Introduction

In this research paper we will talk about plants and there function, I will do a description detail of the plant of there characteristics, vascular plant, non-vascular plant, plant development also there will be images and were there I findthat information

TRAITS OF THE PLANTS:
Plants are able to absorb nutrients and water from the ground. They can create their own energy through photosynthesis, with occur inside the chloroplasts. Plants go through cellular respiration just like animals, except they take in carbon dioxide and convert into oxygen. Plants need water to like. They plants also contain an extra covering called cellwall. It acts just like the cell membrane, except that is much hardier
NON-VASCULAR PLANTS:
A non-vascular plant is a term for those plants without a vascular system (the xylem and the phloem).Non-vascular plants means that they don´t have specialized tissue. All plants have a life cycle with an alternation of generation between a diploid saprophyte and a haploid gametophyte, but non-vascularplants are the only plants that have a dormant of gametophytes. The term non-vascular plant is no longer used in scientific nomenclature. Non-vascular plants include two distantly related groups:
* Mosses
* Liverworts
* Hornworts
Because these plants lack the water-conducting tissue, they can´t become as big as most vascular plants.
In the past, the term nom-vascular plant included notonly all algae, but also the fungi.

VASCULAR PLANTS:
Vascular plants are those plants that have lignified tissues for conducting water, minerals and photosynthetic products through or throughout the plant roots, stems and leaves. Vascular plants include the ferms, clubhouses, flowering plants, conifers and other gymnosperms. They make up the majority of plants found on the earth today, withthe exception of mosses and liverworts.
CONIFERS:
The conifers are one of 13 or 14 division level taxa within the kingdom plantae. All extant conifers are woody plants, the great majority being trees with just a few being shrubs. The division contains approximately eight families, 68 genera, and 630 living species. Trough the total number of species is relatively small, conifer are of immenseecological importance. They are the dominant plant over a huge land, also can live in similar cool climates. For timber and paper production, the wood of the conifers is known as softwood.
FLOWERING PLANTS:
The flowering plants are the most diverse group of earth plants; they are only the existing groups of seed producing plants. The antecedents of flowering plants divergedfrom gymnosperms around 245–202 million years ago, and the first flowering plants known to exist are from 140 million years ago.
Leaf:
The leaf is an above-ground plant organ specialized for the process of photosynthesis. As the leaf evolutionary trait the chloroplast get more light and is better the absorption of carbon dioxide at costs of losing water. IN Devonian period, plants didn´t have levees or flat stems. Inleaves are also plants where transpiration and guttation take place. Leaf stores food and water
Plant support and transport:
Roots, stems, xylem and phloem. How they all contribute to the support and transport in plants.
Roots:
The roots take the minerals of the land some of the most important minerals are potassium, nitrate and phosphate. The soil is often fewer minerals than root it,...
