Gymnosperms are an intriguing group of plants, yet in many ways they are not well known. Most people can recognize a pine, with its familiar woody cones, but they may not know that this and other conifers are gymnosperms. Or, they may think that conifers are the only plants in the gymnosperm group. Undoubtedly the often large-flowered angio-sperms ...
The ancestors of gymnosperms most likely evolved from a group of plants called the seed ferns (pteridosperms), which are known only from the fossil record. These were the first plants to reproduce by seeds, despite looking deceptively like ferns. (True ferns reproduce from spores rather than seeds.) Early seed plants bore their seeds directly on le...
Ginkgo biloba is the sole living species of the once widely distrib-uted order Ginkgoales and is often called a “living fossil.” This plant has fascinated botanist for centuries because it represents a unique set of characteristics that alludes to both the cycads and conifers but which represents a unique lineage within the gymnosperms. Ginkgo’s fl...
conifers are the most conspicuous group of gymnosperms, containing 7 families and more than 600 species. They tend to dominate forests in the northern Hemisphere and have a rich and diverse existence in the Southern Hemisphere, but are reduced in numbers in most tropical environments. conifers are such a highly vari- The bract–scale structure of a ...
The Gnetales are perhaps the most enigmatic group of the gymnosperms, which, considering the mysteries we have already encountered, is no minor statement. Their phylogenetic posi-tion within the seed plants remains unresolved and their morphology is puzzling. This order of plants is made up of 3 families—Ephedraceae, Gnetaceae, and Welwitschiaceae—...

Aug 3, 2023 · Characteristics of Gymnosperms. The gymnosperm is a woody plant with seeds on the inner side of scale leaves that are usually arranged spirally to form cones or strobili but without flowers. Intermediated group between Cryptogams and Angiosperms. As gymnosperm lacks an ovary, it can’t produce fruit.
May 2, 2018 · Coniferophyta. Gymnosperms: Cycad Cones. Maxfocus/iStock/Getty Images Plus. The Coniferophyta division contains conifers, which have the greatest variety of species among gymnosperms. Most conifers are evergreen (retain their leaves throughout the year) and include some of the largest, tallest and oldest trees on the planet.

Oct 31, 2023 · Characteristics of Gymnosperms. Gymnosperms are seed plants adapted to life on land; thus, they are autotrophic, photosynthetic organisms that tend to conserve water. They have a vascular system (used for the transportation of water and nutrients) that includes roots, xylem, and phloem.
