What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in chloroplasts that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What are autotrophs?

Back

Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis, such as plants and some bacteria.

Front

What is the stroma in a chloroplast?

Back

The stroma is the fluid-filled interior space of the chloroplast where the light-independent reactions (Calvin cycle) of photosynthesis occur.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

Front

What is the light-dependent reaction?

Back

The light-dependent reaction is the first stage of photosynthesis that occurs in the thylakoids, where light energy is converted into chemical energy (ATP and NADPH).

Front

What is the light-independent reaction (Calvin cycle)?

Back

The light-independent reaction, also known as the Calvin cycle, occurs in the stroma and uses ATP and NADPH to convert carbon dioxide into glucose.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes, including those in photosynthesis.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons for the light-dependent reactions and is split to release oxygen.
