1. cycadophyta

   Cycads are seed plants that typically have a stout and woody (ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long. Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones (strobili), somewhat similar to conifer cones. Cycads have been reported to fix nitrogen in association with various cyanobacteria living in the roots (the "coralloid" roots). These photosynthetic bacteria produce a neurotoxin called BMAA that is found in the seeds of cycads. This neurotoxin may enter a human food chain as the cycad seeds may be eaten directly as a source of flour by humans or by wild or feral animals such as bats, and humans may eat these animals. It is hypothesized that this is a source of some neurological diseases in humans. Another defence mechanism against herbivores is the accumulation of toxins in seeds and vegetative tissues; through horizontal gene transfer, cycads have acquired a family of genes from a microbial organism, most likely a fungus, which gives them the ability to produce an insecticidal toxin.Cycads all over the world are in decline, with four species on the brink of extinction and seven species having fewer than 100 plants left in the wild. The plant has a very long fossil history, with evidence that they existed in greater abundance and in greater diversity before the Jurassic and late Triassic mass extinction events.

1. cycadophyta

   Cycadophyta is a division of seed plants characterized by palm-like appearance, typically found in tropical and subtropical regions. These plants are ancient in origin and are known for their large and compound leaves and stout trunks. They reproduce using cones and have specialized male and female plants (dioecious). Despite their physical resemblance to palms or ferns, they are not related and represent a unique plant lineage.

1. Cycadophyta

   A division of GYMNOSPERMS which look like palm trees (ARECACEAE) but are more closely related to PINUS. They have large cones and large pinnate leaves and are sometimes called cycads, a term which may also refer more narrowly to cycadales or CYCAS.
