Chloroplast

a. The structures of chloroplasts overall assist with the contribution of the function of photosynthesis. The thylakoid membrane is an essential structure to chloroplasts because it allows the process of light reactions to take place. Photosystem l, makes NADPH from chlorophyll and is responsible for the transfer of electrons with high energy levels to additional molecules. Whereas, photosystem II produces ATP with the usage of an electron from light. Moreover, the thylakoid space is beneficial for the function of photosynthesis due to the reason being that it helps generate the concentration gradient of protons and absorb light in photosynthesis. Furthermore, the stroma structure plays a significant factor in the function of the action of the process. During photosynthesis, the stroma is accountable for the synthesis of molecules from carbon dioxide and water to form a carbohydrate molecule. Each individual structure of chloroplast is imperative to the process of photosynthesis. b. There are vital steps for light dependent reactions that take place in the thylakoid membrane. The overall function of the process is to convert light energy to make both NADPH…

The Effect of Different Colored Lights on Photosynthesis My group studied the effect of light on photosynthesis in our experiment. Photosynthesis occurs in the chloroplast of the cell. Photosynthesis happens when water is absorbed by the roots of green plants and is carried to the leaves by the xylem, and carbon dioxide is obtained from air that enters the leaves through the stomata and diffuses to the cells that have chlorophyll. In our experiment we tested how different colored lights would…

into chemical energy or food. leaves have a flat base which allows them to absorb more light. they have a very thin layer which allows carbon dioxide in and oxygen to diffuse out easily. chlorophyl plays a large role in photosynthesis this gives the leave its green colour and transfers light energy into chemical energy or food. The veins that can be seen along the leaf transport substances to and from the cells of the leaf. there are several differant layers of a leaf. The waterproof cuticle…

The Endosybiant theory states that the mitochondria and the chloroplasts were at one point in evolution, prokaryotic cells. It is said that before they had the function and job that they have today, that the mitochondria and the chloroplasts lived on their own and commonly took shelter inside of larger host cells. There they provided the host cell with the nutrients that it needed to live, and in return the host cell gave the cells a protected place to live. Eventually the host cell, the…

Article 1: Scientists unravel the colorful sea slug's solar-energy theory 1) Why are chloroplasts important for plants? Chloroplasts are important for plants because they contain Chlorophyll, used in photosynthesis. The Chlorophyll is what made it possible for plants to absorb and process the sun's energy and combine it with carbon dioxide and water to grow and make food. Photosynthesis also releases oxygen for humans to breath. 2) List two reasons and explain why the chloroplasts were helpful…

Light dependent reactions occur in the thylakoid membrane of the chloroplasts and take place only when light is available. During these reactions light energy is converted to chemical energy. Chlorophyll and other pigments absorb energy from sunlight. This energy is transferred to the photosystems responsible for photosynthesis. Water is used to provide electrons and hydrogen ions but also produces oxygen. The electrons and hydrogen ions are used to create ATP and NADPH. ATP is an energy storage…

Active and passive transport move oxygen, water, and nutrients into cells and remove waste. Active transport requires a chemical energy because it moves from lower concentration to areas of higher concentration. It uses ATP to pump the molecules against the concentration, which requires cellular of solute. Passive transport moves from areas at a higher concentration to low concentrations, so it doesn’t require energy. Active transport takes place in the membranes of both the mitochondria and…

the colonization of terrestrial ecosystems. Ever since late Silurian (425 Ma), land plants have been competing, evolving and diverging to give rise to new species, while nearly all plant species that existed up until 10kya have gone extinct and there is an estimated 400,000 plant species in present day (Chapman 2009). All plants require water, sunlight, nutrients, and territory for their survival. Water and sunlight are required for photosynthesis, the process of creating energy for organismal…

There are key differences between cellular respiration and photosynthesis that can help one learn about each process on a deeper level. Cellular respiration’s goal is to break down certain food molecules like sugars, fats, and carbohydrates and convert it to ATP or energy for the cell to use. For photosynthesis, its purpose is to obtain solar energy and convert that energy into chemical energy and glucose for food and an energy storage. Cellular respiration occurs in the mitochondria, which is…

Photosynthesis is the process by which plants and other organisms create energy. Light energy is converted into chemical energy that can be stored and used. CO2, water and light are converted into glucose and oxygen. The general chemical formula for this is, CO2 + H2O + light energy → Glucose + O2. In this experiment, we will test the relationship between the rate of photosynthesis and the water consumed by the plant; we will be testing tap water–for a control, sugar water and salt water. If we…
