Which part of the plant cell absorbs the energy from the sun and uses it in photosynthesis?
Chloroplasts are responsible for absorbing sunlight and converting it into energy through the process of photosynthesis in plant cells. Within the chloroplasts, the pigment chlorophyll captures the sunlight and initiates the chemical reactions needed for photosynthesis to occur.
What equation best describes photosynthesis?
The overall equation for photosynthesis is: 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2. This summarizes the process where carbon dioxide, water, and light energy are converted into glucose and oxygen by plants.
What are the 2 main reactions in photosynthesis?
Photosynthesis happens in two stages, also called reactions. The first stage is the light-dependent stage. In this stage light energy is absorbed by chlorophyll and converted into chemical energy, and water is split to produce hydrogen. The unwanted oxygen from the water is released. The second stage is the light-independent stage. In this stage the chemical energy and the hydrogen from the first stage are used to convert carbon dioxide into carbohydrates, such as glucose. More details can be found on this site by searching for photosynthesis.
Wood is a hard, fibrous structural tissue found in the stems and roots of trees and other woody plants. It is primarily composed of cellulose, hemicellulose, and lignin, and serves as a support system for the plant while also conducting water and nutrients.
What substances does photosynthesis produce?
Photosynthesis produces glucose, which is a type of sugar that serves as the main source of energy for plants and other organisms. Additionally, during the process, oxygen is released as a byproduct into the atmosphere.
Is photosynthesis performed by all plants?
All plants that HAVE CHLOROPHYLL. Most plants that have chlorophyll are green.
Photosynthesis is when H20 and C02 is taken in from a plant and using the energy of the sun, turn it into glucose (C6 H12 O6), which is used as food in plants.
Most of the photosynthesis occurring in the plant happens in the leaves. When glucose is created, then phloem (vascular tissue located in the stem) carries it to other places in the plant, thus powering the whole plant.
G3P is a three-carbon molecule that serves as a critical intermediate in the Calvin cycle. It is used to generate glucose and other carbohydrates that plants need for growth and metabolism. The production of G3P is essential for converting carbon dioxide into organic compounds that fuel plant growth.
Does the Calvin cycle release or absorb energy?
The Calvin cycle absorbs energy in the form of ATP and NADPH in order to convert carbon dioxide into glucose.
Light absorbing pigment in plants and some protists that is required for photosynthesis?
Chlorophyll is the light-absorbing pigment in plants and some protists that is essential for photosynthesis. It absorbs sunlight and converts it into chemical energy that is used to produce sugars from carbon dioxide and water. Without chlorophyll, the process of photosynthesis cannot occur.
What substance needed for photosynthesis does the tree take from the soil?
The tree takes up water and minerals from the soil, which are essential for photosynthesis to occur. Water and minerals are absorbed through the tree's roots and transported to the leaves where photosynthesis takes place.
What vegetables store their food in stem?
Some vegetables that store their food in their stems include kohlrabi, rhubarb, and asparagus. These vegetables rely on their stem structures to store nutrients and energy for growth and reproduction.
In photosynthesis what waste products are produced?
In photosynthesis, the waste product produced is oxygen. Oxygen is released as a byproduct when plants and other photosynthetic organisms use sunlight to convert carbon dioxide and water into glucose and oxygen.
What is palisades job in photosynthesis?
Palisade cells in plant leaves are responsible for photosynthesis. They contain many chloroplasts, where photosynthesis occurs, and are packed with chlorophyll pigments that capture light energy. This energy is then used to convert carbon dioxide and water into glucose, a form of energy that plants can use.
What are 2 energy sources created in the light reactions?
The two energy sources created in the light reactions of photosynthesis are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules carry energy that can be used in the Calvin cycle to produce carbohydrates.
What was the earth's atmosphere before like photosynthesis?
Before photosynthesis, the Earth's atmosphere was primarily composed of carbon dioxide and nitrogen, with very little oxygen. The emergence of photosynthetic organisms led to an increase in atmospheric oxygen levels over time.
Where does the xylem get water?
The xylem gets water from the roots of the plant through the process of transpiration and root pressure. Water is absorbed by the plant's roots from the soil and transported through the xylem tissues to the rest of the plant.
Can ATP be directly derived from sunlight?
No, ATP cannot be directly derived from sunlight. ATP is produced through cellular respiration, a process that converts energy stored in glucose into ATP. Sunlight is required for photosynthesis, which produces glucose through the conversion of sunlight, water, and carbon dioxide.
What is the role of carbon dioxide in photosynthesis and cellular respiration?
The role of carbon dioxide in photosynthesis is in the creation of molecules that are used to make food for the plants. In cellular respiration, carbon dioxide is emitted as a waste product that is used by photosynthesizing cells to create new carbohydrates.
What three tings do plants need for photosynthesis?
Plants need sunlight, water, and carbon dioxide for photosynthesis. Sunlight provides the energy needed to drive the process, water is essential for transporting nutrients and maintaining cell structure, and carbon dioxide is the source of carbon atoms for building sugars.
In which organism would you find chlorophyll?
All the autotrophic organisms (organism which has ability to manufacture its own food) have chlorophyll.
What absorbs the light used to drive photosynthesis?
Chlorophyll, a pigment found in the chloroplasts of plants, absorbs light energy used in photosynthesis. The main pigments responsible for capturing light are chlorophyll a and chlorophyll b, which absorb blue and red wavelengths of light.
How is energy transferred during photosynthesis?
During photosynthesis, energy from sunlight is absorbed by chlorophyll in plant cells. This energy is then used to convert carbon dioxide and water into glucose and oxygen through a series of chemical reactions. The glucose produced serves as a source of energy for the plant, while oxygen is released as a byproduct.
Plants convert sunlight energy into what?
Plants convert sunlight energy into chemical energy through the process of photosynthesis. This chemical energy is stored in the form of carbohydrates like glucose, which the plant uses for growth, reproduction, and maintenance.
