How do photosynthesis and respiration depend on one another?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Why is the relationship between photosynthesis and respiration considered a cycle?
Cellular respiration and photosynthesis are considered a cycle because the product (end material) of one reaction serves as the starting material for the other reaction. The starting material for cellular respiration is sugar and water and the products are carbon dioxide and water.
Can photosynthesis and respiration occur without each other?
Cellular respiration cannot occur without photosynthesis, and photosynthesis certainly cannot occur without the help of its partner.
Why do we depend on photosynthesis?
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. The importance of photosynthesis in our life is the oxygen it produces.
Where does photosynthesis take place in a cell?
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.
Where does photosynthesis and cellular respiration take place?
mitochondria
Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria. Photosynthesis makes glucose and oxygen, which are then used as the starting products for cellular respiration.
Why do plants need to do both photosynthesis and cellular respiration?
Just like animals can’t live without cellular respiration, plants can’t live without cellular respiration, either. Photosynthesis and respiration in plants are complementary processes because photosynthesis is only one half of the process of getting energy for a plant. It’s how they make food, not how they consume it.
Do plants respire and photosynthesis at the same time?
Plants respire all the time, whether it is dark or light. They photosynthesise only when they are in the light. Photosynthesis usually results in a gain of glucose once respiration has been accounted for. Plants that lose their leaves in winter store food produced during the summer by photosynthesis.
Which part of the cell does respiration happen?
Mitochondria
Key Terms
| Term | Meaning |
|---|---|
| Mitochondria | The eukaryotic cell structure where cellular respiration occurs |
| Cytoplasm | The contents of a cell between the plasma membrane and the nuclear envelope; includes cytosol which is the jelly-like substance that fills the space between organelles |
| Aerobic | Process that requires oxygen |
How are cellular respiration and photosynthesis alike and different?
The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.
What are the similarities between photosynthesis and cellular respiration?
Photosynthesis and cellular respiration are similar because both reactions contain water, carbon dioxide, glucose, oxygen and energy. They are different, because the reactions are opposites of each other.
What are the things needed for photosynthesis to occur?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).
What are the processes of photosynthesis and transpiration?
is that photosynthesis is (biology) the process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy while transpiration is (botany) the loss of water by evaporation in terrestrial plants, especially through the stomata; accompanied by a corresponding uptake from the roots.
How do you explain the process of photosynthesis?
How to Explain Photosynthesis Method 1 of 3: Explaining Why Photosynthesis is Needed. Discuss how plants create oxygen. Method 2 of 3: Discussing the Light Dependent Reactions. Break down the chloroplasts. Method 3 of 3: Examining the Light Independent Reactions. Recognize that the products from light dependent reactions drive light independent reactions.
