Vascular tissue which helps in movement of amino acids and sugars are
Select answers
A. Companion Cells
B. Sieve Tubes
C. Phloem Sclerenchyma
D. Xylem Vessels
Solution
The vascular tissue which helps in the movement of amino acids and sugars is Phloem. This is because Phloem is responsible for the transport of soluble organic material made during photosynthesis, known as photosynthates, from the leaves to other parts of the plant. This process is known as translocation.
The two main components of Phloem are Sieve Tubes and Companion Cells.
A. Companion Cells: These are parenchyma cells, located within the phloem of flowering plants. They help in the loading and unloading of sugars into the sieve tube elements.
B. Sieve Tubes: These are a series of cells joined end-to-end. They are responsible for transporting sugars and other nutrients throughout the plant.
C. Phloem Sclerenchyma: These are supporting cells in the Phloem.
D. Xylem Vessels: These are part of the xylem tissue, and they transport water and minerals from the roots to the leaves.
So, the correct answer is both A. Companion Cells and B. Sieve Tubes.
