Structure and Function of Stem

Rod on plants have shape and size are very diverse. There branched stems and some are not branched. There is a rod that is small and some are very large in size, such as the type of Giant Sequoia trees. This tree has a height of 85 meters with an estimated age of about 2200 to 2700 years. This tree is considered to be the largest tree in the world in terms of volume. The volume of this tree in 2002 amounted to 1487 cubic meters. Sherman tree with Giant Sequoia type, located in Sequoia National Park in Visalia, California.

Stem usually serves to support the parts of a plant that is above ground, uphold and strengthen the plant body, with ramifications extending the field of photosynthesis, road transport water and minerals from ground, and the results of photosynthesis can be distributed to all parts of the plant until to roots. In addition, as a place to store food reserves. For example, the sugar cane plant, cactus, and potatoes. Stem can also serve as a breeding tool such as cassava stems, ginger, and mango crops.

Structure and Function of Root

Morphological structure is a picture of the outside of the body of an organism. The structure of higher plants, such as Angiosperm and Gymnosperm can be described as follows. Morphological structure of higher plants generally consist of roots, stems, and leaves. At a certain stage in its development, plants can form flowers, fruits and seeds. The structure of plant morphology Angiosperm group is related to the condition of the environment in which his life. At the same time, plants have to extract resources from the land and air. Water and minerals from the ground, while the air is where the availability of CO2 and sunlight can not penetrate the soil. Therefore, the plant has a root system under the ground and shoot system is above ground level. Each system need each other.

Shouts can improve our energy

People learn in martial arts there is no harm while learning vocal as a fighter have to yell if it wants to powerful movements, according to the study of muscle strength will rise as shouting.
Shouted influence on muscle strength demonstrated in a recent study at Iowa State University, in the study, proving that the grip of the hands of fighters increased when coupled with shouts and if coupled respiration.

Scientific Fact 7

                                           How To Classify Element?

     Element on Earth are as many as ±110 elements. Every element has unique atomic structure which determines their chemical properties. Eighty percent of all element are metals.

    In 1869 a Russian scientist Dmitri Mendeleyev devised a way to arrange elements so that their man properties can be seen at once. This method developed into periodical table used now. Periodical table arranges elements in rows according to atomic numbers and in columns according similarity in chemical properties.

Matter

     In the last post, I discussed the particles that make up matter, now we will discuss the matter in detail

     Matters can be found in daily life around you. You can use matters fulfil you needs. When hungry you need food, when thirsty you need water. You also need dirt, rocks or sand to building house.

     Soil, rocks, paraffin, gasoline, wood, cloth, and your own body and also various materials you see everyday are matter. The various forms of matters have one similarity, which is having mass and occupying space. So, matters are everything which has mass and volume (occupying space).

     All matters in nature will experience change, nothing is eternal. Matter will experience change in mass, volume and form, even change to another matter.For example, water evaporates , wood burns into ashes, corpse change into dirt, and fruits root. Therefore, the only thing that eternal in only the one and only God. Matter is classified into 2 large groups, which are pure substance or single substance and mixture.

Scientific Fact 6

                       Air-Fueled Battery

     Now design new air-fueled energy storage with energy storage capacity is ten times longer available. New direction this field could pave the way for a new generation of electric cars, mobile phones and laptops.

     Research funded by the Engineering and Physical Science Research (EPSRC), led by researchers from the University of St. Andrews working with Strathclyde and Newcastle.

                 Pill That Can Avoid Obesity

Alessandro Sannino

Nowadays, many people have already gotten obesity. Obesity occurs due to excess intake of calories your body, thus body is unable to process all those calories. So the calories are not processed it will come absorbed and flows through the blood vessels. The more calories that are not processed will settle in the whole body.The obesity suffer is easy to get illness, such as high blood pressure. Therefore, obesity should immediately be avoided. There are many ways to avoid obesity. One of the new inventions in medical area pill that can grow 1,000 times of the original size. Italian scientist, named Alesandro Sannino, develops this pill. He developed the pill to make a fell satiation. If the pill is consumed 30 minutes before eating, then the one who consumed it will not need to eat in large potion of food. Thus, the resulting calories from foods that are not too big to swallow. that obesity can be avoided.

Structure and Function of Plant Tissue

     Tissue in plants can be grouped into two categories, namely (1) meristematic tissue or embryonic tissue and (2) permanent tissue. Meristematic tissue is the tissue of young active cells constantly divide to form the primary structure on the plant, while the permanent tissue is a tissue that has undergone differentiation. Permanent tissue consists of simple tissue and complex tissue. Simple tissue include parenchymal tissue, chollenchyma tissue, and sclerenchyma tissue. Complex tissue include dermal tissue and vascular tissue.

A. MERISTEMATIC TISSUE
       Meristematic tissue is the tissue cells are able to divide by mitosis continuously (are embryonal) to increase the number of cells in the plant body. Meristematic found in certain parts of the plant. In general, the cells making thin-walled meristematic tissue, and relatively rich in protoplasm. Meristematic cell vacuoles are very small and scattered throughout the protoplasm. This tissue consists of cells that are not differentiated. The ability of meristematic tissue to mitosis continuously causes plants to grow tall and big. Based on where the plant meristematic tissue divided into three types: apical meristematic, lateral meristematic, and Intercalary meristematic.
