five unit: “the cell and the smallest living being”
... -A cell is the smallest part of a living being. We need a microscope to see it. The size of cells is measured by a micrometer. -There are some cells without a nucleus. They are prokaryotic cells. These are bacteria cells. The rest of the cells are eukaryotic, and they have a nucleus. -Animal cells a ...

Cell Division
... The cells in a human infant are the same size as the cells in an adult. Why? 1. If a cell were to get bigger as an organism grows, eventually the cell membrane would not be able to handle the transport of materials into and out of the cell. 2. The cell would need too many raw materials and would mak ...

Extracellular matrix
In biology, the extracellular matrix (ECM) is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells. Because multicellularity evolved independently in different multicellular lineages, the composition of ECM varies between multicellular structures; however, cell adhesion, cell-to-cell communication and differentiation are common functions of the ECM.The animal extracellular matrix includes the interstitial matrix and the basement membrane. Interstitial matrix is present between various animal cells (i.e., in the intercellular spaces). Gels of polysaccharides and fibrous proteins fill the interstitial space and act as a compression buffer against the stress placed on the ECM. Basement membranes are sheet-like depositions of ECM on which various epithelial cells rest.The plant ECM includes cell wall components, like cellulose, in addition to more complex signaling molecules. Some single-celled organisms adopt multicelluar biofilms in which the cells are embedded in an ECM composed primarily of extracellular polymeric substances (EPS).
