Wikipedia

  1. cycads

    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.

Examples of cycads in a Sentence

  1. Caleb Marshall Brown:

    The lack of horsetails, and rarity of cycads and conifers is surprising, given that these are very common in the surrounding flora, even within ferns, it looks like Borealopelta may have had a preference for certain types of ferns, while ignoring others.

  2. Paul Barrett:

    Instead of just feeding on mushy ferns or low-growing horsetails, it means they might have been much more important in munching tough plants like conifers or cycads, which suggests they may have been feeding on quite different things, maybe living in different environments from time to time, and even potentially acting as vectors for moving seeds and fruits around for those different types of plants.
