Is large amount of extracellular matrix a characteristic of epithelial tissue?
No, epithelial tissue is primarily composed of closely packed cells with minimal extracellular matrix. The extracellular matrix is more abundant in connective tissue, which provides structural support and anchorage for epithelial cells.
An extracellular matrix is produced by glycoprotein secretion by what?
An extracellular matrix is produced by fibroblasts, which secrete glycoproteins such as collagen, elastin, and fibronectin. These glycoproteins form a network that provides structural support and biochemical cues for surrounding cells.
What r the natural surroundings of animal cell?
The natural surroundings of an animal cell include extracellular fluid, nutrients, oxygen, and neighboring cells, which provide support and communication. Additionally, animal cells may also interact with tissues, organs, and the extracellular matrix in their environment.
Does connective tissue contain extracellular matrix?
Yes, connective tissue contains extracellular matrix, which is a non-living material that provides structural support and connects cells within the tissue.
What are the two main components of all tissues?
The two main components of all tissues are cells (which are the basic structural and functional units) and the extracellular matrix (which is the material that surrounds and supports the cells). Together, cells and the extracellular matrix give tissues their structure and function.
What are cells often bound to the extracellular matrix by?
The cells are often bound to the extracellular matrix by proteins in the plasma membrane. The extracellular matrix is the structural support of tissue.
What attaches skin cells to the extracellular matrix by?
Plasmodesmata

The extracellular matrix is a coating found on the outside of .?
Animal Cells
What are the three main connections?
cells, fibers, and extracellular matrix. (:
Cells are often bound to the extracellular matrix by in the plasma membrane?
through proteins called integrins. Integrins act as molecular linkers between the extracellular matrix and the cell's internal cytoskeleton, allowing the cell to adhere to and interact with its surroundings. This interaction is vital for cell signaling, migration, and tissue organization.
An extracellular matrix is produced by glycoprotein secretion by what?
An extracellular matrix is produced by fibroblasts, which secrete glycoproteins such as collagen, elastin, and fibronectin. These glycoproteins form a network that provides structural support and biochemical cues for surrounding cells.
What gives strength to the cells?
Various factors contribute to cell strength, including the structural integrity of the cell membrane, the cytoskeleton providing support and shape, and the presence of cell adhesion molecules that allow cells to adhere to neighboring cells and the extracellular matrix. Additionally, the presence of osmotic pressure and turgor pressure can also play a role in maintaining cell shape and rigidity.
What type of membrane protein anchors cells to neighboring cells and to protein filaments found outside and inside the cell?
The type of membrane protein that anchors cells to neighboring cells and to protein filaments both outside and inside the cell is known as an integrin. Integrins are transmembrane proteins that facilitate cell adhesion to the extracellular matrix and other cells by binding to specific ligands. They play a crucial role in cellular signaling and maintaining tissue structure by connecting the cytoskeleton to the extracellular environment.
What tissue has a free surface and cells which are widely separated by extracellular matrix?
The tissue characterized by a free surface and cells that are widely separated by extracellular matrix is epithelial tissue. Epithelial tissue forms protective layers on body surfaces and lines cavities and organs, while the extracellular matrix provides structural and biochemical support. However, it is important to note that connective tissue also has widely separated cells and an extensive extracellular matrix, but it typically does not have a distinct free surface.
All what can be proteins found in the extracellular matrix of animal cells except?
Actin
What are extracellular cues?
Extracellular cues are signals or molecules that are present outside of cells and can influence their behavior. These cues can come from neighboring cells, the extracellular matrix, or other sources in the cellular environment to regulate processes like cell migration, growth, and differentiation.
