Question

In dicot embryo hypophysis is

• A. Terminal cell of suspensor that takes part in absorption of nourishment
• B. Middle cell of suspensor that grows to push the embryo downwards
• C. Last cell of suspensor that forms radicle
• D. Part of embryo that gives rise to radicle

Answer 1

Answer: (A)

Terminal cell of suspensor that takes part in absorption of nourishment

After fertilisation of the egg, a zygote is formed. The zygote divides by mitosis to form two cells, a smaller daughter cell towards the chalazal pole, called the apical cell and a larger daughter cell towards the micropylar pole called the basal cell. The basal cell divides several times transversely to form a row of cells which is called the suspensor. The lowermost i.e terminal cell of the suspensor functions as hypophysis which helps in nutrient absorption.

So, the correct answer is A.
