Answer

(a) Difference between Parenchyma and Collenchyma (cellular structure):

ParenchymaCollenchyma
Cell is large with thin cell walls having one large vacuole. Cells are oval, circular and polygonal.Elongated cells with thick cell walls. Cell walls thickened at corners.

(b) Difference between Meristematic and Permanent tissue (cell division):

Meristematic tissuePermanent tissue

(c) Difference between Blood and Lymph (cellular components):

BloodLymph
Blood consists of plasma, red blood cells, white blood cells and platelets.Lymph consists of plasma and white blood cells.

(d) Difference between Bone and Cartilage (porosity):

BoneCartilage
