TL;DR: The endosperm is nuclear, cell wall initiation starts 5 days after pollination and A7-to 10-celled suspensor persists up to the dicot stage of the embryo, both integuments contribute towards formation of the seed coat.
Abstract: The endosperm is nuclear, cell wall initiation starts 5 days after pollination. During early stages endosperm nuclei exhibit synchrony in their division. Embryogeny is of the Asterad type. A7-to 10-celled suspensor persists up to the dicot stage of the embryo. Both integuments contribute towards formation of the seed coat. 30 days after pollination seeds become mature. Their endosperm is scanty and persists as a thin layer between the folds of the cotyledons. Nucellus remnants are present towards the funicular side.

TL;DR: Extracts of adult Paramphistomum explanatum have been shown to contain high concentration of acid phosphomonoesterase with maximum activity at pH 4.5 and an exhibition of an unexpected increase in the inhibitory action of a mercury at 1 mM concentration by EDTA.
Abstract: Extracts of adult Paramphistomum explanatum have been shown to contain high concentration of acid phosphomonoesterase with maximum activity at pH 4.5. The enzyme has been characterized by an exhibition of an unexpected increase in the inhibitory action of a mercury at 1 mM concentration by EDTA. With a lower concentration of mercury (0.1 mM and below) EDTA gave partial protection against inhibition. Different concentrations of magnesium and cobalt activated the enzyme while fluoride, copper, arsenate, tartrate and p-mercuribenzoate brought about inhibition. EDTA, glycine, glutathione and sodium azide had no effect. There was an indication of the presence of alkaline phosphomonoesterase at pH 10.0. The Km for p-nitrophenyl phosphate hydrolysis was 0.45 mM at pH 4.5.
