Question

Chalaza is
  1. Space between integument and nucellus
  2. Ridge formed by fusion of funicle with the body of ovule
  3. Place of origin of integuments
  4. Place where nucellus communicates with cavity of ovary

A
Space between integument and nucellus
B
Place where nucellus communicates with cavity of ovary
C
Ridge formed by fusion of funicle with the body of ovule
D
Place of origin of integuments
Solution
Verified by Toppr

• 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.
So, the correct answer is C.
