The Vascular Plants

1970
The biologist who would understand how nature works must understand how the structures and functions of living organisms are related. First, however, he must choose a group of organisms to study. Our assignment here is to describe at an introductory level some of the structures and functions of one group of living things, the vascular plants.

Vascular tissue development in plants

2019
The plant vasculature is a sophisticated system that has greatly contributed to the evolution of land plants over the past few hundred million years. The formation of the vascular system is a well-organized plant developmental process, but it is also flexible in response to environmental changes.

Vascular Pattern Formation in Plants

2010
Reticulate tissue systems exist in most multicellular organisms, and the principles underlying the formation of cellular networks have fascinated philosophers, mathematicians, and biologists for centuries. In particular, the beautiful and varied arrangements of vascular tissues in plants have intrigued mankind since antiquity, yet the organizing ...

Vascular Plants

2008
Nel capitolo del manuale di biologia vegetale applicata destinato agli studiosi di beni culturali vengono descritte e discusse le caratteristiche strutturali, morfologiche, fisiologiche, riproduttive ed ecologiche delle piante vascolari in funzione dei possibili danni causati dalla vegetazione alle opere d'arte e ai B.C. in genere.

Seedless Vascular Plants

1990
Prior to research with the electron microscope, little detailed information was available on the ontogeny and structure of the sieve elements in seedless vascular plants. About all that could be said about the mature sieve-element protoplasts in this diverse group of plants was that they generally had a very clear appearance, contained variable numbers

New Divisions of Vascular Plants

Nature, 1947
A widely used classification of vascular plants has recognized four divisions: Psilopsida, Lycopsida, Sphenopsida and Pteropsida1. The first three have been erected in the course of time out of Jeffrey's2,3,5,5a original Lycopsida. The fourth has not been changed from Jeffrey's2,4,5,5a original Pteropsida, and is further subdivided into Filicineae ...

Secretory tissues in vascular plants

New Phytologist, 1988
SUMMARYSecretory tissues occur in most vascular plants. Some of these tissues, such as hydathodes, salt glands and nectaries, secrete unmodified or only slightly modified substances supplied directly or indirectly by the vascular tissues. Other tissues secreting, for instance, polysaccharides, proteins and lipophilic material, produce these substances ...

Tracheophyte Phylogeny Vascular Plants

2016
The "Tracheophyte Phylogeny Poster – Vascular Plants - Systematics and Characteristics" is an educational tool presenting an overview of the evolutionary relationships among non-flowering vascular plants (lycophytes, monilophytes, and gymnosperms). The phylogenetic tree depicts the orders and families (lycophytes and monilophytes) and the genera of ...
