Photosynthesis
This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

Where in a cell do the light reaction of photosynthesis occur?
The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplasts. These reactions involve capturing light energy to drive the conversion of water into oxygen, ATP, and NADPH molecules, which are essential for the next stage of photosynthesis.
Is the oxygen liberated during photosynthesis equal to the amount used in respiration by plants?
No, it must be more.
Remember respiration by animals plus the storage in the atmosphere.
Plus random oxidation.
Cellular respiration is possible without photosynthesis in an organism but photosynthesis is not possible without cellular respiration.
Where does a plant get the carbon dioxde that it needs for the dark reaction of photosynthesis?
The plants uses stored carbohydrates such as starches.
Where does the oxygen produced in the dark reaction of photosynthesis come from?
It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction

What is the meaning of homide?
found no definitions for "homide"
Did you mean "homicide" which is the same as "murder"?
The chemical change of the sun's energy into glucose and oxygen-?
Photosynthesis is the chemical change of the suns energy into glucose and oxygen.
Do plants turn gren on the second stage of photosynthesis?
No not in the second step. First step is responsible
Will photosynthesis take place in foil covered leaf?
no because the leaves or anyother part of the plan has to be exposed to the sun so the energy from the light will hit the plant and it can crreate sugar to supply energy (with carbon dioxide as well)
The most important part of the speech "What It Means to be Colored in Capital of the U.S." by Mary Church Terrell is when she emphasizes the importance of African Americans embracing their identity and not feeling inferior or ashamed of their race. Terrell's message of empowerment and self-respect encourages black Americans to stand up against racism and discrimination.
How many types of chlorophyll?
Tell me and i want to know more about in this topic can chlorophyll give us energy to build our body
How is the greenhouse effect related to photosynthesis?
The only relation there is between the two is carbon dioxide (CO2).
Carbon dioxide is a greenhouse gas. Too much of it in the atmosphere causes the 'greenhouse effect' whereby the earth warms.
In the photosynthesis process CO2 is captured from the atmosphere and, with the help of sunlight (and water in the case of plants) turned into organic compounds. A waste product of this process is oxygen.
What is light energy and what does it do for cellular respiration?
Light energy does not affect respiration, but it is needed for photosynthesis, which in plants creates the chemical compounds (carbohydrates) that are oxidized in cellular respiration.
Which sequence correctly shows the path of carbon dioxide respiration?
body cells, capillaries, alveoli
How water is involved in the process of digestion and photosynthesis?
water is a necessity for digestion because it helps your stomach to break up the particles in your food.
The stractures in most seed plants where the food making process occurs are the?
The structures in most seed plants where the food-making process occurs are the chloroplasts. Inside the chloroplasts, photosynthesis takes place, where carbon dioxide, water, and sunlight are converted into glucose (sugar) and oxygen. These chloroplasts are mainly found in the cells of the leaves, where they capture sunlight and produce food for the plant.
How does sunlight affect food packaging?
Sunlight can affect food packaging by spoiling the contents inside. It can result in deterioration of the food and the packaging material can be absorbed, scattered and transmitted through the food.
Is photosynthesis a noun or a verb?
Photosynthesis is a noun. It refers to the process by which green plants and some other organisms use sunlight to synthesize food from carbon dioxide and water.
What are the similarities between photosynthesis and respiration?
Photosynthesis is a system in plants for the taking of suns energy and creating food (mainly glucose). This process requires CO2 and water according to this general equation:
6CO2 + 6H2O + Energy ® C6H12O6 + 6O2
Notice here that Glucose (C6H12O6) and oxygen (O2) are products here
This differs from cellular respiration in the fact that Oxygen and Glucose are reactants and Carbon dioxide and waters are products :
C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy
You will here notice that they are essentially the reverse equations.
These are how they are similar:
- Both systems involve the movement of electrons through "electron transport chains"
- ATP is created through APT synthase and an electrochemical gradient (Hydrogen ions)
- Both take place in a organelle thought to have been ingested (reason for the double membranes of mitochondria and chloroplasts)
