When male and female flowers are borne on different plants ,the plant is said to be.
A
Bisexual
B
Dioecious
C
Dichlamydeous
D
Monoceious
Explanation: 

Detailed explanation-1: -A dioecious plant is one where the male and female reproductive systems occur on separate plants. While both plants produce flowers, one plant has the male reproductive parts and the other plant has the female parts. This is unlike a monoecious plant, which has both male and female flowers.

Detailed explanation-2: -In dioecious plants, the male and female flowers are borne on separate individuals (male and female plants). These plants constitute only 4% of flowering plant species. Sorrel (Rumex acefosa; Polygonaceae) is one of only 13 plant species in which dioecy is determined by identifiable sex chromosomes (Parker, 1990).

Detailed explanation-3: -Dioecious plants house the male and female flowers on different plants. So not only does the plant have separate male/female flowers, they have male plants (with only male flowers) and female plants (with only female flowers). Hollies and asparagus are dioecious.

Detailed explanation-4: -Monoecious” is translated as “single house, ” meaning that male and female flowers are found on a single individual. This contrasts with the translation of dioecious, which is “double house.” This means that male flowers are on one plant and female flowers are on another plant.

Detailed explanation-5: -In monoecious plant, both male and female flowers are borne on the same plant. Maize is a monoecious plant, which means it has both male and female flowers at various places on the same plant.
