Question

correctly match the terms and definitions from this chapter below.
a protective layer external to the plasma membrane in the cells of plants. the polysaccharide cellulose creates the cell wall structure. choose
the meshwork surrounding animal cells, consisting of glycoproteins, polysaccharides, and proteoglycans synthesized and secreted by cells. choose
an open channel through the cell wall that connects the cytoplasm of adjacent plant cells, allowing water, small solutes, and some larger molecules to pass between the cells. choose
a type of intercellular junction in animal cells, consisting of proteins surrounding a pore that allows the passage of materials between cells. choose
a type of intercellular junction between animal cells that prevents the leakage of material through the space between cells. choose

Explanation:

To solve this, we match each definition to the correct term (common terms in cell biology for these definitions are: Cell Wall, Extracellular Matrix, Plasmodesmata, Gap Junction, Tight Junction).

1. First Definition:

"A protective layer external to the plasma membrane in the cells of plants. The polysaccharide cellulose creates the cell wall structure."
This matches Cell Wall (defines plant cell wall with cellulose).

2. Second Definition:

"The meshwork surrounding animal cells, consisting of glycoproteins, polysaccharides, and proteoglycans synthesized and secreted by cells."
This matches Extracellular Matrix (describes the ECM around animal cells).

3. Third Definition:

"An open channel through the cell wall that connects the cytoplasm of adjacent plant cells, allowing water, small solutes, and some larger molecules to pass between the cells."
This matches Plasmodesmata (plant cell junctions for intercellular transport).

4. Fourth Definition:

"A type of intercellular junction in animal cells, consisting of proteins surrounding a pore that allows the passage of materials between cells."
This matches Gap Junction (animal cell junctions with pores for material exchange).

5. Fifth Definition:

"A type of intercellular junction between animal cells that prevents the leakage of material through the space between cells."
This matches Tight Junction (animal cell junctions that seal intercellular spaces).

Final Matches (assuming the dropdowns accept these terms):

1. Cell Wall
2. Extracellular Matrix
3. Plasmodesmata
4. Gap Junction
5. Tight Junction

(Note: If the dropdowns have these terms, select them accordingly. The key is recognizing the cell biology concepts for each definition.)
