Answer 1

The correct option is B A-3, B-5, C-1, D-2, E-4

Cells vary greatly in size and shape.
Nerve cells are specialised cells that have long and branched nerve fibres.
Red blood cells (erythrocytes) are round and biconcave and have hemoglobin that helps to transport respiratory gases.
White blood cells (leucocytes) are amoeboid (looks like amoeba) in shape due to the presence of pseudopodia. The columnar epithelium is long and narrow shaped cells that are normally found in absorption and secretion regions.
Tracheids are elongated dead cells with highly lignified cell walls of plant cell.
