Answer 2

Answer:1)Parenchyma is one of the types of living plant cells originating from ground and protoderm meristem. ... Whereas collenchyma cells have an uneven cell wall made up of pectin and hemicellulose. There is a hard and thick cell wall present of the sclerenchyma cells, which is made up of the lignin

2)Red blood cells (RBC, erythrocytes) are hemoglobin-carrying cells that primarily transport oxygen. White blood cells (WBC, leukocytes) take the form of either granulocytes or lymphocytes. Granulocytes are part of the innate immune system and play a key role in the immune response to bacteria, fungi, and parasites.
