Blood is important in respiration in that it helps to transport oxygen and carbon dioxide.

Blood contains WBCs which protect our body from diseases and foreign bodies.

Parenchyma provides support to plants and also stores food. It is a basic packing tissue in plants. Parenchyma of stems and roots store water and nutrients. Sometimes it contains chlorophyll and performs photosynthesis ( called chlorenchyma) . In aquatic plants, parenchyma ( called aerenchyma) shows large air spaces to give buoyancy to plant.
