What is the living layer around cells?
The living layer around cells is called the extracellular matrix (ECM). It is a complex network of proteins, glycoproteins, and polysaccharides that provides structural support and biochemical cues for cells. The ECM plays a crucial role in cell adhesion, migration, and signaling.
What is the red material between the cells?
The red material between the cells is likely referring to the extracellular matrix (ECM), a complex network of proteins and carbohydrates that provides structural and biochemical support to surrounding cells. The ECM plays a crucial role in tissue formation, cell signaling, and facilitating communication between cells. In some contexts, the red color could also be attributed to the presence of specific proteins or dyes used in microscopy to highlight certain components.
What is a sticky coat secreted by most animal cells?
The sticky coat secreted by most animal cells is called extracellular matrix (ECM). It is composed of proteins and carbohydrates and provides structural support, adhesion, and signaling to surrounding cells. The ECM plays a crucial role in cell migration, tissue development, and maintenance of tissue integrity.
Where is the extracellular coating found?
The extracellular coating, often referred to as the extracellular matrix (ECM), is found outside the cells within tissues in multicellular organisms. It provides structural and biochemical support to surrounding cells and is composed of proteins, glycoproteins, and polysaccharides. The ECM plays a crucial role in tissue and organ formation, as well as in cell signaling and communication. It is particularly abundant in connective tissues, such as cartilage, bone, and fibrous tissues.
Immature cells that actively divide by mitosis and create most of the ECM of cartilage are?
Immature cells that actively divide by mitosis and create most of the extracellular matrix (ECM) of cartilage are known as chondroblasts. These cells are responsible for producing the components of the cartilage matrix, including collagen and proteoglycans. As they continue to secrete the ECM, they eventually become encased in it and differentiate into chondrocytes, which maintain the cartilage tissue.
What holds the cells together?
Cells are held together by specialized structures called cell junctions, which include tight junctions, gap junctions, and desmosomes. These junctions provide adhesion and communication between neighboring cells, allowing them to function as a cohesive unit within tissues and organs.

what is unit structure of a tissue?
The unit structure of a tissue is called a functional tissue unit (FTU). An FTU is a group of cells that are close together and are connected to each other by a network of extracellular matrix (ECM). The ECM is a complex of proteins and other molecules that provides support and structure to the cells. The cells in an FTU work together to perform a specific function.
What fills the space between cells?
Extracellular matrix (ECM) fills the space between cells. It is a complex network of proteins and carbohydrates that provides structural support to cells and regulates various cellular functions. The ECM also plays a crucial role in cell signaling and tissue development.
Abundant nonliving extracellular matrix?
The extracellular matrix (ECM) is a complex network of proteins and carbohydrates that provide structural support for cells in tissues. It is abundant in tissues with high mechanical stress, such as cartilage, tendons, and bone. The ECM also plays a role in cell signaling, tissue development, and wound healing.
What does the ecm look like?
The ECM, or extracellular matrix, is a complex network of proteins and carbohydrates that provides structural and biochemical support to surrounding cells. It typically consists of collagen, elastin, fibronectin, and various glycoproteins and proteoglycans. The ECM can vary in appearance depending on the tissue type, but it generally forms a gel-like or fibrous scaffold that influences cell behavior, differentiation, and communication. Its organization and composition are crucial for tissue integrity and function.
What provides structure for tissues and organs and help carry out cell metabolism?
The extracellular matrix (ECM) provides structure to tissues and organs. It consists of proteins like collagen and fibronectin that give tissues their shape and mechanical strength. Cells interact with the ECM to carry out processes like cell metabolism, growth, and signaling.
Do adjacent cells share a common sheath?
Yes, adjacent cells can share a common sheath called the extracellular matrix (ECM) that provides structural support and communication between cells. The ECM is composed of proteins, glycoproteins, and polysaccharides that help cells adhere to each other and the surrounding tissue.
What is a major difference in the extracellular matrix ECM between plant and animal cells?
1) Plant cells have a cell wall as well as a cell membrane, animal cells only have a cell membrane 2) Plant cells have chloroplasts as well as mitochondria, while animal cells only have mitochondria 3) Plant cells tend to be more rectangular shaped and animal cells tend to be more round shaped. 4) Plant cells store glucose in the form of of starch granules and cellulose, animal cells store glucose in the form of glycogen.
Skin cells are attached to the extracellular matrix by?
Many cells bind to components of the extracellular matrix. This cell-to-ECM adhesion is regulated by specific cell surfacecellular adhesion molecules (CAM) known as integrins. Integrins are cell surface proteins that bind cells to ECM structures, such as fibronectin and laminin, and also to integrin proteins on the surface of other cells. Fibronectins bind to ECM macromolecules and facilitate their binding to transmembrane integrins. The attachment of fibronectin to the extracellular domain initiates intracellular signaling pathways as well as association with the cellular cytoskeleton via a set of adaptor molecules such as actin.[2]
