6,415 Questions
What is the importance of photosynthesis in nature?
Photosynthesis is arguably the most important chemical process in biology because it converts light energy into usable chemical energy for life on Earth. It also produces O2 (oxygen) gas which is critical in cellular respiration. With the exception of a few species, life on Earth depends on photosynthesis.
What is the function of the thylakoid in the chloroplast?
It takes in light energy to make food for plants.
Is it the light absorbed or light reflected that initiates the light reactions of photosynthesis?
The light absorbed by chlorophyll initiates the light reactions of photosynthesis. Chlorophyll molecules in the thylakoid membranes of chloroplasts absorb light energy and convert it into chemical energy, which is used to drive the conversion of water and carbon dioxide into oxygen and carbohydrates during photosynthesis.
In which part ot a plant cell does photosynthesis take place?
, Photosynthesis is located in the thylakoid of the chloroplast of a cell. The chloroplast has pigments named chlorophyll, and it is what makes plants green. Photosynthesis is the process of changing sunlight into a usable energy source, which is normally glucose (sugar). The chemical equation of this process would be:
6H2O + 6CO2 ----------> C6H12O6+ 6O2
The emission of oxygen is also a product of photosynthesis, as the process only uses the hydrogen within the water and the oxygen becomes useless for the plant.
Good Luck!
What substance is removed from the atmosphere so that plants can carry out photosynthesis?
That is carbon dioxide. It is a raw material
Describe the second portion of photosynthesis?
The second portion of photosynthesis is the light-independent reactions, also known as the Calvin cycle. During this stage, carbon dioxide is used to produce glucose by utilizing ATP and NADPH generated in the light-dependent reactions. The Calvin cycle takes place in the stroma of the chloroplast.
What product of photosynthesis is the starting material for cellular respiration?
The products of photosynthesis that is also the starting material for cellular respiration is sugar and oxygen. photosynthesis: 6CO+6H2O----->(with light energy)C6H12O6+O2+ ENERGY (ATP) Carbon dioxide + Water------> sugar+ oxygen+ energy Cellular respiration: C6H12+ 6O2-----> 6CO2+ 6H2O+ Energy Sugar+ oxygen ------> water+ carbon dioxide + energy
Can plants use artificial light instead of sunlight?
yes they can use. they absorb energy from the light.
What organelle used in photosynthesis?
No organelle makes photosynthesis.
However, the process of photosynthesis occurs in the chloroplasts of a plant cell.
The question should be "Which organelle is used to make chlorophyll". The plants are responsible for making their own energy unlike animals which get their energy from plants.
What are 2 waste products of photosynthesis?
there are two types of wastes products produced by plants
a)gaseous
B)liquid
Gaseous wastes include carbon dioxide(CO2) and oxygen(O2). While the former is produced during the respiration of the plant, the latter is produced in a process called photosynthesis.
Liquid waste is water(H2O)
Both of these wastes are removed by stomata.
How are human beings benefited to photosynthesis?
Humans benefit from photosynthesis indirectly by relying on plants to produce oxygen, which is necessary for human respiration. Additionally, plants are a crucial part of the food chain, providing us with essential nutrients and energy. Through photosynthesis, plants help maintain the balance of gases in the atmosphere and provide habitat for many organisms that directly or indirectly benefit humans.

photosynthesis sorry it's not a lot (LOL) by EMILY CRUZ age 12 AND FRIENDS ( SO BYE )
Plant organ which photosynthesis takes place?
It takes place in chloroplasts.They are organelles with photosynthetic pigments.
Why can't photosynthesis happen without cellular respiration?
Photosynthesis will come to a halt without sunshine. Cellular respiration can and does occur 24 hours a day, 7 days a week.
Photo autotrophs ,like plants, do photosynthesis to obtain light energy. Hemo autotrophs, like bacteria, do hemosynthesis to make organic molecules by using the chemical energy from inorganic molecules.
What is the role if ATP synthase in photosynthesis?
The pigment molecules and electron transport chains involved in the light-dependent reactions of photosynthesis are embedded in the thylakoid membrane. As energy is released from electrons traveling through the chain of acceptors, it is used to pump protons (that is, H+ ions) from the stroma of the chloroplast across the thylakoid membrane and into the center of the thylakoid. Thus, protons accumlate within the thylakoids, lowering the pH of the thylakoid interior and making it more acidic. A proton gradient possesses potential energy that can be used to form ATP.
Protons are prevented from diffusing out of the thylakoid because the thylakoid membrane is impermeable to protons except at certain points bridged by an enzyme called ATP synthase. This protein extends across the thylakoid membrane and forms a channel through which protons can leave the thylakoid. As the protons pass through ATP synthetase, energy is released, and this energy is tapped by ATP synthase to form ATP from ADP and inorganic phosphate. The coupling of ATP synthesis to a protein gradient formed by energy released during electron transport is called chemiosmosis.
Is photosynthesis matter or energy?
Neither-Photosynthesis is the process that a plant uses to make its food, which is glucose, that is made into energy.
photosynthesis uses sunlight and carbon dioxide, and makes the products:glucose (C6H12O6 ) and oxygen.
Which equation best represents the process of photosynthesis?
Carbon dioxide + water + glucose + oxygen
What is the reactants for photosynthesis?
carbon dioxide and water (with sunlight and chlorophyll - in chloroplasts)
What equation summarizes the process of photosynthesis?
photosynthesis is the process that plant cellsuse to change th energy from sunlight, photosynthesis are carbon dioxide and water. The process takes place when carbon dioxide and water enter the plant's chloroplasts.
Source of carbon dioxide for photosynthesis is?
The air which takes its CO2 from respiration of animals and various other organisms.
What are the 2 products of the light reaction used in the Calvin Cycle?
There are two types of plants. IT could be PGA or OAAas results.
Do plants give off heat during respiration?
Respiration is the process by which plants take in oxygen and give out carbon dioxide. As shown in Figure 4.5, oxygen from the air breaks down carbohydrates in the plant into carbon dioxide and water. This reaction produces energy in the form of heat.
Respiration is a basic reaction of all plant material, both in the field and after harvest. It is a continuing process in the growing plant as long as the leaves continue to make carbohydrates, and cannot be stopped without damage to the growing plant or harvested produce.
Fresh produce cannot replace carbohydrates or water after harvest. Respiration uses stored starch or sugar and will stop when reserves of these are exhausted; ageing follows and the produce dies and decays......Effect of air supply on respiration. Respiration depends on a good air supply. Air contains about 20 percent of the oxygen essential to normal plant respiration, during which starch and sugars are converted to carbon dioxide and water vapour. When the air supply is restricted and the amount of available oxygen in the environment falls to about 2 percent or less, fermentation instead of respiration occurs. Fermentation breaks down sugars to alcohol and carbon dioxide, and the alcohol produced causes unpleasant flavours in produce and promotes premature ageing..................................................The effect of carbon dioxide on respiration. Poor ventilation of produce because of restricted air supply leads also to the accumulation of carbon dioxide around the produce. When the concentration of this gas rises to between I and 5 percent in the atmosphere, it will quickly ruin produce by causing bad flavours, internal breakdown, failure of fruit to ripen and other abnormal physiological conditions. Thus, the proper ventilation of produce is essential...........
What is the raw material of photosynthesis?
You might mean the reactants, the reactants for photosynthesis are 6CO2 + 6H2O+ light energy. The products from these reactants are Oxygen, Glucose.
Photosynthesis:
6CO2+6H2O+light energy--->6O2+C6H12O6.
What during this process plants use light energy to produce food?
"Photosynthesis" is the process that plants use to utilize energy to produce their own food.
