Making cones and seedsLearn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.In simple terms, this means that cycads do not produce true flowers or fruit, just one or more large seed cones. Cycads are dioecious, so cycad cones are either male or female. Botanically speaking, the male cone is a microsporophyll and the female cone is a megasporophyll.www.marriedtoplants.com/cycads/cycad-cones-rep…Cycads are non-flowering plants that are actually more closely related to conifers than to palms or any other flowering plants. They reproduce by making cones and seeds. All cycads are dioecious, which means they are either male or female, and never both.davesgarden.com/guides/articles/view/41In the more evolutionarily recent angiosperms (flowering plants), the seed is enveloped by a coat or fruit which originates from the ovary. All species of cycads are dioecious, meaning the male and female reproductive structures are borne on separate plants.science.jrank.org/pages/1921/Cycads-Life-cycle.htmlTheir reproduction is very primitive in that they rely on flagellated motile male gametes (spermatozoids), a feature linking them with other plants fertilized by motile flagellated sperm (zooidogamous), such as ferns, club mosses, and other vascular cryptogams.www.britannica.com/plant/cycadophyteReproduction and dispersal Cycads produce separate male and female plants with distinct cones. Cones are often brightly colored in reds, oranges and yellows. Pollination is believed to be mostly completed by weevils and small bees which are attracted to seeds by heat and scent.basicbiology.net/plants/gymnosperms/cycads- People also ask

Cycad - Wikipedia
Cycads /ˈsaɪkædz/ 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 slowly and have long lifespans. Because of th…
