Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO2, and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis. \n\n Photosynthesis takes place primarily in plant leaves, and little to none occurs in stems, etc. The parts of a typical leaf include the upper and lower epidermis, the mesophyll, the vascular bundle(s) (veins), and the stomates. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there. They serve primarily as protection for the rest of the leaf. The stomates are holes which occur primarily in the lower epidermis and are for air exchange: they let CO2 in and O2 out. The vascular bundles or veins in a leaf are part of the plant's transportation system, moving water and nutrients around the plant as needed. The mesophyll cells have chloroplasts and this is where photosynthesis occurs.The parts of a chloroplast include the outer and inner membranes, intermembrane space, stroma, and thylakoids stacked in grana. The chlorophyll is built into the membranes of the thylakoids. \n\nChlorophyll looks green because it absorbs red and blue light, making these colors unavailable to be seen by our eyes. It is the green light which is NOT absorbed that finally reaches our eyes, making chlorophyll appear green. However, it is the energy from the red and blue light that are absorbed that is, thereby, able to be used to do photosynthesis. The green light we can see is not/cannot be absorbed by the plant, and thus cannot be used to do photosynthesis. \n\nThe overall chemical reaction involved in photosynthesis is: 6CO2 + 6H2O (+ light energy)  C6H12O6 + 6O2. This is the source of the O2 we breathe, and thus, a significant factor in the concerns about deforestation.\n\n  \n\n\nThere are two parts to photosynthesis: \n\nThe light reaction happens in the thylakoid membrane and converts light energy to chemical energy. This chemical reaction must, therefore, take place in the light. Chlorophyll and several other pigments such as beta-carotene are organized in clusters in the thylakoid membrane and are involved in the light reaction. Each of these differently-colored pigments can absorb a slightly different color of light and pass its energy to the central chlorphyll molecule to do photosynthesis. The central part of the chemical structure of a chlorophyll molecule is a porphyrin ring, which consists of several fused rings of carbon and nitrogen with a magnesium ion in the center. \n The energy harvested via the light reaction is stored by forming a chemical called ATP (adenosine triphosphate), a compound used by cells for energy storage. This chemical is made of the nucleotide adenine bonded to a ribose sugar, and that is bonded to three phosphate groups. This molecule is very similar to the building blocks for our DNA. \nThe dark reaction takes place in the stroma within the chloroplast, and converts CO2 to sugar. This reaction doesn't directly need light in order to occur, but it does need the products of the light reaction (ATP and another chemical called NADPH). The dark reaction involves a cycle called the Calvin cycle in which CO2 and energy from ATP are used to form sugar. Actually, notice that the first product of photosynthesis is a three-carbon compound called glyceraldehyde 3-phosphate. Almost immediately, two of these join to form a glucose molecule. \n\nMost plants put CO2 directly into the Calvin cycle. Thus the first stable organic compound formed is the glyceraldehyde 3-phosphate. Since that molecule contains three carbon atoms, these plants are called C3 plants. For all plants, hot summer weather increases the amount of water that evaporates from the plant. Plants lessen the amount of water that evaporates

Trees are phototrophs, they produce their own food by using carbon dioxide, water, and sunlight.

chloroplast contain membbranous structures which are pilled in stacks called grana\ngrana contain the light-trapping pigment chlorophyll. chlorophyll is the most abundant photosynthetic pigment in plants\ngrana are embedded in a gel-like matrix called stroma\nstroma is the site where the dark reaction occur and the enzyme responsible for the dark reaction of photosynthesis also found here\nstarch grains which act as a temporary storage for the products of photosynthesis are also found in the stroma\n\nfor more extra information try to find it at wikipedia

Good question. \nGrass and most other plants are green because they contain a pigmentknown as chlorophyll. The chlorophyll is used in the process of photosynthesis where a plant produces sugar in the presence of sunlight. In fact the word 'photosynthesis' means literally to\nsynthesize or 'make' from light (photo).  \n\nI hope this helps :-D

1. Chloroplasts: it is the site of photosynthesis.\n \n2. Vacuole: they are storage sites within a plant cell.

Molecules in plants consist mostly of a backbone of carbon atoms, generally also bonded to oxygen and hydrogen atoms (and, to a lesser degree, to atoms of nitrogen and other elements). Most of these molecules are not colored. For example, sugars and starches contain only carbon, hydrogen and oxygen and they are not colored. But some molecules are colored, such as chlorophyll which is green and responsible for the green color of foliage and leaves. The green color of chlorophyll is critical to our life on earth. Chlorophyll facilitates photosynthesis, converting carbon dioxide in the atmosphere to the oxygen we breathe. Chlorophyll appears green because it absorbs red light from sunlight and it is this absorbed energy which drives photosynthesis. So color in plants is more than decorative: it is essential to life.

It's the 1st part of photosynthesis, the light reactions. They need the energy from the sun to convert it into chemical energy to serve as the reactants for the 2nd part, the Calvin cycle.\n\nGood luck with your homework!! :)

As per above, red and blue wavelengths are generally the most important because chlorophyll absorbs these colors to a greater extent.  Greens and yellows are often reflected, resulting in the colors of plants that we see.  When the color of light is red or blue, chlorophyll are more apt to absorb the light, thus engendering an increase in the rate of photosynthesis.

The first part of photosynthesis requires the absorption of light, and second part does not.\n\nThe light-dependent reactions are those that involve the absorption of a photon of light.   This is the production of the ATP and NADPH.  These take place in the thylakoid part of the chloroplasts of plant cells.\n\nThe light-independent reactions (or the "dark" reactions) do not involve light.  The light-independent part of photosynthesis is the Calvin cycle.  These reactions take place in the fluid (stroma) surrounding the thykaloids.\n\nSee source for more details.

plants hold special bodies called chloroplasts, and within these chloroplasts there are chlorophyll, which absorb all the colours in the spectrum, apart from the colour green, which is why they look green - because the chlorophyll do not absorb green light

simply put: saccarides and oxygen.\nbut there are 2 types of photosynthesis and one works during the day and the other at night and its really complicated. also, one is done in a liquid suspension and the other in these disc-like structures in the chloroplast.

Chloroplasts contain structures called thylakoids.\n\nThe thylakoid membrane contains the two photosystems utilized by photosynthesis. Most simply, when light strikes the reaction centers of the photosystems, electrons are released into an electron transport chain. As electrons move through the chain,  protons are pumped from the stroma of the chloroplast to the lumen (inside) of the thylakoid. Since the thylakoid membrane is impermeable to protons, a gradient is eventually built up within the thylakoid. This gradient powers ATP synthesis.

Green. Carotene sends the light it absorbs on to it's old friend, chlorophyll. Ever see the leaves of carrots?

the people above are wrong the light and dark reactions are names for groups of stages of photosynthesis\n\ntwo actual stages are Kreb's sycle, Calvin's cycles (if you want the last it is electron transport)

chlorophyll is needed in the process of photosynthesis. during the photosynthesis oxigen and glucose are produced. when glucose has to be transported from the leaves to the other parts of plants body it is changed into saccharose (sucrose).\nwhen it reaches for example roots and other parts it is transformed into starch. so it is obvious that in the soil there is no sunlight and in the roots there is no chlorophyll, but the process takes place. chlorophyll and sunlight are not needed.
