: having or being a plant ovule inverted so that the micropyle is bent down to the funiculus to which the body of the ovule is united.

What is Hemitropous?

hemitropous (comparative more hemitropous, superlative most hemitropous) Turned half round; half inverted. (botany, of an ovule) Having the raphe terminating about halfway between the chalaza and the orifice; amphitropous.

In which plant Circinotropous ovule is found?

Opuntia- Option a: Opuntia has a Circinotropous ovule. In this type of ovule, the length of the funiculus increases and covers the whole ovule. Therefore, this option is correct. – Option b: Ranunculus has a hemi anatropous ovule in which the body of the ovule is turned through 90°.
