Sessile:
In botany, sessility (meaning “sitting”, used in the sense of “resting on the surface”) is a characteristic of plant parts that have no stalk.[1][2] Flowers or leaves are borne directly from the stem or peduncle, and thus lack a petiole or pedicel. The leaves of most monocotyledons lack petioles. [Wikipedia]
Noted in “Debunking the ACLU’s ‘4 Myths About Trans People’,” Colin Wright, Reality’s Last Stand:
Is sex binary? The use of the term “binary” is one that many seem to trip over. According to the dictionary definition, binary means “consisting of, indicating, or involving two.” As a biologist, I can confidently say this definition accurately describes biological sex. That is because the sex of an individual refers to one of two—and only two—functional roles that an individual may play in sexual reproduction. Males are defined as the sex that produces small, motile gametes (sperm), and females produces large, sessile gametes (ova). There is no third gamete between sperm and ova, and therefore there is no third biological sex apart from males and females. Intersex is an umbrella term that refers to external sex ambiguity or a mismatch between internal sexual anatomy and external phenotype, but it is not a third sex.
