cytoskeleton and cell surfaces

Question 1

plasmodesmata

Answer 1

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

Question 2

extracellular matrix

Answer 2

provides support for cell and regulates internal communications

Question 3

tight junction

Answer 3

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

Question 4

anchoring junction

Answer 4

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

Question 5

gap junction

Answer 5

using extracellular fluid, gap junctions allow for direct chemical communication

Question 6

tubulin

Answer 6

kills cancerous cells and is the building block for microtubules

Question 7

microtubule

Answer 7

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

Question 8

centrosome

Answer 8

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

Question 9

centriole

Answer 9

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

Question 10

microfilaments

Answer 10

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

Question 11

intermediate filaments

Answer 11

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