Introduction:
Photosynthesis is a process used by plants and specific types of bacteria in order to make their own food source from sunlight to chemical energy. It is mainly occurred within the leaves of the plant. The reaction requires light energy in order for it to be absorbed by chlorophyll. During the reaction carbon dioxide, water is converted into glucose and oxygen as shown below:

There are two types of photosynthetic processes; one includes oxygenic photosynthesis, which is most common and demonstrated through plants, algae and cyanobacteria while the other one is an-oxygenic photosynthesis. (From Light Energy to Chemical Energy, Accessed 08 March 2018). Products to are made through photosynthesis as glucose is transported in to the plant as soluble sugars and stored as starch which is insoluble hence it is unable to escape from the cell. Although starch is able to revert back into glucose in order to release energy by respiration both useful for fats and oils for storage through the plant, proteins for growth and repair and cellulose for their cell walls.

Chlorophyll is an essential need to photosynthesis as it is able to trap both blue and red light. It is a complex molecule consisting of three sub types;
Lima bean number 1 germinated but did not thrive. My plant was a yellow color with few leaves. Though my plant was very tall it was weak and could be broken easily. The plants in uv light were of a dark green color whereas my plant was yellow. In addition the leaves of my plant were very small.

Light-Dependent Reaction :
The energy releasing, light-dependent reactions of photosynthesis turn light energy into chemical energy. Which transfers this energy to ATP and NADPH, this then happens in the stacks of thylakoids of chloroplasts. ATP and NADPH are needed for the energy that is used in the light-dependent reaction.
Photosynthesis takes place in the chloroplasts; green organelles inside plant cells. The thylakoid inside Chloroplasts absorb the sunlight energy needed for photosynthesis. The pigment in the thylakoid absorbs light; however, plants reflect green light. This gives plants their color. If different colors of light are shown on spinach leaves and CO2 consumption is measured, then the spinach leaves given green light will consume the least amount of CO2 due to reduced photosynthesis activity.

Answer the following questions as completely and concisely as possible. Some answers may be a single word, but for more detailed responses, keep you answer to 3 sentences or less.
What is the electron donor of an organism growing chemorganotrophically?
The electron donor of an organism growing chemorganotrophically is an organic compound such as glucose, acetate, etc.
All organisms use food molecules, like glucose to produce ATP. The production of ATP occurs during cellular respiration. ATP provides the cells with energy that is necessary to produce oxygen. The seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide.
Photosynthesis consists of two stages, the light reactions and the dark reactions.
The light reactions convert light into energy (ATP and NADHP)
Occurs in thylakoid stacks of grana
Sunlight is converted into ATP (free energy containing molecule) and NADPH (high energy electron carrying molecule)
Chlorophyll absorbs light energy and starts a chain of
The process of photosynthesis is vital for the survival of most life on Earth. Without photosynthesis plant life would be unable to create its own food and sustain themselves causing them to die. Earth would lack the oxygen and energy that plant life provides. Producers are the main source of energy for living organisms because they can directly absorb light energy and turn it into chemical energy. Animals then eat the plants which give them a portion of that energy.
Photosynthesis and cellular respiration are processes that help human beings live. The reactants in photosynthesis are carbon dioxide, water, and the sunlight’s energy. The products of these reactants are glucose and oxygen. Photosynthesis takes place in the chloroplasts in only plant cells. This is when plants convert carbon dioxide and water into glucose by using the sun’s energy.
photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.
Therefore the green light is unable to assist in the photosynthesis process, because the majority of the solar energy in the green light is being reflected rather than absorbed by the plant. This results in the reduction of the plant's absorption of solar energy and Co2, which subsequently leads to the decreased release of oxygen, that overall impairs the light reaction within the photosynthesis process.
My claim is photosynthesis does models the Law of Conservation of Matter and Energy because photosynthesis allows plants to store/reuse matter and energy.
My first piece of evidence that supports the law of conservation of energy is when a bird eats a caterpillar then the bird gets the energy from the worm “so the bird indirectly gets the energy that began with glucose.” (Photosynthesis by ck-12 , n.d)
My next piece of evidence is the sun's energy (light energy) is used to make the plants food glucose, which is the plant's energy, this shows the Law of Conservation of Matter because the light energy is transformed into something new which is the plant's food . (photosynthesis , n.d)
it go through how energy transfers from the sun then to the plants and on to the animals. It is more complicated than that but a simple explanation is this. All energy starts from the sun in the form of white light. Then autotrophs being primary producers of an ecosystem through the process of, photosynthesis, turns that sunlight into energy. Then herbivores eat that plant turning the energy in the form of glucose into there own energy through cellular respiration.
A Raisin in the Sun
"Education has spoiled many a good plow hand" (Hansberry 103). This quote is significant because it is applying that education is better than being a hard-worker. A Raisin in the Sun, written by Lorraine Hansberry, is taken place in South Side, Chicago between World War II and the present. The main focus of this play is about a poor African-American family who has a chance to escape this lifestyle with a ten-thousand-dollar life insurance check, but is not desired to live in a "white" neighborhood.
