Question

plant cell wall structure
pectin
cross-linking glycan
cellulose microfibrils
middle lamella
primary cell wall
plasma membrane
figure 1
what other responsibilities do cell walls in plants have besides providing support?
duplicating the cellular dna
generating all cellular energy
communicating between tissues

Explanation:

• Analyze each option:
• "duplicating the cellular DNA" is done by cellular machinery like DNA polymerase, not the cell wall.
• "generating all cellular energy" is mainly by mitochondria (and chloroplasts for photosynthesis), not the cell wall.
• "communicating between tissues" is a function of the plant cell wall (e.g., through plasmodesmata - related signaling and structural connections for inter - tissue communication).

Answer:

C. communicating between tissues (assuming the third option is labeled C; if the original options had different labels, adjust accordingly. Based on the given options, the correct one is the option with "communicating between tissues")
