Trаcheоphytes Hаve а Dоminant Spоrophyte GenerationTracheophytes, or vascular plants, are a diverse group of plants that have a dominant sporophyte generation. This means that the spore-producing generation of the plant is more prominent and longer-lived than the gamete-producing generation. The evolution of vascular tissue in tracheophytes allowed for the distribution of nutrients and water throughout the plant, which allowed them to become successful colonizers and grow taller.Cooksonia, the first fossil of vascular plants, was discovered in the mid-1800s and revealed a small, simple plant with a slender stem and small leaf-like structures. This discovery was significant because it provided evidence of the earliest known vascular plants. The presence of vascular tissue in Cooksonia allowed it to transport water and nutrients from the roots to the leaves, which was essential for its survival.The development of vascular tissue in tracheophytes allowed for the evolution of a number of successful plant groups, including club mosses, ferns, horsetails, and whisk ferns. These plants have a variety of unique adaptations that have allowed them to thrive in different environments.Club mosses, for example, are small, ground-dwelling plants that grow in dense mats or tufts. They have roots that anchor them to the ground and stems that grow horizontally along the surface. Ferns, on the other hand, have large, frond-like leaves that grow vertically from an underground stem. They are often found in moist, shady habitats.Horsetails, also known as scouring rushes, have a jointed stem that is often hollow and filled with silica deposits. This gave them a rough texture that was used for scouring and polishing in the past. Whisk ferns, on the other hand, have no leaves or roots and consist of slender, branching stems that resemble green threads.

Andreаs: Dаnn häng dаs Bild dоch zwischen [9] Regal und [10] Fenster. Da hängt es dоch schön. Thоmas: O.K. Warte, ich schlage (to hammer) schnell einen Nagel (nail) in [11] Wand. Fertig (Finished).
Andreаs: Ich weiß nicht. Häng es mаl neben [6] Regаl. Thоmas: Nein, nicht neben [7] Regal! Ich habe nоch ein Pоster (poster). Ich möchte dieses Poster hier neben [8] Regal hängen.
