Life of plants are are surviving factor!
January 16, 2010 by pindersbean
Humans as we are, rely on plants like no other, they provide necessary factors that help us as a species to survive. They provide oxygen so we can breathe, food to eat, medicine for healing, shelter for warmth, and to help not just us survive but an arrangement of other living organisms to survive and thrive.
Through their way of making energy to survive through photosynthesis they give back to us the oxygen that fills our lungs for us to survive. Not only is oxygen the only benefit we get from them but a large variety is at hand as they supply us with food and we all no we cant survive with out that, the trees give us timber for building shelter to protect us from the dangerous conditions and season around the world and paper for writing, as well as some plants like Aloe Vera help heal injuries we substain during every day life. Last but not least they make the Earth substainable and livable for all organims and creates alike that live amoung he lands.

Preventing Erosion.
January 16, 2010 by pindersbean
Plants that are native to an area when planted and grow over a period of time will adapt to changes that werent there before.
Various types of plants help their environment grow, survive, and prosper, for example common plants like bushes, shrubs, and roots of trees and plants help keep the ground, dirt, and soil fresh by supply nutrients through roots into the ground and keep it thriving for other plants to grow and mature.Roots from trees will strenghtne the soil they are planted in for they keep the soil in place so it doesnt slide or move around to much. Grasses and certain other plants with large surface areas create a shield and help prtect the ground for over watering. Plants that are native and planted to river or lake sides have many benefits that contribute to the land. These benefits include drought resistance, allowing them to survive if a river/lake would overflow and they protect the soil around them from erosion.

Plants making a baby?
January 16, 2010 by pindersbean
Plants either reproduce like us sexually or reproduce another way which is called asexually
If a plant is to reproduce sexually it will need a mate for a new plant to be able to form. Each individual one male and one female must supply a gamete. The male plant must transfer it’s DNA or gamete to the female plants ovules to start the process of forming a new life, this is called pollination. When this step happens the fertilization takes place in the female plants ovules. When all is done the seed is formed in a fruit and once the fruit ripens or mutures it will be released to be planted and grow and become a adult plant.
If a plant reproduces the other way by asexual reproduction then it needs it self. The plant that does reproduce asexually will basically make a copy of its self, unless there is a mutation in its DNA. There are many ways a plant can reproduce asexually:Fission: A cell dividing to make a replica of itself. Spore: Fungi will grow and create spores and when the time is right they will spread amoung the land and grow. Budding: When a plant grows out and splits into a new individual.

Plant circulation.
January 16, 2010 by pindersbean
The vascular system is made up of xylem and phloem tubes. Their structure is very much similar to pipes, because they transport water, nutrients, and minerals to different parts of the plant.The Phloem tubes are like pipes because they link up end to end and as the plant grows more phloem’s grow and connect with the ones before them creating a chain. Xylem and phloem tubes grow into vascular bundles as wells as supporting and protective cells. Xylem tubes are found near the center of the roots and stem while the phloem tubes grow on the exterior walls of the stem and roots, but this does not apply to dicots as these tubes are intertwined through the plants stem and roots.
Compared to a humans or animals vascular system the plants isnt as complicated and has less parts involved in the process as plants use these tubes to preform the task bringing the necessary nutrients, minerals and bring water through out the plant. Animals rely on so much more to preform this task with differnet parts and organs.

Good ol’ Oxygen!
January 15, 2010 by pindersbean
Do plants breathe in air like us humans and the animals around us? Well yes plants do breathe in air like us. But unlike humans and animals plants breathe rather differnet as they must preform photosynthesis for them to resperate and take on air. Photosynthesis will produce food, make energy, use water and carbon dioxide, and release oxygen as respiration will use up the food, energy that was made during photosynthesis, produce water and carbon dioxide, and use oxygen. Photosynthesis will only happen wen light either sun or artifical is present but resperation with occur at any time during day or night.
The differnet breathing pattern of a plant occurs like this Carbon dioxide that the plant breathes in will enter into the stomata on the underside of a leaf, already waiting inside the stomata is oxygen the was made, when the carbon dioxide enters in, the oxygen filters out diffusing each other, the carbon dioxide will then go further into the plant and will be locked away until it is needed for photosynthesis or other plant functions.
As you can see is not just how we breathe air is different but the amount of organs each one uses, plants use only a handful of organs to breathe in and exhale while humans and animals go through an arrangement of organs that help us breathe. So compared with plants it is easier to follow the path of air.

Monocots and Dicots
January 15, 2010 by pindersbean
Plants are classified under to main groups monocots (monocotyledons) and dicots (dicotyledons). These two groups have many differences as listed:
Monocots: 1. Monocots plants are made up in threes 2.The number of pollen monocots contain is one 3. The number of leaves in a seed is one 4. Vascular tissues are scattered in its structure
Dicots: 1. Dicots plants are made up in fours and fives 2. The number of pollen dicots contain is three 3. The number of leaves in a seed is two 4. Vascular tissues are in circular sets
Examples of monocots are: rice, wheat, sugar cane, corn and the lily is part of this family.
Examples of dicots are: roses, cherry blossoms, and fruit trees.

Classification of plants.
January 15, 2010 by pindersbean
Gymnosperms: include the winter trees conifers such as pine spruce and fir trees. The male and female reproductive parts on most conifers are located on their cones they grow. The male cones have reproductive pollen on the cones and when the wind blows the pollen is carryed to female cones. Gymnosperms produce “naked” seeds on the scales of the cones.
Angiosperms: are also called flowering plants; their flowers produce both male and female sex cells. Fertilized cells form within an ovary which then forms a fruit. The ovary in an angiosperm protects the fetile seeds that will in time mature into fruits.

Roots!
January 15, 2010 by pindersbean
The roots play a very important role in a plant for roots are the transportation station for getting the water out of the soil and to help surport the plant to the ground. There are many different roots for many of the different plants, there is fourteen different types of roots altogether(Adventitious roots, Aerating roots, Aerial roots, Contractile roots, Coarse roots, Fine roots, Haustorial roots, Propagative roots, Proteoid roots, Stilt roots, Storage roots, Structural roots, Surface roots, Tuberous roots.)
In the root system their are two main root types the primary and secondary root systems which work together to surport the plant. They gather water and nutrients deep with in the soil to substain life and grow.
The roots grow like everything else over time and over time roots will sprout out of the seed and burrow them selfs deep with in the soil gathering water and nutrients it needs to further its growth. As the roots become long think and strong they are able to stable them selves the plant can grow upwards now.

Stems.
January 15, 2010 by pindersbean
The main structural part of a plant is the stem, it acts like a straight highway going up and down. It holds the plant in place and straight and is able to transport the necessary nutrients to the different parts of the plant.
The stem is made out of three main tissues with differnt jobs and functions. The dermal tissue covers the outer surface of the stem covering it in a protective layer so the plant wont be hamred, it acts as a control base to exchange gases, and as well as make the stem water proof. The ground tissue usually consists mainly of parenchyma cells and fills in around the vascular tissue. It sometimes is used in the process of photosynthesis. Vascular tissue is the foundation tissue of a plant giving it the strenght to surport itself aswell as it does long transportation of energy.

Leaves.
January 14, 2010 by pindersbean
Function: the leaf does three main jobs for the plant that they are attached to. They are the site where photosynthesis takes place at which the leaf absorbs light and carbon dioxide to produce sugar which is food for the plant. When the sugar or glucose is made it is converted to energy the plant needs to survive. As well as the leaf is where oxygen is released as carbon dioxide is absorbed.
Types:according to petiole: petiolated-stalked, sessile-unstalked. According to blade: simple leaf and compound leaf. According to edge: entire, sinuate, dentate, serrate, lobed. According to shape of blade: elliptic, lanceolate, ovate, cordate, hastate, linear. According to veins: parallel veins, pinnate, aplmate. According to arrangement along the stem: alternate, opposite, whorled, rosulate.
Structure of a leaf: the leaf on every or most plants is like an onion as the leaf has many layers to it which are extremely thin and impossible to with the naked eye. The leaf contains the layers, top- the cuticle, upper epidermis, palisade mesophyll cell, middle- bundler sheath cell, xylem, phloem, veins, bottom- lower epidermis, spongy mesophyll, cells, guard cell, stoma, cuticle.
