Ovule with fimiculus lying close to micropyle is known as:

A)  anatropous    

B)  campylotropous

C)  atropous      

D)  cytokinin

Correct Answer: A

Solution :

 Anatropous is the inverted ovule, with funiculus (stalk) lying close to micropyle (narrow pore or passage at one end of the ovule). Atropous or orthotropous is the erect ovule with the micropyle opposite to the chalaza (place of origin of integuments) here the funicle, micropyle and chalaza lie in a straight line. Campylotropous ovule is curved and bent so as to bring the hilum (point of attachment of the body of the ovule with the funiculus), micropyle and chalaza close together. Cyfokinin is a plant growth hormone that promotes cell division.
