PRAZZER- Growth and Development of Ovule and Ovary

Angiosperms undergo double fertilization. Double fertilization produces a zygote and an endosperm. Afterwards, the ovule developes into a seed and an ovary into a fruit that protects the seed(s).

Growth and Development of Ovule

            The ovule grows and developes into a seed. The zygote and endosperm are in it. The zygote continues to grow and develops into an embryo.

Gowth and Development of endosperm

            The endosperm grows and develops earlier, compared to the embryo. The endosperm is rich in nutrients and it servers as food storage which is utilized for the growth and development of the embryo. In most monocotyledons,the nutrient reservers is put in the cotyledon before seed grows and developes further.

Gowth and Development of embryo

            Growth and development of the embryo is begun with zygotic cleavage by mitosis to produce basal and apical cells. Basal cells develop into a suspensor. The suspensor function as a connector between the embryo and the outer layer of the ovule. It also allows nutrients flow from the mother plant or the endosperm. Apical cells develop into a proembryo. This is followed by embryo`s development. In then develops a stem and roots.

PRAZZER- Energy Potensial and Energy Kinetic

The energy of an object is the size of the object's ability to conduct a business. The unit of energy is the joule. Energy in the physical sciences are divided into variouskinds / types, among others:

PRAZZER- KIND OF RAIN

Rain is one form of precipitation, or derived from space fluid, such as snow, hail, dew and fog. Rain forms when separate drops fell to earth from the clouds. Not all rain water to the earth's surface, some evaporates while falling through dry air, a type of precipitation that are recognized as virga.

Rain plays an important role in orbit hydrologik in which moisture evaporates from the sea, exchanged into the clouds, gathered into clouds, then fall back to earth, and finally returned to the sea through rivers and streams to repeat the original recycling.

The amount of rain was measured using a rain gauge. He stated as the d

PRAZZER- Atom Bohr Model

Bohr Atom ModelThe fourth model of the atom which we will discuss the Bohr atom model. In 1913, Danish physicist named Neils Bohr atom Rutherford repair failures through experiments on the hydrogen atom spectrum. These experiments successfully gives an overview of state of electrons occupying the area around the atomic nucleus.Bohr's explanation of the hydrogen atom involves a combination of the classical theory of Rutherford and of Planck's quantum theory, expressed by four postulates, as follows:There are only a certain set of orbits are allowed for one electron in a hydrogen atom. Orbit is known as a state of stationary motion (settling) of electrons and is a circular path around the nucleus;As long as the electrons are in stationary trajectory, the electron energy remains so there is no energy in the form of radiation emitted or absorbed;Electrons can only move from one stationary trajectory into another stationary trajectory. In this transition, a certain amount of energy involved, the amount in accordance with Planck equation, ΔE = hv;Stationary trajectory is allowed to have the scale with certain properties, especially a property called angular momentum. The amount of angular momentum is a multiple of h/2Π or nh/2Π, where n is an integer and h Planck constant.
According to Bohr's atomic model, the electrons surrounding the nucleus in certain paths called electron shells or energy levels. Lowest energy level is the electron shell which is located in, getting out of her skin and the greater the number the higher the energy level.

MGS on smasa

A spectacular and memorable event which was held Friday padahari dated June 11, 2010 at the House of Tri Dharma Bojonegoro. The event with the theme of "traditional Javanese and Balinese" is a farewell event and an arts degree. Or the more popular by the name of MGS. The event was organized with the cooperation between schools, the school council, and the main sponsor of Omah Wood and several sponsors supporting the BNI 46, Griya Ayu Paes, MCM, Primagama, and so on.
In the event there is something different from the farewell party in general. In opening the event there are five pairs of hosts that use all five languages, namely Indonesian, Javanese, English, French, and German. Decorating the stage that there was impressed with the feel of his Javanese wayang rama picture and Sinta in the corner of the corner stage. Lighting the lamp - the colorful lights also show how the glitter of the show that night. So the event seemed a luxury. Luxury is not spared from the sound system coordination team to come from Jember.In the middle of the event, read all students - students who entered the top ten highest winning NUN. Both of science majors or even the Department of IPS. Of science majors, the first rank achieved by Ramadan Princess Calicha of XII IPA 1. Meanwhile, the first rank of social studies majors won by Lena Frances Purnama from the XII IPS 1. In the event, also held a screening of documentary films about everyday life of students - students, teachers - teachers, even though security guards. In the film recounted the activities of children - children in the lab. computer, the activities of students who play magic, romance stories as empty hours, and much more. In addition to screenings, there are also traditional dances and modern dance. For example peacock dance, dance gambyong, punjari dance, and various other dances.In addition there is also the band's performance - the band of class XI and XII. And there is also the appearance of bands from the father and teacher mother, like Mrs. Lita, Sukiswati Mother, Mother Ninik as a vocalist and accompanied by Mr. Sudibyo sebadai guitarist and vocalist, Mr. Markasim as a bassist, and Mr. Rianto as a drummer. From MGS event, it appeared berbagia invite criticism from students and students of SMAN 1 Bojonegoro namely:  Ardian R. Cipta (XII IPA 1) "Overall it looks good. However, less systematic in the order. In conceptual show still less coherent. "
 Wilda Shafira (X-7) "MGSnya good. Lightingnya cool! However, the schedule was delayed because of - because of lack of preparation. His appearance is also not definitely appear.Preparation check tools - tools are also lacking. Sometimes there are still many mistakes. "
 Manikya Pramudya (X-4) "Overall OK. But the net less rehearsal. So when going dancing or dance music does not exist. "
