Question

Two adjacent vessels and tracheids exchange sap through

• A. Perforated end walls
• B. Pits
• C. Intercellular spaces
• D. Intercellular spaces and parenchyma

Answer 1

The correct option is B Pits

Pits are thin portions of the cell wall that adjacent cells can communicate or exchange fluid through. Pits are characteristic of cell walls with secondary layers. Generally each pit has a complementary pit opposite of it in the neighboring cell. These complementary pits are called "pit pairs". Pit pairs are a characteristic feature of the xylem, as sap flows through the pits of xylem cells.

So, the correct answer is 'Pits.'
