Answer 2

Answer:

Mesophyll tissue of the PInus needle is composed of A) Armed parenchyma.

Explanation:

• The presence of armed mesophyll cells is a distinct feature of the pinus needles.
• It is called so because the cell walls are folded inwards or invaginated into the lumen, which gives the cells a distinct lobed shape with arms.
• These are also considered to be star-shaped parenchymatous cells.
• The presence of armed parenchyma in the mesophyll tissue of the Pinus needle is a distinctive feature of the plant.
• The invaginations have various functions- increase the surface area of the mesophyll, and provide mechanical strength; leaf aeration may be increased due to this.
