Can there be photosynthesis without oxygen?

Can there be photosynthesis without oxygen?

Plants, algae, and cyanobacteria perform photosynthesis with the resultant production of oxygen, which supports all organisms that consume it through their respiration. However, another type of photochemical reaction, photosynthesis without oxygen production, exists, and has been designated anoxygenic photosynthesis.

What would happen to photosynthesis without oxygen?

Without photosynthesis there would be no supply of oxygen and slowly the oxygen would get used up by oxidation such as rust formation. Furthermore, by removing plants, all of the many many animals that depend on plants would get very very hungry and gradually die.

Does not using oxygen produce energy?

anaerobic cell
In the case of the anaerobic cell, they acquire energy from the process of metabolism in the absence of energy. For example, yeast is the cells which do not require oxygen for producing energy, they simply convert the sugar into alcohol and release energy.

Where does photosynthesis get the energy that it needs?

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

What happens when a plant has no oxygen?

Respiration is when plants absorb light (photosynthesis), and convert it with water, and carbon dioxide into food (like starch and glucose). The stomata (tiny pores) on leaves expel the extra, unneeded stuff (like water vapor and oxygen) into the air. Without oxygen, plants cannot respire.

Is chlorophyll necessary for photosynthesis?

The role of chlorophyll in photosynthesis is vital. Chlorophyll, which resides in the chloroplasts of plants, is the green pigment that is necessary in order for plants to convert carbon dioxide and water, using sunlight, into oxygen and glucose.

Do plants need oxygen to make energy Why or why not?

Plants need oxygen to survive, and plant cells are constantly using oxygen. The reason is that plants respire, too, just like animals. Respiration doesn’t just mean “breathing.” It is a process that all living things use to release energy for use in their cells.

What happens to a plant without oxygen?

Where does the energy for photosynthesis come from?

By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2). CREDIT: mapichai/Shutterstock.com

How does a herbivore obtain energy during photosynthesis?

Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores. During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons.

What happens to carbon dioxide and water during photosynthesis?

The process During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

What are the three things needed for photosynthesis?

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).
