![]() ![]() Some substances like carbon dioxide or oxygen can move across the cell membrane by a process called diffusion.Plasma membrane is a selectively permeable membrane.Amoeba acquires its food through such processes. Such processes are known as endocytosis (endo → internal cyto → of a cell). The flexibility of the cell membrane also enables the cell to engulf in food and other material from its external environment.The plasma membrane is flexible and is made up of organic molecules called lipids and proteins. ![]() Plasma membrane is the outermost covering of the cell that separates the contents of the cell from its external environment.It can be observed only through an electron microscope.Cell membrane is also called the plasma membrane.With the discovery of the electron microscope in 1940, it was possible to observe and understand the complex structure of the cell and its various organelles.Presented The cell theory, that all the plants and animals are composed of cells and that the cell is the basic unit of life. In addition, we have included books in Spanish and Portuguese, so that you have the opportunity to read books on Cell Biology in these languages.įinally, we consider it important to point out that these publications have been made available for free distribution, or belong to the public domain.Discovered and coined the term cell in 1665 Cellular processes of development, among many others.Adhesions and junctions between the extracellular matrix and cells.The origin of this discipline is to be found in two different disciplines: histology and cytology.Ĭell Biology also studies the organisms that are housed in cells such as viruses, proviruses, bacteria, among others which possess DNA from current infections and those of our ancestors, collaborating with the development of cures for diseases.Īmong the topics covered by Cell Biology we can mention the following: The concept of Cell Biology is more or less modern, and is defined as the study of the life of cells. With the idea of allowing you to have easy and free access to this compendium of publications, we have chosen all of them in PDF format. A selection of free books on a subject as important and enlightening as Cell Biology, is the gift that we want to give you today. ![]()
