Question

Write a brief account of the structure of the ovule of angiosperms.

Answer 1

• A mature ovule of angiosperms is almost oval and has the following parts.
• The body of the ovule is called the nucellus.
• It remains covered by two integuments. 
• These arise from the base of the ovule. 
• At the free end of the ovule, the integuments are incomplete and so there is a minute opening called micropyle. 
• The stalk of the ovule is called as funicle. 
• The point of attachment of the body of an ovule with the stalk is called hilum. 
• The base of the ovule from where integuments arise is called chalaza
