The function of a nucleus is that it controls nearly all the activities that is taken place in the body. The function of the nucleus is to help control all the activities inside the cell. Also the nucleus controls the cells growth and reproduction. Chromosomes Chromosomes are long threads of DNA and protein seen in a dividing cell. They contain the genetic material or genes.

There are many parts of a cell, they all have specific duties, and are all

The nucleus is like the brain of the cell.The other reason why nucleus is called the control center is that- It has genetic material called DNA which undergo different functions such as replication, transcription, translation i.e. formation of different enzymes and proteins necessary for the development of whole cell Another reason is that-the cell which lac nucleus during abnormal cell division known to be dead cell.

Essentially, the nucleus is vital for the cell’s survival. The nucleus controls and gives instructions to all organelles and inhabitants of the cell(Doc. 2). It is a dense, ball shaped configuration that contains the DNA of the cell.

One of the main manufacturing facilities within a cell. Consists of rough ER and smooth ER, they are physically connected but differ in structure. Consist of membrane-enclosed tubes and sacs within the cytoplasm. Rough ER, named for the ribosomes attached to its surface, make membrane and secretory proteins. One function of rough ER is to produce new membrane. Some products by rough ER are dispatched to other locations by transport vesicles.

Nucleus – The nucleus is the largest organelle in the cell. It acts as the control system for almost all the activities of the cell. It stores the cell 's hereditary material, or DNA

The cell’s nonmembranous organelles include the cytoskeleton, microvilli, centrioles, cilia, ribosomes, and proteasomes. Membranous organelles include the endoplasmic reticulum, the Golgi apparatus, lysosomes, peroxisomes, and mitochondria.

There are two main types of cells in the world. The simplest cells such as bacteria are known as Prokaryotic cells, and human cells are known as Eukaryotic cells. The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life.

The nucleus is the control centre of a cell. It contains genetic material such as DNA and controls the cell's growth and

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

The cytoplasm is the area between the nucleus and the cell membrane. The cytoplasm contains many important structures. This area is basically the main place where you will find structures that help the cells stay alive.

The cell is the smallest unit able to sustain life, and they are often referred to as the building blocks of life. There are two primary types of cell, which are categorized according to the way their genetic material is packaged, rather than size or shape. These are:

Nucleus- “the brain” or control center of the cell. The Nucleus, a membrane-bound structure of a cell, plays two crucial roles in controlling the cell. The nucleus carries the cell's genetic information that determines if the organism will develop, for instance, into a tree or a human; and it directs most cell activities including growth, metabolism, and reproduction by controlling protein synthesis. The presence of a nucleus distinguishes the more complex eukaryotic cells of plants and animals from the simpler prokaryotic cells of bacteria and cyanobacteria that lack a nucleus. The nucleus is the most predominate structure in the cell. It is typically round and occupies 10% of the cells total volume. The nucleus is wrapped in a

The cytoplasm is a semifluid in the plasma membrane. It is in all eukaryotic cells. In prokaryotes, this is where the chemical processes of the cell take place. In eukaryotic cells, this is where organelles perform their functions. Cellular respiration also takes place here. One of stages of cellular respiration is glycolysis. Glycolysis is when glucose breaks down to form two pyruvates and 4 ATP. Its net result of 2 ATP is important for another process called the Krebs Cycle. This process is important because it begins cellular respiration. The cytoplasm also gives the cell its shape; without it, the cell would be “deflated” and substances would not be able to move throughout the cell. Organelles would have difficulty functioning too. It has been misunderstood that organelles float freely in the cytoplasm even
