Photosynthesis

This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

What is the source of Energy for All Of The Processes that Occur on the Earth's surface?

The primary source of energy for all processes that occur on Earth's surface is the Sun. Solar energy drives weather patterns, plant photosynthesis, ocean currents, and the water cycle, among other vital processes that sustain life on our planet.

Does the process of photosynthesis occur during the winter?

Yes, photosynthesis can still occur during the winter, but at a slower rate due to decreased sunlight and colder temperatures. Evergreen plants, which retain their leaves throughout the year, can continue photosynthesizing during the winter. However, deciduous plants may shed their leaves and enter a dormant state until conditions become more favorable for photosynthesis.

Where does photosynthesis happen in a plant cell?

Photosynthesis happens in the chloroplasts of plant cells. This process uses sunlight to convert carbon dioxide and water into glucose and oxygen.

Can energy in glucose be released by cellular respiration?

Yes, energy in glucose is released by cellular respiration through a series of chemical reactions that break down glucose and convert it into ATP, the cell's main energy source. This process occurs in the mitochondria of cells.

Why does the rate of photosynthesis increase with increasing light intensity?

It increases when temperatures rise and in the winter when it gets cold it decreases and that is to protect the tree or plant. When the day is starting, it increses then peaks in the middle of the day, and then decreases at the end. Temperature determines how much light is givin to the plant.

What is the substance used to make energy for photosynthesis?

The substance used to make energy for photosynthesis is sunlight. Plants use light energy to convert carbon dioxide and water into glucose, a form of chemical energy that can be used by the plant for growth and development.

How is the equation for respiration related to the photosynthesis equation?

They both use the same things but photosynthesis's products are what respiration starts with like respirtion needs oxgyen and glucose or sugar and photosynthesis is what give the oxgyen and glucose (sugar).

Organelles in plant cells that function in photosynthesis or storage are called?

Organelles in plant cells that function in photosynthesis or storage are called chloroplasts. Chloroplasts allow plants to capture the energy of the sun. Vacuoles are involved in storage of soluble carbohydrates or proteins.

What is the word and symbol for photosynthesis?

The word Equation is Carbon dioxide+water---->glucose+oxygen and the symboly eqation is 6CO2 + 6H2O ---> C6H12O6 + 6O2

What does photosynthesis create?

Photosynthesis produces glucose (C6H12O6) which is required by organisms for respiration, it also gives off bi-products of O2 and water, the oxygen is released into the atmosphere or recycled by the plant in its own respiration reactions.

What are the parts of photosynthesis?

Photosynthesis consists of two main parts: the light-dependent reactions, which occur in the thylakoid membranes of chloroplasts and require sunlight to produce ATP and NADPH, and the light-independent reactions (Calvin cycle), which take place in the stroma of chloroplasts and use ATP and NADPH to convert carbon dioxide into glucose.

What are the waste products in photosynthesis?

The waste product of photosynthesis is oxygen, which is released into the atmosphere as a byproduct of the light-dependent reactions. This oxygen is crucial for many organisms, including humans, as it is essential for respiration.

What is reversible formula for photosynthesis and respiration?

Photosynthesis Needs light energy, co2, and h2o. It gives off Glucose and o2. Respiration needs o2 and glucose. It gives of energy, o2, and h2o.

What are the clusters of photosystems?

The two clusters of photosystems in plants are Photosystem I (PSI) and Photosystem II (PSII). PSII functions first in the photosynthetic electron transport chain, followed by PSI, and they work together to absorb light energy and carry out the reactions of photosynthesis.

What is produced by the light reaction of photosynthesis?

The light reaction of photosynthesis produces ATP (adenosine triphosphate), NADPH, and oxygen. ATP and NADPH provide the energy and reducing power needed for the Calvin cycle (dark reactions) to produce sugar molecules.

Where is the site of the photosystems in the light-dependent reactions of photosynthesis?

The photosystems in the light-dependent reactions of photosynthesis are located in the thylakoid membranes of the chloroplast. Photosystem I and Photosystem II are embedded in the thylakoid membrane and are responsible for capturing and converting light energy into chemical energy.

Name the organelle in which photosynthesis occurs?

The organelle in which photosynthesis takes place is the chloroplast.

Chloroplast is the photosynthesizing organelle in eukaiyotes. In prokariyotes,it takes place in photosynthetic filaments

What happens to the water molecules when the plants absorb light energy during photosynthesis?

Water molecules are split into oxygen, protons, and electrons when plants absorb light energy during photosynthesis. This process is known as photolysis and occurs in the thylakoid membranes of the chloroplasts. Oxygen is released as a byproduct, while the protons and electrons are used to produce ATP and NADPH for the Calvin cycle.

What is the source of engery for the photosynthesis reactions and where do they take place in a cell?

The energy for photosynthesis reactions comes from sunlight. These reactions take place in the chloroplasts of plant cells, specifically in the thylakoid membrane where pigments like chlorophyll capture light energy to drive the process of photosynthesis.

What is released after photosynthesis?

The primary products released after photosynthesis are oxygen and glucose. Oxygen is released as a byproduct of the light-dependent reactions, while glucose is formed as a result of the light-independent reactions.

How does photosynthesis in plants benefits animals?

Photosynthesis in plants converts energy from the sun into a chemical that animals are in turn able to consume and convert back into the energy they require to function. Photosynthesis also converts the poisonous gas CO2 back into its components, Carbon and oxygen. Both of these processes are imperative for animals to survive as they have no way of directly accessing the suns energy nor are they able to cope with high concentrations of carbon dioxide or the effects that this gas has in the atmosphere.

Plant tissue noted for photosynthesis storage and secretion is?

The plant tissue noted for photosynthesis is the mesophyll tissue, specifically the palisade mesophyll layer. The storage tissue is the parenchyma cells that store starch, water, and nutrients. The secretion tissue is the glandular tissue such as the secretory hairs or glands found in certain plants.

Plant cells undergo photosynthesis Which organelle does this process take place in?

Photosynthesis takes place in the chloroplasts of plant cells. Within the chloroplasts, the pigment chlorophyll captures sunlight and converts it into chemical energy to produce glucose from carbon dioxide and water.

What powers the proton gradient of positive ions in the stroma?

The proton gradient across the thylakoid membrane is powered by the flow of electrons from water to NADP+ during photosynthesis. This flow of electrons creates a proton gradient that drives ATP production through ATP synthase.
