Cells are the basic units of all living organisms. Most cells contain a nucleus, which houses all of that organism's genetic material. Most cells also contain organelles, which are tiny membrane-bound structures in the cell's cytoplasm which carry out specific tasks and functions. Animal cells ...
This lesson will teach you about different cells in the human body. You will learn about four of the main type of cells that help the human body perform important functions. What Are Cells? Take a look at your hand. You may notice that it is covered in skin, or that you need to...
Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is characterized by specific functions that contribute to the overall health and maintenance of the body. A di...
The mechanisms which generate differences between cell types have been a major problem in biology. Every tissue in a eukaryote is made up of a mixture of cell types. The intrinsic molecular properties of these cell types and the interaction between cells gives rise to the specialized functions ...
A crucial question in mammalian development is how cells of the early embryo differentiate into distinct cell types. The first decision is taken when cells undertake waves of asymmetric division that generate one daughter on the inside and one on the outside of the embryo. After this division, ...

Types of Cells Plant and Animal Cells Differences in Plant and Animal Cells Summary Frequently Asked Questions What are the differences between plant cells and animal cells? There are several differences between plant and animal cells. Plant cells contain chloroplasts, a central vacuole, and a cell...
Binary fission is the type of cell division that takes place in prokaryotes (bacteria and archaea). Genetic material (nucleoid) in these cells is arranged in a single circular chromosome of the DNA. In a similar fashion to eukaryotes, the genetic material of these cells is duplicated before ...
discuss the regulatory signaling that controls their individual and collective functions. Most of these observations stem from the study of carcinomas, in which the neoplastic epithelial cells constitute a comp 我们这里列举一套知道的细胞类型贡献用重要方式对许多肿瘤生物和谈论控制他们各自和集体作用的管理...
The Human Cell Atlas (HCA) is an international group of researchers using a combination of these new technologies to create cellular reference maps. The HCA use CL to annotated cells in their reference maps. Regev,A., Teichmann,S.A., Lander,E.S., Amit,I., Benoist,C., Birney,E., Bode...
