What are 2 ways that humans benefit from photosynthesis?

Equally importantly, photosynthesis is the source of oxygen and also removes carbon dioxide from our atmosphere. Oxygen is required for cellular respiration, the process by which food is broken down into energy. Thus, human beings are also solely dependent on photosynthetic plants for their oxygen requirements.

How does photosynthesis affect us?

Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces.

What are the two stages of photosynthesis called?

Photosynthesis in the leaves of plants involves many steps, but it can be divided into two stages: the light-dependent reactions and the Calvin cycle. The light-dependent reactions take place in the thylakoid membrane and require a continuous supply of light energy.

What happens in the two stages of photosynthesis?

Photosynthesis represents the biological process by which plants convert light energy into sugar to fuel plant cells. Comprised of two stages, one stage converts the light energy into sugar, and then cellular respiration converts the sugar to Adenosine triphosphate, known as ATP, the fuel for all cellular life.

Which step of photosynthesis requires carbon dioxide?

The Two Parts of Photosynthesis In the Calvin cycle, which takes place in the stroma, the chemical energy derived from the light-dependent reactions drives both the capture of carbon in carbon dioxide molecules and the subsequent assembly of sugar molecules.

How does photosynthesis work at night?

During the day, photosynthesis is dominant, so there is a net release of oxygen. At night, photosynthesis stops but respiration continues, so there is a net consumption of oxygen. The compensation point is where the net change in oxygen is zero.
