More Information On Flowers(Interesting!!!)

Dioecious - refers to a plant population having separate male and female plants. That is, no individual plant of the population produces both microgametophytes (pollen) and megagametophytes (ovules); individual plants are either male or female.

Androecious - plants producing male flowers only, produce pollen but no seeds, the male plants of a dioecious population.

Gynoecious - plants producing female flowers only, produces seeds but no pollen, the female of a dioecious population. In some plant populations, all individuals are gynoecious with non sexual reproduction used to produce the next generation.

Monoecious - an individual that has both male and female reproductive units (flowers, conifer cones, or functionally equivalent structures) on the same plant; from Greek for "one household". Individuals bearing separate flowers of both sexes at the same time are called simultaneously or synchronously monoecious. Individuals that bear flowers of one sex at one time are called consecutively monoecioous; plants may first have single sexed flowers and then later have flowers of the other sex. Protoandrous describes individuals that function first as males and then change to females; protogynous describes individuals that function first as females and then change to males.

Hermaphrodite - A plant that has only bisexual reproductive units (flowers, conifer cones, or functionally equivalent structures)
Subdioecious, a tendency in some dioecious populations to produce monoecious plants. The population produces normally male or female plants but some are hermaphroditic, with female plants producing some male or hermaphroditic flowers or vice versa. The condition is thought to represent a transition between hermaphroditism and dioecism.

Gynomonoecious - has both hermaphrodite and female structures.

Andromonoecious - has both hermaphrodite and male structures.

Subandroecious - plant has mostly male flowers, with a few female or hermaphrodite flowers.

Subgynoecious - plant has mostly female flowers, with a few male or hermaphrodite flowers.

Polygamy - Plants with male, female and perfect (hermaphrodite) flowers on the same plant, called trimonoecious or polygamomonoecious plants. A polygamous inflorescence has both unisexual and bisexual flowers.

Imperfect Flower
