Answer 2

Answer:

The correct answer is A. sieve plates.

Explanation:

• The living tissue known as phloem is responsible for carrying organic materials to all areas of plants.
• Conducting cells, parenchyma cells, and supporting cells are the three types of cells that make up phloem.
• Sieve tubes, a conducting cell in the phloem, are important in the movement of sugar to various sections of plants. One sort of parenchyma cell is the companion cell.
• Since companion cells perform every function of sieve tubes, the sieve tube's operation is dependent on them.
• Through their cytoplasm, companion cells are linked to the sieve tube. In between they are plasmodesmata.
