Question:
After fertilization, the outer and inner integuments of an angiospermic ovule change into ________ respectively.
After fertilization, the outer and inner integuments of an angiospermic ovule change into ________ respectively.
Show Hint
The integuments form the seed coat: outer is testa and inner is tegmen.
Updated On: Nov 12, 2026
- seed and fruit
- testa and tegmen
- mesocarp and endocarp
- tegmen and testa
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
After fertilization the ovule develops into the seed. The integuments form the seed coat.
Step 2: Outer integument
The outer integument forms the thick, hard outer seed coat called the testa.
Step 3: Inner integument
The inner integument forms the thin inner seed coat called the tegmen.
Final Answer:
The outer and inner integuments become testa and tegmen respectively. \[ \boxed{\text{(B) }\text{testa and tegmen}} \]
