Which of the statements regarding plasmodesmata is true? They are channels, located in the plasma membrane of plant cells and made of transmembrane proteins, that allow ions and small molecules to pass between adjacent cells. They are holes in the cell wall through which the plasma membrane and endoplasmic reticulum of adjacent cells are connected. They are channels, located in the plasma membrane of animal cells and made of transmembrane proteins, that allow ions and small molecules to pass between adjacent cells. They provide points of structural support between adjacent plant cells. They provide points of structural support between adjacent animal cells.

The difference between a gap junction and plasmodesmata is… Select one: a. Gap junctions are formed by microfilaments while plasmodesmata are formed by membrane b. Gap junctions are anchoring junctions while plasmodesmata are protein junctions. c. Gap junctions are formed by proteins making pores between two animal cells while plasmodesmata are formed due to incomplete cell division of membranes from adjoining plant cells.
The gap junctions of animal cells differ from the plasmodesmata ofplant cells in thata. gap junctions serve as communicating junctions and plasmodesmataserve as anchoring junctions.b. gap junctions prevent extracellular material from moving betweenadjacent cells but plasmodesmata do not.c. gap junctions allow for direct exchange of cellular material betweencells but plasmodesmata cannot allow the same type of exchange.d. gap junctions are formed by specialized proteins that form channelsthrough the membranes of adjacent cells but plasmodesmata areformed by connecting the plasma membranes of adjacent cells.e. All of the above are correct.
Which of the following statements about plasmodesmata is true? a. They prevent cytoplasm from passing between cells. b. They are important in the formation of tight junctions. c. They may float freely in the cytoplasm or be membrane-bound. d. They allow adjacent plant cells to communicate with each other.
Which one of the following structures between two adjacent cells is an effective transport pathway? A Plasmalemma B Plasmodesmata C Plastoquinones D Endoplasmic reticulum
You are studying how a newly discovered virus in bats enters their cells. When you examine cells that have taken up the virus, you find virus particles inside clathrin-coated vesicles. What membrane transport mechanismis the virus using to get inside the bat cells? Diatoms are protists that have complex glassy structures in their cell walls. These structures form within the Golgi apparatus. How do these structures reach the cell wall without having to pass through the plasma membrane?
