What type of energy does photosynthesis use?

Photosynthesis uses light energy from the sun to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells.

What might happen if plants could not perform photosynthesis?

in photosynthesis the light energy converted into chemical energy. carbohydrates forms, corbon fixes in leaves. all the metabolic activities in plant body depends on the energy tapped through photosynthesis. metabolic activities are must & should for all living organisms for their survival.

when photosynthesis not peformed,

1.all the metabolic activities will stop

2. due to that growth stops

3.senescence will occur

4.slowly & slowly plant leads to death & it will die.
-Oxygen would be eliminated from the atmosphere. -Carbon would fulfill its role, causing global warming.

-Producers would die, not being able to gain nutrients from photosynthesis and respiration.

-The food chain would perish due to all the dead producers.


If there was no photosynthesis, the provision of oxygen by the Ocean's phytoplankton and the Earth's plants would be lost.Also it would lead to an increase in the degree of global warming as noxious poisons accumulate in the atmosphere.And the FOOD CYCLE would be disturbed as The Food Chain starts with plants as they produce glucose through photosynthesis.

Photosynthesis is part of this continuous movement?

Photosynthesis is a process where plants convert light energy into chemical energy to produce glucose, releasing oxygen as a byproduct. It is part of the continuous movement of energy and nutrients through ecosystems, as plants are the primary producers that support the entire food web. This process is crucial for the survival of many organisms and plays a key role in the balance of oxygen and carbon dioxide in the atmosphere.

How do people benefit from photosynthesis?

People benefit from photosynthesis because it is the process by which plants convert sunlight into energy and produce oxygen as a byproduct. This oxygen is essential for humans to breathe, while the energy produced by photosynthesis is consumed by plants and passed on to animals that eat plants, forming the basis of the food chain.

What are tiny organisms that float in the oceans and make their own food through the process of photosynthesis called?

They are called phytoplankton. These microscopic algae are crucial to the marine food web as they serve as the primary producers, converting sunlight into energy through photosynthesis.

Which of the following is involved in long-term blood pressure regulation?

Heart rate, the constriction of the arterial walls (reducing/increasing the volume of the circulatory system) and the blood volume in the circulatory system. If you wish to increase or decrease blood pressure, you can do this through adjusting any of the above and more.

The ability to make an image appear larger than it actual size s called?

Magnification. If its a Biology term question, they probably worded it weird like they did with mine.

Can the mesosphere absorb anything?

Mesosphere can absorb anything perhapes yea your accutaly to add to the answer works exactly like a dream think of it this way, somebody is comunticating with you he is talking about a space ship the meantal conception incepts and absorbs the noise and the soundramitcal displeance from that persons mouth that your comunticating with, i know its confusing but what happens after that the cycle that your has to procced with it puts the brain under pressure but us human don't feel because of the dismaticall order relaxs the brian so you don't feel it as much, now as it start spreading the dismaticall liqued will help the brain then the phsaulacting web disdrafts the combination so your accutaly absorben the the soundramitcal displeance, like in space the cycle of the transportation around the sun happens it accumulate all the abosbtion of every planet, like the say the underworld has alot for people to learn, yea now your brain asocialices the accumulated particles like when your dreaming and the inside of that dream your castrolition dream that what they that's when your in the dream what ever happen in there, happens in reality unfortunately the brain start attacking the human body disorderly you hurt you leg in that dream of the dream the ammount its hurting its in reality so try to snap and wake out of it or sleepdream in the your dreaming. Lol abit long but just in there and you will learn alot that's what biologicall inceotion is it has being proved as a reality cofirm.

What absorbs light energy in photosynthesis?

Chlorophyll molecules are responsible for absorbing light energy in photosynthesis. These molecules are found in the chloroplasts of plant cells and are able to capture light energy to drive the process of converting carbon dioxide and water into glucose.

When water becomes limited what generally happens to the rate of photosynthesis?

When water becomes limited, the rate of photosynthesis typically decreases. Water is a necessary component for photosynthesis because it is used in the process of converting carbon dioxide into glucose. Without enough water, plants are unable to produce sufficient energy to support photosynthesis.

How is wind pollinating a flower similar to an insect pollinating a flower?

They both produce pollen, therefore they must have anthers and since they both produce seeds they must have stigmas


The end results of wind pollination and insect pollination are the same, the plants are pollinated.
Wind pollinated plants, which include the grasses and some trees, have either no flowers or very insignificant flowers because they have no need to attract insects. The anthers produce very large amounts of very small pollen grains which are then blown by the wind in the hope of hitting a stigma of the same variety of plant. This is the type of pollen which is the major cause of hay fever.
Insect pollinated plants will have flowers, usually with nectar, to attract the insects and reward them with food. A bee's body is covered with fine hairs which become charged with static electricity as the insect flies so when it lands on the flower the pollen grains are actually attracted to the bee's body. When the bee goes to the next flower, some of this pollen is transferred to the flower's stigma. Pollen grains of insect-pollinated plants are much larger than those of wind-pollinated plants.

What would have to the oxygen content in the air if photosynthesis were stop?

The oxygen content in air would have decreased.

This is because photosynthesis is a process which keeps the balance between oxygen and carbon dioxide by converting carbon dioxide to oxygen.

What are the most important compounds in photosynthesis?

The most important compounds in photosynthesis are water, carbon dioxide, and glucose. Water is used in the light-dependent reactions to produce oxygen and ATP. Carbon dioxide is used in the light-independent reactions to produce glucose through the Calvin cycle. Glucose is the primary product of photosynthesis and serves as an energy source for plants and other organisms.

Most respiration occurs in organelles called?

Most respiration occurs in organelles called mitochondria. Mitochondria are known as the powerhouse of the cell because they generate ATP, which is the energy currency of the cell, through a process called cellular respiration.

An important by-product of photosynthesis?

Oxygen is an important by-product of photosynthesis. During photosynthesis, plants and algae use sunlight to convert carbon dioxide and water into glucose and oxygen. Oxygen is released into the atmosphere as a waste product, which is essential for respiration in animals and other organisms.

Which of the organelles takes up the majority of the volume of the plant cell and is used for food and water storage?

The vacuole is the organelle that takes up the majority of the volume in a plant cell. It is used for storing water, nutrients, and waste products. The central vacuole in plant cells helps maintain turgor pressure and provides structural support to the cell.

How can a person make sure that plants can get all the nutrients that they need?

By planting in a soil that contains the needed nutrients or add a fertilizer that contains the necessary nutrients. The three primary nutrients that are required are nitrogen(N), phosphorus(P), and potassium(K). There is a host of secondary nutrients such as calcium(Ca), sulphur(S), and magnesium (Mg)

What happens to the extra energy in excited electrons as they pass along an electron trandsport chain in a chloroplast?

The extra energy in the excited electrons is used to pump hydrogen ions across the thylakoid membrane, creating a proton gradient. This gradient is then used to drive ATP synthesis during the process of chemiosmosis, providing energy for cellular activities.

What will happen if you move the hydrilla away from the light?

If you move hydrilla away from light, its growth will be stunted as it requires light for photosynthesis, which is crucial for its survival and growth. The plant may weaken, turn yellow, and eventually die if it's consistently deprived of light.

Why are pigments such as chorophyll needed for photosynthesis?

Pigments like chlorophyll are needed for photosynthesis because they are capable of absorbing light energy. This energy is then used by plants to convert carbon dioxide and water into glucose, a process crucial for the plant's growth and survival. Without chlorophyll, plants wouldn't be able to capture and utilize sunlight effectively for photosynthesis.

Where do electrons get their energy in photosynthesis?

Electrons in photosynthesis obtain their energy from sunlight. The process involves capturing light energy to excite electrons in chlorophyll molecules, which are then passed through a series of electron carriers in the thylakoid membrane of chloroplasts to generate chemical energy in the form of ATP and NADPH.

What happens to the product of photosynthesis?

The product of photosynthesis is glucose, which is used by the plant as an energy source for growth, reproduction, and other metabolic processes. Additionally, oxygen is produced as a byproduct and released into the atmosphere.

What type of cells does photosynthesis take place in?

Photosynthesis takes place in chloroplasts, which have chlorophyll in them. Chlorophyll absorbs the sunlight. From sunlight, green plants combine carbon dioxide and water to make sugar and oxygen.

Why does the oxidation of organic compounds by molecular oxygen to produce CO2 and water release free energy?

The oxidation of organic compounds by molecular oxygen releases free energy because the bonds in the organic compounds are more stable than the bonds in the products (CO2 and water). When the organic compounds are oxidized, new bonds are formed and energy is released in the process. This energy is made available for cellular processes such as ATP production.

Is carbon dioxide made or used up in photosynthesis?

No, carbon dioxide is used during photosynthesis. It is necessary for the Calvin-Benson cycle because it is attached to RuBP to start the cycle. This cycle ultimately produces glucose. However, carbon dioxide is made as a by-product of cellular respiration.
