Open in App
Solution
The correct option is B 6 -10 celled
The function of suspensor is to anchor the embryo and push into nutritious endosperm. In general, zygote divides into two unequal cells, larger suspensor cell towards micropyle and a smaller embryonal cell towards antipodal region. One end of suspensor cells is at micropylar end and other becomes hypophysis.
The suspensor cell undergoes transverse divisions forming 6 to 10 celled long suspensor. The first cell of the suspensor is large and is called as haustorium or vesicular cell. The last cell of suspensor is known as hypophysis. It forms a radicle tip.
Thus, during embryogenesis in dicots, suspensor cells divide transversely to produce filamentous suspensor of 6-10 cells.
