Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves. The thylakoids sit inside the chloroplast and they contain chlorophyll which absorbs the different colours of the light spectrum to create energy (Source: Biology: LibreTexts).
How does photosynthesis occur?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) 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 steps in photosynthesis and where do they occur in the chloroplast?
The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
What are the 4 main steps of photosynthesis?
The overall process of photosynthesis can be objectively divided into four steps/ process:
- Absorption of light. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts. ...
- Electron Transfer. ...
- Generation of ATP. ...
- Carbon Fixation.
Where does photosynthesis occur in plants?
In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll. Chlorophyll absorbs certain portions of the visible spectrum and captures energy from sunlight.
21 related questions foundWhat is photosynthesis in plants?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Does photosynthesis only occur in plants?
Photosynthesis is seen in plants, algae and some microbes. So, plants are not the only ones carrying out photosynthesis. The basic requirement of photosynthesis is sunlight, water, carbon dioxide and the chlorophyll contained in chloroplasts.
Does photosynthesis only occur in chloroplasts?
Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast.

What happens when photosynthesis occurs in a leaf?
Plants, unlike animals, can make their own food. They do this using a process called photosynthesis . During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light.
What are the two main processes of photosynthesis?
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.

What are the roles of chloroplasts and chlorophyll in 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.
Where is chlorophyll found in chloroplasts?
What makes a leaf green is chlorophyll, the green pigment located within the chloroplasts. More specifically, chlorophyll resides in the thylakoid membranes. The chlorophyll absorbs energy from sunlight, and it is this energy that drives the synthesis of food molecules in the chloroplast.
Does photosynthesis occur in stems?
Plant photosynthesis occurs in leaves and green stems within specialized cell structures called chloroplasts. One plant leaf is composed of tens of thousands of cells, and each cell contains 40 to 50 chloroplasts.
How do plants make food by photosynthesis?
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means 'making out of light'. The foods are called glucose and starch.
In which part of the chloroplast does photosynthesis occur?
Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves. The thylakoids sit inside the chloroplast and they contain chlorophyll which absorbs the different colours of the light spectrum to create energy (Source: Biology: LibreTexts).
What takes place in 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.
Which of these occur in photosynthesis?
Photosynthesis is the process in which autotrophs such as green plants use carbon dioxide and water in presence of sunlight to synthesize nutrients such carbohydrates in the form of glucose and release oxygen. In this carbon dioxide is reduced to glucose and water is oxidized to release oxygen.
Where does Calvin cycle take place in chloroplast?
Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
What happens during photosynthesis GCSE?
During photosynthesis: light energy is absorbed by chlorophyll - a green substance found in chloroplasts in the palisade cells in the leaf. absorbed light energy is used to convert carbon dioxide (from the air) and water (from the soil) into a sugar called glucose. oxygen is released as a by-product.
