Explain the process of development of monocot embryos.

The zygote or oospore elongates and then divides transversely to form basal and transversely to form basal and terminal cells. The basal cell (towards the micropylar end) produces a large swollen, vesicular suspensor cell. It may function as haustorium. The terminal cell divides by another transverse wall to form two cells. The top cell after series of divisions forms plumule and single cotyledon. Cotyledon called scutellum grows rapidly and pushes the terminal plumule one side. The plumule comes to lie in a depression. The middle cell, after many divisions, forms hypocotyl and radicle. It also adds a few cells to the suspensor. In some cereals both plumule and radicle get covered by sheaths developed from scutellum called coleoptile and coleorhiza respectively.
