Plant photosynthesis happens in leaves and stems with green stem with a special organelle called a chloroplast. A plant leaf has tens of thousands of cells, and they contain 40-50 chloroplasts. The chloroplast, is an oval-shaped structure, and is divided by membranes into numerous disk-shaped compartments. The disk like compartments, which are called thylakoids, are placed vertically in the chloroplast and look like a stack of plates or pancakes. One stack of thylakoids is called a granum or more than one grana, the grana lie placed in a fluid known as the stroma. Inside of the thylakoids are hundreds of molecules of chlorophyll, which is a light capturing pigment used for photosynthesis. More light trapping pigments, like enzymes used to speed up chemical reactions, as well as other molecules used for photosynthesis and in the thylakoid membrane. These pigments and enzymes are put into two types of units, Photosystem I and Photosystem II. A chloroplast may have dozens of thylakoids, and each thylakoid may contain thousands of photosystems, each chloroplast will have millions of pigment molecules.
Photosynthesis is an intricate process, and because it is so long, plant biologists separate it into two stages. The first stage is the light dependent reaction(it was called the light reaction), and the chloroplast traps light energy and changes it into chemical energy which is (NADPH) and (ATP), these are two molecules used in the second stage of photosynthesis. In the second stage, this is called the light-independent reaction (it was called the dark reaction), NADPH gives the hydrogen atoms to help form glucose, and ATP gives the energy for reactions used to make glucose. The stages are literal meaning of photosynthesis, to build ...

...he light-independent reaction starts in the stroma when the carbon dioxide molecules bind with sugar molecules called (RuBP) in a process known as carbon fixation.
With help of enzymes, six molecules of carbon dioxide connect to six molecules of (RuBP) to create six new molecules. More steps need (ATP), (NADPH), and more enzymes, rearrange the position of the carbon, hydrogen, and oxygen atoms in these six molecules, and when the reactions are done, a new molecule of glucose has been made and five molecules of RuBP have been made. Thsi process happens more than once in each chloroplast while carbon dioxide, (ATP), and (NADPH) are available. The thousands of glucose molecules produced in this reaction are processed by the plant to make energy and is known as aerobic respiration, used as structural materials or stored. The new (RuBP) starts the cycle all over again.

A Study On Plant Tissues, Organ System, And How They Affect The Environment

- his semester intrigued my curiosity about plants , and how are they seen in this modern society. Nowadays plants are not seeing as a priority like back in the days. Before the industrialization the agricultures was one of the primary money maker. Nowadays what has being making money and being important to society has being the different innovations in technology. Plants have being gradually forgotten in the past couple of centuries (industrialization 1800s) . As a biology major, this semester I had the experience to study the plant tissues, organ system, and how they affect the environment....   [tags: Plant, Photosynthesis, Organism, Oxygen]

The Effect Of Carbon Dioxide On The Production Of Glucose Molecules During Photosynthesis

- Carbon dioxide is a reactant in the production of glucose molecules during photosynthesis, and is therefore a limiting factor of the rate of photosynthesis. It is taken in through the stomata in the leaves of plants and reacts with light and water to form oxygen gas and organic molecules. Respiration uses the organic molecules and oxygen gas to form carbon dioxide, water, and energy in the form of ATP. This energy is then used by the plant for growth and metabolic functions, making this process essential to life (Benniston and Harriman 2008)....   [tags: Carbon dioxide, Photosynthesis, Oxygen, Plant]

The Plant World Essay

- Introduction Plants exhibit exceptionally intelligent behaviour when it comes to interactions with their environment. They can detect perceived threats, then convey warning signals to other plants via chemical signaling. Forewarned plants will then assemble their defenses against these potential threats, thus, increasing their chance of survival and reproduction. Communication and competition are common occurrences among the plant world. Another brilliantly, almost inconceivable capability plants possess is the ability to recognize coexisting family members within their home range....   [tags: Environment, Plant Species, Plant Communication]

Essay on Salt Stress Affects The Growth Of The Plant

- The obtained results proved that salt stress can affect overall growth of the plant, either weight or length. The shoot as well as root weight decreased under salinity. In this cultivar, root fresh and also dry weights were more affected than those of the shoot. These findings were in agreement of some previous studies, (for example, Khan et al 2013, Munns 2002; Maas and Grattan 1999). The result of these studies showed that a decrease in plants overall growth due to decrement in weight of dry root and shoot, and stem elongation....   [tags: Plant, Photosynthesis, Sodium, Sodium chloride]

Effects of CO2 Concentration on the Rate of Photosynthesis Essay

- Effects of CO2 Concentration on the Rate of Photosynthesis Whenever there is an increase of CO2 in the atmosphere, plants respond by reducing stomatal conductances, hence, water loss is reduced. This result in greater soil moisture content in ecosystems rich with CO2, this increases plant growth In a review of studies conducted over the prior decade, Pospisilova and Catsky (1999) compiled over 150 individual plant water use responses to atmospheric CO2 enrichment. They found that elevated CO2 increased rates of net photosynthesis in about 85% of the reported studies, while reducing stomatal conductances and rates of transpiration in approximately 75% of the cases analyzed....   [tags: transpiration, environment, ecosystems]

Animal Cells Vs. Plant Cells Essays

- Animal Cells vs. Plant Cells Introduction Cells are the basic units of life, and they can be found everywhere that you look and go. Most cells cannot be viewed without the aid of a microscope. Plant and animal cells are very different not only in their structure shape but in their functions as well. The diagrams found in the book on pages 65-66 are described as generalized cells that are used for study purposes (Mader & Windelspecht, 2016). According to Carl Woese, a professor of microbiology at the University of Illinois, eukaryote cells are more structurally complex than those of their prokaryotic counterparts....   [tags: Eukaryote, Cell, Organelle, Bacteria]
