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.

6,415 Questions

Is photosynthesis a herbivore or a carnivore?

Neither. Herbivores and carnivores are classifications of animals based on what they eat. Photosynthesis is a process carried out by plants and algae.

Why do you think guard cells are called such?

Guard cells are named for their role in regulating the opening and closing of stomata, which are small pores on the surface of plant leaves. By changing shape to control the size of the stomatal pore, guard cells help regulate gas exchange and water loss in plants.

What happens to the sugar plants make?

They are broken down in respiration. Energy is obtained by that

What is the wavelength of solar energy used for photosynthesis?

680 nanometers to 700 nanometers is about optimum for the photosynthetic rate but there are other wave lengths that plants do use.

Losing excessive amounts of water through evaporation may effect a plant's ability to carry out photosynthesis true or false?

True. Excessive water loss through evaporation can cause dehydration in a plant, leading to wilting and reduced turgor pressure in the cells. This can hinder the plant's ability to take in carbon dioxide for photosynthesis, as stomata may close to conserve water.

How is gas released during photosynthesis?

During photosynthesis, gas is released as a byproduct of the light-dependent reactions. Oxygen is produced when water molecules are split and their electrons are transferred through the electron transport chain in the thylakoid membranes of chloroplasts. This oxygen is then released into the atmosphere as a waste product of photosynthesis.

How are photosynthesis and cellular respiration cellular?

Photosynthesis and cellular respiration are both cellular processes that occur in the cells of organisms. Photosynthesis is the process by which plants and some bacteria convert sunlight, water, and carbon dioxide into glucose and oxygen. Cellular respiration is the process by which cells break down glucose and oxygen to produce energy, carbon dioxide, and water. Both processes are vital for the survival of organisms, as they provide energy and regulate the levels of oxygen and carbon dioxide in the atmosphere.

How many carbon dioxide molecules are needed to make a single molecule?

None. You see, carbon dioxide, per say, is not used in the chemical formula for glusose, which is C6-H12-O6. It makes use of six carbon atoms and six oxygen atoms, but no carbon dioxide moleecules.

Which is a reactanct for the photosynthesis reaction?

Reactants for photosynthesis are:

  • Water
  • Oxygen
  • Sugars
  • Carbon Dioxide
  • Light

How is cellular respiration similar to photosynthesis?

Photosynthesis and cellular respiration are both cellular processes organisms use to obtain energy.

What are the inputsoutputs of a cell?

Cellular Respiration Relationship In plants, plants use the outputs of photosynthesis (sugar, oxygen) as the inputs of cellular respiration. They then use the outputs of cellular respiration as the inputs of photosynthesis. It is a cycle.

What part of speech is the word photosynthesis?

Photosynthesis is a noun. It describes the process by which carbohydrates, carbon dioxide, water, and salts, are converted using sunlight as energy.

Why is the process of photosynthesis essential infood chain?

Life is powered by sunlight. The energy used by most living cells comes ultimately from the sun. Plants, algae, and some bacteria use energy from sunlight, particularly blue and red wavelengths, to build molecules which later can be split through cellular respiration to retrieve some of that energy. Storing energy in molecules and then oxidizing those molecules to retrieve the stored energy maintains all life on Earth. Plants are often called ‘producers’ because they produce energy-storing molecules used by almost all other organisms on Earth. By eating plants, herbivores ‘steal’ these energy-storing molecules to maintain their own life processes. By eating animals, carnivores ‘plunder’ the molecules that store the energy oringinally captured by plants. By feeding on dead tissue, decomposers exploit whatever molecules remain in the dead the plants, herbivores, and carnivores. Ultimately, the process of photosynthesis is the most important chemical reaction on Earth.

Is carbon dioxide used or produced during photosynthesis?

During photosynthesis, carbon dioxide is used by plants to produce glucose. The carbon dioxide is taken in through the stomata on the leaves and is converted into glucose with the help of sunlight, water, and chlorophyll.

The stractures in most seed plants where the food making process in which it occurs?

The food-making process in seed plants, called photosynthesis, occurs in specialized structures called chloroplasts. Chloroplasts are primarily found in the green tissues of plants, such as leaves, where they capture sunlight and convert it into energy to produce glucose. This glucose is then used as food by the plant for growth and development.

How do plants photosynthesize in adverse conditions?

There are a variety of conditions which are adverse to photosynthesis, such as dim lighting, lack of water, etc. In adverse conditions, photosynthesis is either slowed down or ceases entirely. But to the extent that photosynthesis may continue to take place, it happens in the usual way; there is just less of it.

Is photosynthesis only possible in the leaves?

Any psrt of the plant that is green. Some plants have chlorophyll in the stems as well.

What is the greenhouse gas in the photosynthesis reaction?

The greenhouse gas in the photosynthesis reaction is carbon dioxide (CO2). During photosynthesis, plants use sunlight to convert carbon dioxide into glucose and oxygen, thus reducing the amount of CO2 in the atmosphere.
