5. Tissue culture
Plant
hormones encourage the advancement of agricultural experts to develop
patterns of vegetative production through tissue culture techniques. The network is extracted from the leaves, stems, roots, or other plant parts. Through this technique can produce plants that are very much in a short time.
B. Generative reproduction
Generative
is that plant breeding is to breed in abundance, namely the convergence
of male cells found in the stamens and female cells contained in the
pistil. Meets 2 cells would eventually bear fruit with the seed in 2 that dikotil. Plants that were bred in this way usually have a genetic trait that is different from the parent plant and usually decline. The process of sexual reproduction requires a male and female gametes. The process of seed plants marriages preceded by pollination and continued with the process of fertilization.
1. Open pollination in seed plants (gymnosperms) is the attachment of pollen to mikrofil (liang ovules). And a single conception.
Gymnosperms such as reproductive males and Strobilus Strobilus females.
The process of pollination in gymnosperms generally assisted by the wind. Examples of open seed plants include:

Photosynthesis is one way
Photosynthesis
is one way for the photosynthetic carbon assimilation of CO2 free
carbon bound (fixed) to gulasebagai energy storage molecules. Another way to be taken is the organism to assimilate carbon through chemosynthesis, by some sulfur bacteria.
Until now photosynthesis was studied further because there are still a number of steps that can not be explained, even though it very much is known about this vital process. The process of photosynthesis is very complex because it involves all the main branches of the natural sciences, such as physics, chemistry or biology alone.
From the observations on this event can be distinguished which one is better in the process of photosynthesis in plants using a beam of sunlight or without sunlight. Photosynthesis lasts in two stages, the reaction Teran and dark reactions. Reactions involving bright sunlight while the dark reaction does not involve sunlight, chemical reactions involving dark. After conducting field observations for the reaction Tarang and in the laboratory for the dark reaction

Photosynthesis is the process
Photosynthesis is the process of formation in plant foods with the help of sunlight. The ingredients of photosynthesis is glucose, CO2, and other organic materials. In this lab, observations of objects used is Hydrilla verticillatai. Hydrilla verticillata is included in monocotyledoneae class, race and ethnicity hydrocharitaceae helobiae. Hydrilla verticillata is aquatic plants that live in fresh water. Hydrilla
verticillata is used as an object of observation for water plants
including plants that are directly related to water and oxygen. And water, oxygen is a factor supporting the course of photosynthesis.

Oxygen is only produced
Oxygen is only produced from the photosynthesis of water, instead of carbon dioxide. This was first revealed by C.B. Neil van who studied photosynthetic bacteria in the 1930's. Photosynthetic bacteria, in addition to cyanobacteria, use does not produce oxygen as it uses ionization or hydrogen sulfide.At
the same time the ionization photosystem II, photosystem I light also
ionizes, releasing electrons are transferred along the electron
transport chain which ultimately reduces NADP into NADPH.
Dark Reaction
ATP and NADPH produced by the photosynthetic process triggers a variety of biochemical processes. In plants, the biochemical triggers is the Calvin cycle that binds the carbon dioxide to form ribulose (and then into sugar such as glucose). This reaction is called the dark reactions because it does not depend on the presence or absence of light so that it can occur even in the dark (without light). (Hardianto, 30: 2004)

Light reaction is a process to produce
Light reaction is a process to produce ATP and reduction NADPH2. This reaction requires water molecules. The process begins with the capture of photons by the antenna pigments.Chlorophyll
pigments absorb more visible light to blue (400-450 nanometers) and red
(650-700 nanometers) than green (500-600 nanometers). The green light will be reflected and captured by our eyes causing a sensation that the leaves are green. Photosynthesis will produce more energy at a particular wave length of light. This is because the shorter wavelengths greater energy savings.
In the leaves, the light is absorbed by chlorophyll molecules to be collected at the reaction centers. Plants have two types of pigments that function as active as the reaction center or photosystem II and photosystem I. Photosystem Photosystem II consists of chlorophyll molecules that absorb light with a wavelength of 680 nanometers, 700 nanometers whereas photosystem I. The two photosystems this will work simultaneously in photosynthesis, such as the two batteries in a flashlight that works mutually reinforcing.
Photosynthesis begins when light ionizes the chlorophyll molecules in Photosystem II, releasing electrons are transferred along the electron transport chain. The energy of the electron is used for photophosphorylation that produce ATP, the energy exchange in the cell unit. Photosystem II reaction causes a deficit or lack of electrons that must be replaced immediately. In plants and algae, the electron deficiency is filled by electrons from the ionization of water ionization occurs simultaneously with chlorophyll. The result is an electron ionization of water and oxygen.

Photosynthesis is a biochemical
Photosynthesis
is a biochemical process in which plants, algae, and some bacteria used
to produce energy (nutrients) using light energy. Nearly all living things depend on energy produced from photosynthesis. As a result of photosynthesis is very important for life on earth. Photosynthesis is also credited with producing most of the oxygen present in Earth's atmosphere.
Organisms that produce energy through photosynthesis (photos meaning light) is called fototrof. Photosynthesis is one way for the photosynthetic carbon assimilation of CO2 free carbon bound (fixed) to gulasebagai energy storage molecules. Another way to be taken is the organism to assimilate carbon through chemosynthesis, by some sulfur bacteria.
Until now photosynthesis was studied further because there are still a number of steps that can not be explained, even though it very much is known about this vital process. The process of photosynthesis is very complex because it involves all the main branches of the natural sciences, such as physics, chemistry or biology alone.
In plants, the main organ of photosynthesis is the site of the leaf. But in general, all the cells that have the potential to establish a chloroplast reaction. At the site of the photosynthetic organelle is, exactly in the stroma. Of photosynthesis (called photosynthate) is usually sent to a nearby tissues first. Basically, a series of reactions of photosynthesis can be divided into two main parts: the light reaction (because it requires light) and dark reactions (do not require light but require carbon dioxide).
