Biology Question on sexual reproduction in flowering plants
Apomictic embryos in Citrus arise from
A
synergids
B
maternal sporophytic tissue in ovule
C
antipodal cells
D
diploid egg.
Answer
maternal sporophytic tissue in ovule
Explanation
Solution
Apomixis is abnormal kind of sexual reproduction in which egg or other cells associated with egg (synergids, antipodals, etc.) develop into embryo without fertilization and meiosis. Development of embryos directly from sporophytic tissues like nucellus and integuments is called adventive embryony which is also a type of apoximis. E.g., Citrus, mango.
