Plants



Mosses
Only mosses have a multicellular rhizoid, a root-like subterranean tissue that absorbs water and nutrients from the soil. Mosses have radial symmetry, when cut down by the middle it gives two simmilar halves. Mosses are unique bryophytes in that they have stomata; cells specialized for photosynthetic gas exchange, on their sporophytes. In addition mosses do not have true leaves or stems. Their leaf-like structures are called phyllids. They are typically only one cell thick, although in other types of species they’re many cells thick.

Ferns
A Fern generally consists of one or more fronds attached to a rhizome. A frond is a ferns leaf. A rhizome is a specialized, root-like stem. In most temperate-zone species of ferns, the rhizome is subterranean and has true roots attached to it. Fronds are attached to the rhizome by a stalk known as a stipe. The structures of the frond, rhizome, and stipe are Key importance to classify the species identification. Visible under sides of the frond are the reproductive cells, since they’re cluttered together they form brown spots. It’s reproduction isn’t quiet understood since the reproductive cells are microscopic spores.

Pine Tree
Most pines native to North America can grow as high as 197-262 ft (60-80 m). The leaves are all needle like and arise from the stem in bundles, called facicles. Each Facicles are associated with a fascicle sheath, a special tissue located at its base. Since pines have needles throughout the year, they have the potential to photosynthesize whenever conditions are suitable. They are well adapted for growth in harsh dry areas. The outer surface of the needle has a waxy layer, called a cuticle, which helps reduce evaporative water losses. Pines trees are one of many plants whose seeds are not enclosed within an ovary, known as Gymnosperms.
