C Place of origin of integuments
• The ridge formed by the fusion of funicle with the body of ovule is called Raphe.
• The space between integument and nucellus is called endostome.
• Integuments originate from the base of chalaza and terminate towards the micropyle where they cover the minute opening called micropyle.
• Place where the Nucellus communicates with the cavity of ovary is the Placenta.
Hence, chalaza is the place of origin of integuments.
