1
Q

plasmodesmata

A

cytoplasmic channels, lines cell walls enabling communication and transportation between cells that are stuck together

2
Q

extracellular matrix

A

provides support for cell and regulates internal communications

3
Q

tight junction

A

regulates water movement between epithelial layers, creates a tight bond between cells

4
Q

anchoring junction

A

hold cells together and provides tissue with structural cohesion. stabilize the cell position, provide stability and rigidity, and support tissue integrity by holding cell sheets together

5
Q

gap junction

A

using extracellular fluid, gap junctions allow for direct chemical communication

6
Q

tubulin

A

kills cancerous cells and is the building block for microtubules

7
Q

microtubule

A

to shape and support the cytoskeleton, aid in movement of cells, organelles, chromosomes (centrioles, cilia, flagella)

8
Q

centrosome

A

provides structure for a cell while working to pull chromatids apart during cell decision, anywhere centrioles are found

9
Q

centriole

A

active in cell division, formation of spindle fibers (no one really knows)

10
Q

microfilaments

A

maintains cell shape and helps it divides, made of actin, moves organelles and aids in endocytosis

11
Q

intermediate filaments

A

provide mechanical support for plasma membrane when it runs into other cells
