Biology Cell Parts

Nucleus - cell "brain" or control center. The nucleus is the membrane structure of the cell and plays two important roles in controlling the cell. The nucleus carries the genetic information of the cell and determines whether the organism grows, for example, into trees or humans, which dominates most cellular activities, including growth, metabolism, and breeding, by controlling protein synthesis. The presence of nuclei distinguishes more complex eukaryotic cells from plants and animals from simpler prokaryotic cells lacking nucleated bacteria and cyanobacteria.

Curiosity, if nothing else, should drive us to study cell biology; we need to understand cell biology to understand ourselves. But there are practical reasons that cell biology should be part of the education of all. We are made of cells, we are eating the cells. And our world is made of cells. The challenge for scientists is to deepen our understanding of cells and find new ways to apply them. As citizens, we all need to understand the themes related to the modern world, from our own health problems to environmental change, biomedical technology, agriculture, and epidemic diseases.

Cell biology is a biological science field that studies cell structure, physiology, growth, reproductive, and death. In cell biology research we use microscopes and molecular tools to examine all kinds of cells, from unicellular organisms such as protozoa to specialized cells that make up multicellular organisms.

Cell biology (also known as "cellology" from the Greek κύτος, kytos) is a field of biology that studies the structure and function of cells, the basic unit of life. Cell biology involves the physiological properties of cells and their environment, metabolic processes, signaling pathways, life cycles, chemical composition and interactions. Since it contains prokaryotic and eukaryotic cells, it is done at the microscopic and molecular levels. Understanding how cellular components and cells work is the foundation of all biological sciences and important for research in biomedical fields such as cancer and other diseases. Cell biology research is closely related to genetics, biochemistry, molecular biology, immunology and cytochemistry
