Chlorophyll / Green Substance On The Leaves

Leaves are one of the plant organs that grow from twigs, usually green (containing chlorophyll) and mainly serves as a catcher of energy from sunlight for photosynthesis. Leaves are important organs for plants in their life because plants are obligate autotrophs, leaves must supply their own energy needs through the conversion of solar energy into chemical energy.

Understanding Chlorophyll

Chlorophyll or green leaf substance is a pigment possessed by various organisms and become one of the major role molecules in photosynthesis. Chlorophyll gives a green color to the leaves of green plants and green algae, but also possessed by various other algae, and some groups of photosynthetic bacteria. Chlorophyll molecules absorb red, blue, and purple light, and reflect green and slightly yellow light, so the human eye receives this color. In terrestrial plants and green algae, chlorophyll is produced and isolated on a plastide called a chloroplast.

Glucose is a type of sugar and provides a source of energy for plants to support various functions related to growth and development.

For example, for leaves to grow larger and flower buds emerge from the stem, glucose must be present for the basic energy needs of plants. Without glucose, plants will not be able to provide food for various parts. The creation of glucose depends on a pigment called chlorophyll. With certain functions, chlorophyll is considered a very important pigment or substance.

The process of photosynthesis is the only way for plants to produce their own food, survive, and grow. With sunlight, the chlorophyll content of the plant will then be activated and change the water absorbed by the roots.

Through the process of making these foods, plants will be able to have other branches or other leaves. Some plants will also thrive and flower as well as fruit due to the important chlorophyll contributions in the conversion of water into glucose as an energy source.

Along with energy production for growth and development, chlorophyll also helps convert carbon dioxide to oxygen. Extra carbon dioxide from the environment will be absorbed by plants through chlorophyll pigments.

Function of Chlorophyll Chemistry

The function of chlorophyll in tumbuah is to absorb light and transfer through plants during photosynthesis. Chlorophyll in tumbuah is found in the thylakoid in chloroplasts. Chlorophyll uses sunlight to make sugar. This is a key substance in the chloroplast, which is a center with the production of food from plant cells. Sunlight on chloroplasts in plants is absorbed by chlorophyll and then combined with carbon dioxide and water to make glucose, or sugar. This process also creates oxygen, which animals use in their own respiration.

This process also creates oxygen, which animals use in their respiration. Mitochondria then use the sugar contested by chlorophyll to convert it into energy that can be used by plants. Stroma regulated the intake of carbon dioxide from the plant, which is essential for all processes.

Chlorophyll is also not a structure that uses light. Algae have phycoerythrin, and chocolate algae use fucoxanthin.

Chlorophyll absorbs all the colors of sunlight other than green, so they look green when viewed by the human eye. The green color is what is reflected. The leaves slowly lose their chlorophyll during the fall because the process will not have enough sunlight to complete the process, and they need energy.

Chemical Structure Chlorophyll

Kinds of chlorophyll

In the plant obtained a variety of pigments that absorb light energy. Photosynthetic pigments are present in chloroplasts comprising chlorophyll a, b, santofil, carotenoids, bacteriochlorophils in bacteria. These pigments absorb different colors or light waves. Each one absorbs maximum at a certain light wave. Pigments generally have maximum absorption at short light waves as well as lengths. To maximize the absorption of light energy, there is a group of light harvesters called the antenna that consists of various pigments, the most pigment in chloroplasts is chlorophyll. Chlorophyll is a green pigment contained in chloroplast. These pigments are useful for carrying out photosynthesis in plants. Various forms and sizes of chloroplasts are found in various plants (Salisbury and Ross, 1995). In high-level plants there are 2 kinds of chlorophyll that is) are dark green and light green. Chlorophyll-a and b most strongly absorb light in the red part (600-700 nm), while the least green light (500-600 nm). While the blue light from the spectrum is absorbed by carotenoids.

So my writing about "chlorophyll / green substance on the leaves". may be useful.
