EVEN in these days of specialisation, no real botanist dismisses the Gymnosperms from his field of study. They still possess an inherent interest, although for a hundred years they have been ...

The botanist in me wants to remind you that gymnosperms are an ancient group of plants, showing up about 380 million years ago. This was the Devonian period…which is most well known for being ...

Proceedings of the American Academy of Arts and Sciences Vol. 54, No. 2, Sep., 1918 Size Variation in Tracheary Cells: I. A ... Size Variation in Tracheary Cells: I. A Comparison between the Secondary ...

Insect pollination is a decisive process for the survival and evolution of angiosperm (flowering) plants and, to a lesser extent, gymnosperms (without visible flower or fruit). There is a growing ...

But gymnosperms also comprise gnetales (like W. mirabilis), the palm-like cycads and ginkgo, also known as the maidenhair tree. When dinosaurs roamed Earth, they walked among the gymnosperms ...

There are two main types of plants: flowering plants, known as angiosperms, and non-flowering plants, known as gymnosperms. The flower bud and fruit in the fossil are both clear indicators that F.

Trees are typically organized into two categories: hardwoods (angiosperms) and softwoods (gymnosperms). A new study suggests that there is a third type of wood—known as “midwood”—that ...

Fine roots (≤2 mm in diameter), the main conduit for resource uptake in the plant-soil continuum, are one of the most metabolically active organs of trees. Due to the difficulty of directly ...

Also, the study’s results provide tantalizing new insights into the evolutionary pathway that flowering plants took 135 million years ago when they split off from gymnosperms, the “naked-seeded” plant ...

The fossil record shows us that around 100 million years ago, during the Cretaceous period, a huge variety of angiosperms came onto the scene and replaced gymnosperms as the dominant type of plant ...

During the Jurassic, a new method of plant reproduction evolved. Gymnosperms, cone-bearing plants such as conifers, allowed for wind distribution of pollen. This bisexual reproduction allowed for ...
