What is photosynthesis and in what organelle does occur?
Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy.
What is the process of photosynthesis called?
This is called oxygenic photosynthesis and is by far the most common type of photosynthesis used by living organisms. Carbon dioxide is converted into sugars in a process called carbon fixation; photosynthesis captures energy from sunlight to convert carbon dioxide into carbohydrate.
Where does each step of photosynthesis occur?
The stages of photosynthesis
| Stage | Location | Events |
|---|---|---|
| Light-dependent reactions | Thylakoid membrane | Light energy is captured by chloroplasts and stored as ATP |
| Calvin cycle | Stroma | ATP is used to create sugars that the plant will use to grow and live |
What are the three steps of photosynthesis?
The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.
What are the 3 process of photosynthesis?
What does grana do in photosynthesis?
Grana (plural of ‘granum’) are stacks of structures called thylakoids, which are little disks of membrane on which the light-dependent reactions of photosynthesis take place. Stacked into grana, the shape of the thylakoids allow for optimum surface area, maximizing the amount of photosynthesis that can happen.
What cell organelle does photosynthesis take place in?
Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. If you examine a single leaf of a Winter Jasmine leaf, shown in Figure below, under a microscope, you will see within each cell dozens of small green ovals. These are chloroplasts, the organelles which conduct photosynthesis in plants and algae. Chloroplasts closely resemble some types of bacteria and even contain their own circular DNA and ribosomes.
How does photosynthesis affect cellular respiration?
The rate of photosynthesis decreases with increase in temperature, whereas cellular respiration increases with an increase in temperature up to a certain point. It has been found that lower the temperature, lower the compensation point and that the maximum photosynthesis is achieved at lower temperatures.
How does cellular respiration compare to photosynthesis?
The key difference between photosynthesis and cellular respiration is that photosynthesis utilizes carbon dioxide and water to produce glucose and oxygen while cellular respiration utilizes glucose and oxygen to produce energy, carbon dioxide, and water.
What are specialized photosynthetic organelles?
Photosynthesis in plants occurs in specialized organelles called chloroplasts. Chloroplasts are found in plant leaves and contain the pigment chlorophyll. This green pigment absorbs light energy needed for photosynthesis to occur.
