Which part of the cell is made up of a network of filaments that maintains the cell structure?
Cytoplasm
Endoplasmic reticulum
Cytoskeleton
Vacuoles
Cytoskeleton is basically
carbohydrate chains
lipids
Protein filaments
RNA
Which part of the cytoskeleton works with kinesin to move vesicles and organelles around the cell?
Actin Filaments
Intermediate Filaments
Microtubules
The Microtubules are important for:
Supporting the nuclear and plasma membranes
moving chromosomes
Moving the cell
The microfilaments are important for:
Supporting the nuclear and plasma membranes
Cell division
Moving the cell
The intermediate filaments are important for:
Supporting the nuclear and plasma membranes
Cell division
Moving the cell
Which is NOT a role of the cytoskeleton?
Maintain cell shape
Anchor organelles
Movement of the cell
Movement of molecules within a cell
Aides in Protein Synthesis
Which organelle is NOT composed in part by the cytoskeleton?
Cilia
Flagella
Vesicle
TRUE OR FALSE:
The microtubules of the cytoskeleton provide motor proteins bound to vesicles a track to travel along.
TRUE
FALSE
Cellular Junction in plant cells that allows small molecules in the cytoplasm to be shared between the cells to aide in communication.
Gap Junctions
Tight Junctions
Plasmodesmata
Desmosomes
Cellular Junction in animal cells that allows for cellular communication through flow of cytoplasm between cells.
Gap Junctions
Tight Junctions
Plasmodesmata
Desmosomes
Place a seal around the cells to prevent leakage.
Gap Junctions
Tight Junctions
Plasmodesmata
Desmosomes
Which type of cellular junction form a "quilted seal" between cells?
Tight junctions
Desmosomes
Gap Junctions
A type of inter-cellular connection in which the outermost portions of the two cell membranes have a tight seal together is termed a(n)
tight junction
intermediate junction
gap junction
desmosome
anchoring junctions
anchoring junctions
Plasmodesmata in plant cells are analogous to what structure in animal cells?
Tight junctions
Gap junctions
Adhesion junctions
Vacuoles
Urine is confined to the human bladder in part due to the structure of junctions that connect the cells lining the bladder. These junctions form a barrier that prevents the exchange of ions and solutes between the blood and urine. What is the likely identity of these junctions?
Gap junctions
Tight junctions
Anchoring junctions
Plasmodesmata
Which of these correctly matches the cellular junction with its function?
Gap junctions prevent the flow of ions and water from one part of the body to another
Anchoring junctions are branched network of proteins that are impermeable to fluids
Gap junctions are connections that directly connect the cytoplasm of two cells
Tight junctions are random, spot attachments between cells that prevent tearing of tissue
The endosymbiosis hypothesis proposes that
a large cell engulfed and digested a smaller cell, exposing its enzymes for use by the larger cell.
two cells merged into one cell, improving the enzyme function of the new cell.
two cells were juxtaposed and one benefited from the other.
a small cell lived inside a larger cell to the benefit of both cells.
