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
Adhering 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
Adhering 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.
