It is commonly the most prominent organelle in the cell. 3  Mitochondria-as the cell's power producers, mitochondria convert energy into forms that are usable by the cell.

It consist of nuclear pores that regulate the transportation of substances such as RNA into and out of the nucleus. The nuclear envelope consists of an outer nuclear membrane and an inner membrane.he nucleus is known as the information storage organelle. it is enclosed by a double membrane- nuclear envelope. Inside of the nucleus there is DNA. The DNA is bound by proteins- chromatin. The dark spot of the nucleus is the nucleolus-site or rRNA synthesis.

Cell Biology/Print version Nucleus [edit]. The nucleus contains genetic material or DNA in the form of chromatin, or, during mitosis or late interphase, chromosomes. All transcription and replication of genetic material takes place within the nucleus, as does mRNA processing.entral Vacuole The central vacuole is found only in plant cells. It is filled with water and is pressurised, like a balloon. This forces all the other organelles within the cell out toward the cell wall. This pressure is called turgor pressure and is what gives plants their crisp and firm structure.
