Odd man out
Onion, Cycas, Thuja, Deodar​

Answer 1

Among these Onion is odd one out.

• Because onion is an angiosperm ; that is it consists of flower and produces seeds which are enclosed in carpel.
• Angiosperms have adventitious root and seeds have single cotyledon.
• While other three are gymnosperms ; that is here the seeds are not covered or unprotected by the fruit.
• Angiosperm seeds are dicotyledonous and have tap root system.
