How would you define photosynthesis?

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. 5 – 8. Biology.

What are the two systems of photosynthesis?

The stages of photosynthesis There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

What did Joseph Priestley discover about photosynthesis?

Joseph Priestly Several centuries later, Joseph Priestley (1733 – 1804) carried out an experiment that showed that plants produce oxygen. He put a mint plant in a closed container with a burning candle. The candle flame used up the oxygen and went out.

What is the main photosynthetic system?

Plants are the most common autotrophs in terrestrial—land—ecosystems. All green plant tissues can photosynthesize, but in most plants, but the majority of photosynthesis usually takes place in the leaves. The cells in a middle layer of leaf tissue called the mesophyll are the primary site of photosynthesis.

What is photosynthesis Wikipedia?

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism’s activities.

How was photosynthesis discovered?

Photosynthesis was partially discovered in the 1600’s by Jan Baptista van Helmont, a Belgian chemist, physiologist and physician. Helmont performed a 5-year experiment involving a willow tree which he planted in a pot with soil and placed in a controlled environment.

Where is photosynthesis occur?

chloroplasts
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
