Monoecious vs. Dioecious
The main difference between the monoecious and the dioecious is that Monoecious organisms have both female and male reproductive organs present in the same individual, whereas Dioecious organisms have male and female organs in separate individuals.
Key Differences
The word “Monoecious” literally means “one house” on the other hand, the word “Dioecious” literally means “two houses.”
Monoecious are bisexual; conversely, dioecious are unisexual, i.e., either male or female.
In monoecious plants, both female and male flowers exist on the same plant on the flip side. In dioecious plants, female and male flowers are present on separate plants.
Monoecious plants can easily reproduce, even in isolation. On the other hand, dioecious plants cannot reproduce in isolation.
In monoecious plants, both male and female gametes are produced on the same plant while, in dioecious plants, male and female gametes are produced on separate plants.
Monoecious organisms show both self and cross-fertilization, whereas dioecious plants are capable of only cross-fertilization.
All monoecious plants can produce seeds due to the presence of the female flower. On the flip side, in dioecious plants, the seed is produced by female plants only.
A type of organism that has both male and female reproductive organs on the same individual is known as monoecious, whereas a type of organism that has male and female reproductive organs on separate individuals is known as dioecious.
Monoecious plants show low genetic variations and more homozygosity due to self-pollination while there are more genetic variations and increased heterozygosity in dioecious plants due to cross-fertilization.
Jellyfish, planarians, earthworms, and slugs are examples of monoecious animals. On the other side, Mammals, reptiles, insects, and birds are examples of dioecious animals.
Monoecious organisms show uniparental reproduction. On the other hand, dioecious organisms show biparental reproduction.
Walnut, oak, hazel, squash, and corn are the examples of common monoecious plants while, Asparagus, Biloba trees, Papaya, Marijuana (Cannabis), willow, holly, Ginkgo and poplar are the examples of dioecious plants.

Monoecious and Dioecious Definitions
Monoecious
(Botany) Having unisexual reproductive organs or flowers, with the organs or flowers of both sexes borne on a single plant, as in pines and corn (maize).
Dioecious
(Biology) Having the male and female reproductive organs, especially flowers, on different individuals.
Monoecious
(Biology) Relating to or exhibiting hermaphroditism; hermaphroditic.
Dioecious
(botany) Having the male and female reproductive organs on separate plants (of the same species) rather than different parts of the same plant.
Monoecious
Having both the male and female reproductive organs in the same individual, either in different flowers or in the same or different flowers; hermaphrodite.
Dioecious
Having two distinct sexes.
Monoecious
Having the sexes united in one individual, as when male and female flowers grow upon the same individual plant; hermaphrodite; - opposed to diœcious.
Dioecious
Having male and female reproductive organs in separate plants or animals
Monoecious
Having male and female reproductive organs in the same plant or animal
Monoecious vs. Dioecious
On the basis of the presence of sex organs, organisms are divided into two types, i.e., monoecious and dioecious. These terms are used to discuss the reproductive behavior of plants. Monoecious are bisexual organisms, i.e. they have both male and female organs. On the other hand, dioecious is the unisexual organism, i.e. they have male and female reproductive organs on separate individuals. About 90% of species of plants are bisexual and called perfect flowers. They have both staminate (stamen or male part) and pistillate (carpels or female part) present on the same flower. On the flip side, dioecious plants have male and female flowers on separate plants.
Monoecious plants are capable of both cross and self-pollination whereas, dioecious plants are capable of only cross-pollination. All monoecious plants can produce seeds due to the presence of female flowers. On the other side, in dioecious plants, the seed is produced by female plants only. Monoecious plants show low genetic variations and more homozygosity due to self-pollination while there are more genetic variations and increased heterozygosity in dioecious plants due to cross-fertilization. Earthworms, slugs, and corn, etc. are examples of monoecious organisms. On the other side, mammals, birds, and papaya, etc. are examples of dioecious organisms.
What is Monoecious?
In the word “Monoecious,” Mono means “one,” and this term literally means “one house.” It is a type of organism with both male and female reproductive organisms present on the same individual. So, they are bisexual and show uniparental reproduction. Both female and male gametes are formed in the same organism and may fuse by self or cross-fertilization. Monoecious plants show less genetic variations and more homozygosity due to self-pollination. Monoecy is more commonly found in Squash, walnut, oak, hazel, corn, jellyfish, planarians, and slugs, etc.
What is Dioecious?
In the word “Dioecious,” di means “two,” and this term literally means “two houses.” It is a type of organism with male and female reproductive organisms on different individuals. So, they are unisexual and show biparental reproduction. Both female and male gametes are formed in different organisms and may fuse by only cross-fertilization. So, there are more genetic variations and increased heterozygosity in dioecious plants. Dioecy is more commonly found in Marijuana (Cannabis), Asparagus, Biloba trees, Papaya, willow, holly, Ginkgo, Mammals, reptiles, insects, and birds, etc.
