6,415 Questions

Do chemoautotrophs do photosynthesis?

No they do not .They use chemical energy and CO2

What are the reactants and products in the processs of photosynthesis?

Photosynthesis uses the energy of sunlight to convert water and carbon dixode into high-engery sugers and oxygen.

Recants-carbon dixode and water

Products-high-energy sugars and oxygen

Is photosynthesis part of a plant's a. metabolism b. homeostasis c. development d. response to stimuli?

a. Metabolism. Photosynthesis is a metabolic process in plants where they convert carbon dioxide and water into glucose using sunlight as an energy source.

What are the products of photosynthesis and the reactants?

Carbon dioxide and water are the two reactants, and carbohydrates (glucose) and oxygen are the end products.

Sunlight is the energy source for the endothermic reaction. Along with glucose, products including ATP and other intermediary chemicals are produced.

What gas may be required for photosynthesis?

Carbon dioxide (CO2) is the gas required for photosynthesis. It is taken in by plants through small openings on their leaves called stomata and used along with water and sunlight to produce glucose and oxygen.

What is the literal meaning of photosynthesis?

The literal meaning is: To create or put together by using light - in other words, exactly what plants do to survive.

Why does photosynthesis occur faster between 0-35C?

The optimum temperature for photosynthesis to occur is actually 25 degrees celcius. The rate of reaction in photosynthesis is controlled by various factors such as the concentration of carbon dioxide and the temperature.

The temperature is highly important as enzymes in the reactions control how the reaction proceeds. If the temperature is too low, particles do not collide with sufficient force or frequency for the substrate and active site to become locked. If the temperature is too high, on the other hand, the enzymes become denatured and no longer work. This is because the active site of the enzyme is distorted and prevents substrates from binding to it.

What are raw materials found in nature called?

Examples of raw materials:

-Grains such as wheat and rice

-Vegetables such as carrots and onions

-Meat such as beef and chicken

-Wood from a tree

-Honey from a bee's nest

-Minerals or metal from a mine

-Crude oi

Which atmosphere gas is photosynthesis the major source of?

Oxygen is the major source of photosynthesis in the atmosphere. During photosynthesis, plants and other photosynthetic organisms convert carbon dioxide into oxygen through the process of photosynthesis. This oxygen is then released into the air, replenishing the levels in the atmosphere.

Is photosynthesis a way of reproducing?

No, photosynthesis is not a way of reproducing. It is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. Reproduction in plants typically involves the production of seeds or spores through processes such as pollination and fertilization.

Are animals characterized by photosynthesis?

Animals are actually characterized by their lack of photosynthesis. Animals lack the ability to create their own food, unlike plants. Animals are most often characterized by their ability to move via locomotion and their feeding habits. If there are any animals who have the ability to photosynthesize, it is currently unknown to mankind.

Does photosynthesis take place in money plant?

Yes, photosynthesis does take place in money plants. Money plants are capable of converting light energy into chemical energy through the process of photosynthesis, which helps them to grow and thrive.

How do the light reactions and dark reactions work together?

The light reactions provide energy carriers for the dark reactions.

Can a plant make photosynthesis without sunlight?

Yes, if there is another UV radiation source.

Plants grow by reacting water with carbon dioxide (from the air). This reaction is called photosynthesis and can only occur when energy is applied in the form of ultraviolet radiation.

An organism that does not require UV radiation for growth is not a plant.

Is chlorophyll b necessary for photosynthesis?

Chlorophyll is necessary for photosynthesis. It is located in the chloroplast and helps the plant with photosynthesis by helping the plant trap in sunlight. Without this, the plant would struggle to photosynthesize properly.

Hope this helps :D

What substances have to be present in a leaf for photosynthesis?

For photosynthesis to occur in a leaf, three key substances need to be present: sunlight, water, and carbon dioxide. Sunlight provides the energy needed for the process, water is absorbed from the soil and transported to the leaf through the plant's vascular system, and carbon dioxide is taken in from the air through tiny pores called stomata on the leaf surface.

Why are cellular repiration and photosynthesis opposite processes?

The process of photosynthesis is represented by the equation:

CO2 + H2O + sunlight (energy) ----> C6H12O6 +O2

The process of cellular respiration is represented by the equation:

C6H12O6 + O2 ----> CO2 +H2O + ATP (energy)

*C6H12O6 is glucose, a sugar.

As you can see, the products and the reactants of the equations are in reverse order when the two are compared. That means the reactants for photosynthesis are the products of cellular respiration, and vice versa.

What do plants need in their environment to carry out photosynthesis?

Carbon dioxide, water and sunlight. And enzymes like chlorophyll to catalyze the reaction.

CO2 (carbon dioxide), 6 H2O (water), enzymes, and sunlight. This is converted to C6H12O6 (glucose) + 6 O2.

What are three adaptations of plants that help reduce water loss in a desert or cold environment?

There are a variety of mechanisms- Many of the small mammals have special adaptations, such as convoluted nasal cavities and highly concentrated urine which conserves water- Many live underground, and so escape the heat of the day, and also underground is a more humid environment, so this also conserves water- Small mammals and other animals have less trouble coping with heat, because they are small, and so have a large surface area to radiate heat. The majority of activity occurs at night, so again escaping the heat...in desert climates, because the air is dry, there is significant cooling in the evening due to the fact that the air has a low heat capacity...in tropical climates heat is not as great a problem because there is plenty of water-the main way that animals cool themselves. Keep in mind, humid heat is only especially bad for humans and other sweating animals which cool themselves by evaporation. IN the absence of evaporative cooling, humidity doesn't have the same overheating effect as in humans. So, essentially it's a combination of staying underground and out of the heat of the sun during the day, and conserving water balance. IN addition, most of these animals can reduce their metabolism, thus decreasing internally generated heat.

What type of organisms can perform photosynthesis?

Plants, algae, and some bacteria are capable of photosynthesis. These organisms contain chlorophyll, a pigment that captures sunlight and converts it into chemical energy through the process of photosynthesis.

Which organisms undergo both photosynthesis and cellular respiration?

Plants, algae, and cyanobacteria are examples of organisms that can undergo both photosynthesis and cellular respiration. During the day, they perform photosynthesis to produce energy from sunlight, and at night or during times of low light, they switch to cellular respiration to generate energy from stored carbohydrates.

Is one what does not directly enables photosynthesis to take place in a leaf?

Photosynthesis is the making of a simple sugar that is food for a plant. A plant needs water, nutrients, sunlight, and and the Carbon Dioxide in air. If there isn't one of these things, a plant will not survive long.

What structure f the plant is the primary site of photosynthesis?

The primary site of photosynthesis in plants is the chloroplasts. These organelles contain chlorophyll, the pigment that absorbs light energy needed for the process of photosynthesis to occur. Within the chloroplasts, photosynthesis takes place in the thylakoid membranes where light reactions occur and in the stroma where the Calvin cycle (dark reactions) take place.

Which part of photosynthesis is water carbon dioxide and energy used?

In photosynthesis, light energy is captured by chloroplasts and used to knock an electron from watermolecules. The freed electrons are used to generate glucose sugars (used for the plant's growth and survival) from carbon dioxide, with water and oxygen as byproducts.
