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.
6,415 Questions
Diffusion. This is the passive movement of molecules from an area of high concentration to an area of low concentration, without the need for energy input.
What is the gas called that is given off photosynthesis?
Carbon dioxide
6CO2 + 6H2O -----> C6H12O6 + 6O2
When plant undergoes photosynthesis one of the by-products is?
They do share one big similarity and that is that the process of photosynthesis is the carbon dioxide needed to undergo photosynthesis, and plants and some bacteria. Photosynthesis: is a biological process in which green plant cells(mainly). Oxygen is produced as a by product during photosynthesis.
What is the sequence of energy transformation during photosynthesis?
solar energy → potential energy stored in electrons and ATP → chemical energy stored in sugars
Would a plant placed in a atmosphere of pure oxygen be able to conduct photosynthesis?
I believe that the answer to this is no because a plant also needs carbon dioxide around it. If it is just oxygen it could become overwhelmed and faint.
The initial activation energy for the process of photosynthesis is?
The initial activation energy for the process of photosynthesis is the energy required to initiate the conversion of light energy into chemical energy. This energy is used to break the bonds in the reactants and start the photosynthetic reactions.
Why is chlorophyll important in the process?
A membrane-bounded organelle with chlorophyll containing membranous thylakoids where photosynthesis takes place is called chloroplast. A green pigment that absorbs solar energy and is important in algae and plant photosynthesis is chlorophyll.
Explain how turgor pressure in a guard cell helps during photosynthesis?
Turgor pressure can cause a guard cell to close or open. As the guard cells take in water, it becomes turgid, causing the guard cells to bow, causing the stoma to open. By allowing the stoma to open, gases are able to enter. This is important because since gas rises, it allows CO2 to be captured, which is an important source for photosynthesis. It also allows gas exchange; a product of photosynthesis is oxygen, which then is allowed to be released into the environment through that opening. However, this causes water to be released, which is also an important resource for the photosynthesis.
On the other hand, if the cells become flaccid, there is less pressure on the guard cells, causing the stoma to close. This allows the plant to conserve its water and carbon dioxide.
What two things are produced during photosynthesis?
I do not really know. That is why I searched google.
Does mold go through photosynthesis?
No mold does not go though photosynthesis because it does not contain chlorophyll. Hence lacking the green color.
Why is energy needed for the proccess of photosynthesis?
Photosynthesis occurs in plants, algae, and many species of bacteria, but not in archaea.
Basically photosynthesis feeds/makes food for plants, algae and some bacteria. It has nothing to do with humans.
What is chlorophyll in a leaf?
Chlorophyll is the green coloration of the leaf and or plant.
It is the molecule that
absorbs sunlight and uses its
energy to make carbohydrates
from Carbon Dioxide and Water.
What are potential benefits of an increased rate of photosynthesis?
Photosynthesis is the single most important function in all of living things. An increased rate of photosynthesis will allow the process to be not as effective.
What is the relationship between photosynthesis and carbohydrates?
Carbohydrate are produced in photosynthetis.Glucose is produced first.
What type of organisms carry out photosynthesis?
Plants, algae, and some species of bacteria carry out photosynthesis. These organisms have chlorophyll, a pigment that allows them to capture sunlight and convert it into energy for growth and development. Photosynthesis is a crucial process for producing oxygen and organic compounds that sustain life on Earth.
What two things must be taken in by a plant for photosynthesis?
The two things that a plant takes in for photosynthesis are : light and carbon dioxide.
How do the equations of photosynthesis and cellular respiration compare?
To compare the equations for respiration an photosynthesis, you must first see what the equations are.
Respiration- sugar + oxygen = carbon dioxide + water + engergy
photosynthesis- carbon dioxide + water = light energy = sugar+ oxygen
The difference between these two equations are, they seem to be backwards from each other. So they are flipped around, see how respiration starts with sugar +oxygen and ends with carbon dioxide + water, but photosynthesis is the exact oposite.
What is the same about the two is they have the same "ingredients". :)
I hope this helped you to understand photosynthesis and respiration better. :) look below for the last answer that i improved by a lot. :)
idk, how i am i sposed to no this, i learned this in scince class lst year.;(
What is photosynthesis do for a plant?
Plants are able to make their own food by using photosynthesis.
Photosynthesis allows them to absorb energy form sunlight, CO2, and H20, in order to form glucose, releasing oxygen as well.
Plants are considered producers. They transform light energy into usable energy for cells, which is later passed on to organisms who eat them.
If photosynthesis life process stops what happens?
All green plants would die then oxygen breathing animals would all die; CO2 would no longer be converted to O2 - it would build up to toxic levels. Anaerobic bacteria would thrive, Aerobic bacteria would die out.
Explain what might happen if the third step of the Calvin cycle did not occur.?
I assume you have the Holt, Rinehart and Winston worksheets.
So your question was :
'If the RuBP consumed in Step 1 was not regenerated in Step 4 of the Calvin Cycle, then,
a. CO2 would stop diffusing into the stroma.
b. the cycle would speed up because of an increase in CO2 molecules.
c. the plant cell would lack G3P molecules.
d. the plant cell would stop bonding carbon atoms from CO2 into organic compounds
The two you can immediately cross out are A and B because diffusion of CO2 has nothing to do with RuBP. As for B, the cycle would not speed up. If anything, it would slow down or stop.
Now, we are left with:
c. the plant cell would lack G3P molecules.
d. the plant cell would stop bonding carbon atoms from CO2 into organic compounds
The article you read on the front sheet [I will not copy that down] never specified much on whether or not the cell would stop bonding carbon atoms from CO2 into organic compounds, so I personally settled for C. My reasoning behind this is that G3P is made from RuBP, and without it, the cell, like the answer states would lack G3P.
TL;DR the answer is 'D'
I do hope this helped. Good luck with Bio!
Edit: answer is D
When does photsynthesis take place?
The process by which green plants use light to synthesize organic compounds from carbon dioxide and water. In the process oxygen and water are released. Increased levels of carbon dioxide can increase net photosynthesis in some plants. Plants create a very important reservoir for carbon dioxide. (references)A chemical process during which plant cells, containing chlorophyll, use light to change carbon dioxide and water into carbohydrates and release oxygen as a by-product. (references)
ATP and NADPH
What organs are adapted for carrying out photosynthesis?
Plant cells contain numerous organs called mitochondria. This is where photosynthesis happens, which is the conversion of energy in light into chemical energy that is made available to the plant cell.
