Does a wilted plant go through photosynthesis?
A wilted plant cannot efficiently perform photosynthesis because it lacks turgor pressure for gas exchange and proper functioning of chloroplasts. Photosynthesis requires water for the photolysis of water during the light reactions and as a substrate for the Calvin cycle, both of which are compromised in a wilted plant.
How does photosynthesis and cellular respiration work?
In photosynthesis you get glucose from carbon bi oxide and water. The process takes place step by step. Energy is consumed in this process. In cellular respiration, you get carbon bi oxide and water from the glucose. The process takes place step by step. Energy is released in this process. So it is the game of energy and nothing else. The energy from the sun is trapped and released by plants and animals, respectively. The amount of energy is same photon by photon in both the processes. That is consistent with the conservation of the energy in chemical reactions.
How do Cells perform cellular respiration?
Cellular respiration allows organisms to use (release) energy stored in the chemical bonds of glucose (C6H12O6). The energy in glucose is used to produce ATP. Cells use ATP to supply their energy needs. Cellular respiration is therefore a process in which the energy in glucose is transferred to ATP.
In respiration, glucose is oxidized and thus releases energy. Oxygen is reduced to form water.
The carbon atoms of the sugar molecule are released as carbon dioxide (CO2).
The complete breakdown of glucose to carbon dioxide and water requires two major steps: 1) glycolysis and 2) aerobic respiration. Glycolysis produces two ATP. Thirty-four more ATP are produced by aerobic pathways if oxygen is present.
In the absence of oxygen, fermentation reactions produce alcohol or lactic acid but no additional ATP.
How do the vines on the rain forest floor get the sunlight they need to carry out photosynthesis?
Vines in the rainforest have adaptations that allow them to climb and reach toward gaps in the canopy where sunlight penetrates. They use other plants or structures for support to grow upward and access sunlight for photosynthesis. Vines may also have large leaves that are efficient at capturing sunlight in low-light conditions.
Why do farmers depend on photosynthesis?
photosynthesis is the production of carbohydrates in plants. and carbohydrates and stored in the form of starch and glycogen in plants. this starch and glycogen is actually the fruits and vegetables we eat .so without photosynthesis fruits and vegetables would not be formed and thus farmers would suffer
Does respiration only happen at night for plants?
No, respiration in plants occurs both day and night. During the day, plants undergo both photosynthesis and respiration. Photosynthesis produces glucose and oxygen, while respiration breaks down glucose to release energy for the plant. At night, when there is no sunlight for photosynthesis, plants rely solely on respiration to generate energy.
Can photosynthesis take place in spirogyra?
Yes, photosynthesis can take place in Spirogyra. Spirogyra is a filamentous green algae with chloroplasts that enable it to perform photosynthesis, converting sunlight into energy for growth and survival.
How uv rays affect vegetables?
UV rays can have both positive and negative impacts on vegetables. Moderate exposure to UV rays can increase the production of antioxidants in vegetables, which have health benefits for humans. However, excessive exposure to UV rays can damage the cells of vegetables, leading to reduced growth, changes in appearance, and decreased nutritional value.
Why is photosynthesis essential for all life?
Photosynthesis is important because it produces organic substances, like energy-rich carbohydrates, from simple inorganic ones such as carbon dioxide and water.
All organisms need organic compounds, but only those that perform photosynthesis (autotrophs, or producers) can produce their own. The rest of us (heterotrophs, which includes consumers, decomposers, and saprotrophs) rely on autotrophs for a supply of organic substances.
What organisms use photosynthesis directly?
Plants, algae, and cyanobacteria use photosynthesis directly to convert sunlight into chemical energy in the form of glucose. These organisms contain chlorophyll, a pigment that captures sunlight and drives the photosynthesis process.
What raw materials are needed to manufacture reese cups?
The raw materials needed to manufacture Reese Cups include cocoa beans for chocolate production, sugar for sweetness, peanuts for the filling, and milk for the creamy center. Additional ingredients may include cocoa butter, lecithin, and artificial flavors.
What are the characteristics of light dependent reactions?
Light-dependent reactions occur in the thylakoid membranes of chloroplasts and require light to produce ATP and NADPH, which are used in the Calvin cycle to produce glucose. These reactions involve the conversion of light energy into chemical energy through the processes of photosystem I and photosystem II, as well as the electron transport chain. Oxygen is also produced as a byproduct of these reactions.
What do plants produce that is important to all living things?
Plants produce oxygen during photosynthesis, which is vital for the survival of all living organisms. Oxygen is needed for cellular respiration, a process that releases energy for living organisms to carry out their functions.
Will a plant photosynthesis be faster in a bright light or a dim light?
sunlight is a primary source of nutrients for the plant to make its own food. As it catches more sunlight it is more able to make its food or what you call sugar or another end product, that's what we are using right now, sunlight. Without the sunlight the plant will have a slower growth.
These are called stomata. They are small openings on the surface of plant leaves that allow for gas exchange, including the intake of carbon dioxide for photosynthesis and the release of excess water vapor through transpiration.
What are the application of surface tension in life?
Surface tension is used in many aspects of life, such as in the formation of bubbles in soap and the ability of insects to walk on water. It is also important in medical fields for creating thin films for drug delivery systems and in the food industry for producing emulsions and foams. Additionally, surface tension plays a role in the function of our lungs by helping to keep the alveoli inflated.
Where is the energy stored within chemical coumpounds such as ATP NADPH and glucose?
The energy stored in chemical compounds such as ATP, NADPH, and glucose is stored in the bonds between atoms. When these bonds are broken during chemical reactions, energy is released. This energy can then be used by cells for various metabolic processes.
What energy is required for photosynthesis?
Photosynthesis requires light energy, which is absorbed by pigments in the chloroplasts of plant cells. This light energy is used to convert carbon dioxide and water into glucose and oxygen. Additionally, photosynthesis also requires some chemical energy in the form of ATP and NADPH, which are produced during the light-dependent reactions.
Does E. coli use photosynthesis?
No, E. coli does not use photosynthesis as it is a bacterium that lacks the organelles necessary for this process, such as chloroplasts. Instead, E. coli obtains energy through other metabolic processes like fermentation or aerobic respiration.
Which is role of photosystem in the light reactions?
to make energy-carrier molecules like NADPH
Apex
Where and when does carbon fixation occur in photosynthesis?
in the stomata, prior to the Calvin cycle
How is photosynthesis is related to cellular respiration?
Photosynthesis and cellular respiration are interrelated processes in living organisms. During photosynthesis, plants and some other organisms use sunlight to convert carbon dioxide and water into glucose (a form of stored energy) and oxygen. In contrast, during cellular respiration, organisms break down glucose to produce energy for their cells, releasing carbon dioxide and water as byproducts. These processes are complementary in the carbon cycle, where the products of photosynthesis are used in cellular respiration and vice versa.
What element must be present for both steps of cellular respiration to occur?
Oxygen is the element that must be present for both steps of cellular respiration to occur. It acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP through oxidative phosphorylation.
Why do photosynthesis takes place in desert plants?
Photosynthesis in desert plants occurs during the daytime when temperatures are higher and water availability is lower. These plants have adaptations like CAM or C4 pathways that allow them to conserve water by opening their stomata at night and storing CO2 for use during the day, when photosynthesis takes place. This strategy helps desert plants survive in arid environments with limited water resources.
Factors that slow down the rate of photosynthesis are sunlight and warm temperatures?
Actually, sunlight and warm temperatures are essential for photosynthesis to occur efficiently. Factors like low light intensity, extreme temperatures, insufficient water, and lack of carbon dioxide availability can slow down the rate of photosynthesis.
