Sexual selection in flowering plants. Sexual selection is described as natural selection arising through preference by one sex for certain characteristics in individuals of the other sex. Sexual selection is a common concept in animal evolution but, with plants, it is often overlooked because many plants are hermaphrodites.
They are small plants found growing in moist locations and like ferns, have motile sperm with flagella and need water to facilitate sexual reproduction. These plants start as a haploid spore that grows into the dominant gametophyte form, which is a multicellular haploid body with leaf-like structures that photosynthesize. Haploid gametes are ...

For humans, it includes the mons pubis, labia majora, labia minora, clitoris, vestibule, urinary meatus, vaginal introitus, hymen, and openings of the vestibular glands.

Euphorbia is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae . Euphorbias range from tiny annual plants to large and long-lived trees. [ 2] with perhaps the tallest being Euphorbia ampliphylla at 30 m (98 ft) or more. [ 3][ 4] The genus has roughly 2,000 members, [ 5][ 6] making it one of ...
Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms. These microorganisms include protists which use it for their locomotion. The direction of their movement is always opposite to that of the secretion of mucilage. [ 1] It is a polar glycoprotein and an exopolysaccharide.
