What is the location of the photosynthetic factory?
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.
What is photosynthesis bullet points?
Photosynthesis refers to a set of chemicals reactions in which energy from the sun changes carbon dioxide and water into glucose and oxygen. Sunlight is most often harnessed by chlorophyll, which is green because it reflects green light. However, there are other pigments that also work.
Where does photosynthesis occur 1pt?
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.
How does photosynthesis work BBC?
Key points. Photosynthesis is a process that occurs in the leaves of a plant and needs both chlorophyll and light energy. During photosynthesis, the chlorophyll in leaves help convert carbon dioxide and water into the products oxygen and glucose. The product glucose acts as a vital source of food for the plant.
Where does the most photosynthesis on Earth occur?
Since the oceans occupy about 70% or the majority of the Earth’s surface, this is also where most photosynthetic processes occur. Photosynthesis in the ocean is mainly done by marine autotrophs in the photic zone, such as algae, kelps, seaweeds, and phytoplankton, that contain chlorophyll.
How did you know that photosynthesis has taken place?
How can we tell if they are performing photosynthesis? One way is to see if they are giving off oxygen, the most important byproduct of photosynthesis. Of course, we can’t usually see leaves producing oxygen, but watch what happens when you use an underwater plant!
Who does the most photosynthesis on Earth?
algae
Most of the photosynthesis (80%) which takes place on this earth is carried out by algae present in fresh water and ocean water. At least a half of the total carbon dioxide fixation on earth is carried out by algae through photosynthesis.
What plant produces the most oxygen in the world?
One type of phytoplankton, Prochlorococcus, releases countless tons of oxygen into the atmosphere. It is so small that millions can fit in a drop of water. Prochlorococcus has achieved fame as perhaps the most abundant photosynthetic organism on the planet. Dr.
At what time of day does photosynthesis take place?
For photosynthesis the plant takes in carbon dioxide light energy and water to produce glucose and oxygen. Photosynthesis only happens during the daytime when there is enough sunlight. However plants can respire at all times of the day and night even though their stomata close at night.
When was photosynthesis first used?
3.4 billion years ago
Timeline of Photosynthesis on Earth
| 4.6 billion years ago | Earth forms |
|---|---|
| 3.4 billion years ago | First photosynthetic bacteria appear |
| 2.7 billion years ago | Cyanobacteria become the first oxygen producers |
| 2.4 – 2.3 billion years ago | Earliest evidence (from rocks) that oxygen was in the atmosphere |
What did Melvin Calvin discover about photosynthesis?
Calvin shone light on the lollipop and used a radioactive form of carbon called carbon-14 to trace the path that carbon took through the algae’s chloroplast, the part of the cell where photosynthesis occurs. By this method, he discovered the steps plants use to make sugar out of carbon dioxide.
What are 4 facts about photosynthesis?
10 Facts on Photosynthesis
- The green color of leaves is due to chlorophyll.
- The two main parts of a chloroplast are the grana and stroma.
- The first stage of photosynthesis captures energy from the sun to break down water molecules.
- The second stage of photosynthesis is the Calvin cycle.
What is photosynthesis short answer?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Do trees photosynthesize at night?
No, plants do not perform photosynthesis at night. Plants can perform photosynthesis at night only if they are provided with the artificial light of the corresponding wavelengths.
