Photosynthesis is performed by various life forms, however, the best organisms’ for this process is by cyanobacteria, algae and higher plants (Vermaas, 2013). The end result of the Photosynthesis process is the storage of energy in sugar bonds. Vegetation requires energy, H2O and CO2 in order to create sugar. Photosynthesis occurs in a plant’s chloroplasts, specifically using the green pigment that captures light energy; which is why it primarily takes place in the plant’s leaves. The veins in a leaf transport nutrients and water where they are needed and chloroplasts are in a plant’s mesophyll cells, which is where photosynthesis takes place.
Plant Structure. LEAVES: · Leaves are the plant organs where most photosynthesis occurs. Their broad flattened structure optimizes the surface area exposed to light. Plant morphologists have developed a hypothesis, supported by scientific evidence, that leaves are flattened stems between which tissue has developed. · The shape and structure of leaves vary considerably from species to species of plant, depending largely on their adaptation to climate and available light, but also to other factors such as grazing animals, available nutrients, and ecological competition from other plants.
What kind of animal is Vulpes velox? How do you know? Use Table 17-1. 20. Classify each of the items in below as a bacterium, protist, or fungus.
Section C. Question: Discuss the chemical process of photosynthesis in plants. Explain in detail the uptake of raw materials, the light and dark stages and the formation of products? What is photosynthesis? 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).
You can also clearly see the sepals on the new buds. The African violet can be propagated by placing a whole leaf in soil covering the leaf only about one third of the way up. Once planted treat it the same as the parent plant by keeping it watered and in indirect sunlight. Works Cited "African violet". Encyclopædia Britannica.
The process of photosynthesis is when plants use the energy in sunlight to convert water and carbon dioxide into oxygen and high-energy carbohydrates. Photosynthesis occurs inside a cell organelle called the chloroplast. The chloroplast contains green pigments called chlorophyll, which capture the energy in sunlight. The equation for photosynthesis is as follows: Light 6CO2 + 6H2O à C6H12O6 + 6O2 (Moran 2006) The raw materials needed for photosynthesis are carbon dioxide from the air (taken in through the leaves) and water, usually from the soil (taken in through the roots). The two combine initially to produce simple sugars and oxygen.
Blanca Mbuto 02/19/2012 Biochemistry Lab 4422 Cell Fractionation by Centrifugation Abstract This experiment was performed to investigate organelles, membranes, cellular components, and enzymes. Our concentration was to observe and determine if the chlorophyll contained broken chloroplasts or intact chloroplasts extracted from spinach leaves. A percoll density gradient was prepared followed by the separation of organelles. Chlorophyll was analyzed by using a spectrophotometer. We compared the absorbance readings of each tube and selected three (3) tubes to be analyzed.
There are many different photosynthetic pigments in each of these that play a part in photosynthesis, but the most common pigments are chlorophyll “a” & “b”, phycocyanin, phycoerythrin and the carotenoids. Chlorophyll “a” is a green pigment that is found in all plants, most algae, and in cyanobacteria (Speer). It is located inside the cell’s chloroplast and embedded in the thylakoid membranes, where photosystem I and II are (Chlorophylls a and b). This pigment is the most common chlorophyll pigment, and also the most important pigment out of all the other photosynthetic pigments. It is the only pigment that is used in the very core of the photosystems.
