Parenchyma:
1. The cell wall is commonly thin but uniform in thickness.
2. It provides mechanical strength only when the cells are fully turgid.
3. Parenchyma is found in both the outer and inner parts of plant organs.
Collenchyma:
1. The cell walls develop extra thickenings at places (tangential walls, angles or adjacent to intercellular spaces).
2. Collenchyma is a living mechanical tissue.
3. Collenchyma is mostly restricted to the sub-epidermal parts of aerial plant organs.

Distance = Total length of the path.
He travelled one circular path. Hence distance is equal to circumference of circle.
∴ Distance = 2 π r
Displacement = Distance between initial and final position
He finally came to his initial position.
∴ Displacement = 0
