6,415 Questions

What must be available in order for photosynthesis to occur?

In order for photosynthesis to occur, CO2 must be captured from the environment and broken down into carbon and Oxygen via sunlight. The carbon is used for the plant while the oxygen is released.

Does photosynthesis happen under black filter paper?

If the paper is thick enough to prevent any light from passing through it then no photosynthesis will occur in the area covered by the paper.

Products in the process of photosynthesis?

The products of photosynthesis are glucose (sugar) and oxygen. During photosynthesis, plants use carbon dioxide and water, along with sunlight energy, to produce these products. This process is essential for the growth and survival of plants and is also the source of oxygen in the atmosphere.

Phase of photosynthesis where light energy is converted to chemical in form of ATP?

The phase of photosynthesis where light energy is converted to chemical energy in the form of ATP is called the light-dependent reactions. During these reactions, light is absorbed by chlorophyll and other pigments in the thylakoid membranes of the chloroplast, leading to the generation of ATP and reducing power (NADPH) that will be used in the Calvin cycle to produce sugars.

What is the first phase of photosynthesis?

The first phase of photosynthesis is the light-dependent reactions, which occur in the thylakoid membranes of chloroplasts. In this phase, light energy is captured and used to split water molecules into oxygen, protons, and electrons.

Where do the light-idependent reactions pf photosynthesis take place?

The light-independent reactions of photosynthesis take place in the stroma of the chloroplasts. This is where carbon fixation and the Calvin cycle occur, utilizing the products of the light-dependent reactions to produce glucose.

What do the raw materials include?

Raw materials usually include natural resources or primary ingredients that are used in the production of goods or products. These materials are often in unprocessed or minimally processed form and can vary depending on the industry or product being manufactured. Examples of raw materials include wood, metals, minerals, and agricultural products.

What are the raw materials in making efficascent oil?

The raw materials in making Efficascent oil include menthol, eucalyptus oil, camphor, and mineral oil. These ingredients are combined to create a soothing and aromatic oil that is commonly used for relieving muscular aches and pains.

The efficiency of each stage of energy production can be determined by?

The efficiency of each stage of energy production can be determined by measuring the net amount of ATP produced. During the initial steps of respiration there is a net of 2 ATP, by the oxidative phase there is a net of 36 ATP produced.

What functions to convert light energy to chemical energy that is stored in the chemical bonds of glucose or starch?

Photosynthesis is the process through which plants convert light energy into chemical energy stored in the form of glucose or starch. It involves capturing sunlight, using it to convert carbon dioxide and water into glucose, and releasing oxygen as a byproduct. This process occurs in the chloroplasts of plant cells using pigments like chlorophyll.

What happens to the rate of photosynthesis when the CO2 levels exceed 3 percent?

When CO2 levels exceed 3 percent, the rate of photosynthesis typically increases initially due to the increased availability of the substrate for photosynthesis. However, beyond a certain point, the rate of photosynthesis can decrease as the high CO2 levels may lead to photorespiration and other metabolic imbalances in the plant cells.

In what leaf tissue does gas exchange occur most easily?

Gas exchange in plants occurs on the underside of leaves though tiny holes called stomata on the lower epidermis. They are located on the underside in order to shield the stomata from direct sunlight, which would increase evaporation through them, dehydrating the plant.

Carbon dioxide is given off during photosynthesis?

This statement is incorrect. During photosynthesis, plants use carbon dioxide from the atmosphere and water to produce glucose and oxygen. The oxygen is released as a byproduct, not the carbon dioxide.

The dark reactions require all of these chemicals to proceed except?

The dark reactions, also known as the Calvin cycle, do not require light. It is a series of chemical reactions that occur in the chloroplasts of plants to convert carbon dioxide into glucose using ATP and NADPH generated in the light reactions.

Can you perform taxidermy on a human?

Physically, yes. Legally....maybe for scientific purposes if they "left their body to science" after they die.

How can you tell that photosynthesis can not take place in a root cell?

Photosynthesis occurs in the chloroplasts of plant cells, which are typically found in the leaves. Root cells do not contain chloroplasts and are not exposed to sunlight, so photosynthesis cannot take place in a root cell. Roots primarily function in absorption of water and nutrients from the soil.

How does coleus photosynthesis?

Coleus plants undergo photosynthesis in their chloroplasts, utilizing water, carbon dioxide, and sunlight to produce glucose (sugar) and oxygen. The chlorophyll pigment in the leaves absorbs sunlight energy, which is then converted into chemical energy through a series of reactions involving enzymes and other molecules. This process fuels the plant's growth and provides it with the nutrients needed for survival.

What is the experiment to prove that oxygen is released during photosynthesis?

In 1770, Joseph Priestly conducted experiment to discover one of the products of photosynthesis. He first put a mouse into a bell jar and left it, it died. He then put a burning candle into the bell jar and it burnt out. After that, he placed a plant into the bell jar with another mouse, it survived! And, then he placed a candle in with the plant, it didn't burn out! So using our knowledge of respiration and combustion we know that you need oxygen to burn and oxygen to respire.

Where does photosynthesis happen in a cell?

Photosynthesis occurs in the chloroplasts of plant cells. These organelles contain chlorophyll, the pigment that captures light energy and converts it into chemical energy through the process of photosynthesis.

Where does the NADPH created during the light reactions accumulate?

NADPH is created in the stroma of the chloroplasts during the light reactions of photosynthesis. It accumulates in the stroma where it is used in the Calvin cycle to help convert carbon dioxide into sugars.

What type of organization owns all elements from raw materials to finished products?

A vertically integrated organization owns all elements of the supply chain, from raw materials to finished products. This type of organization controls the entire production process, allowing for greater control over quality, cost, and delivery times.

The food manufactured by the process of photosynthesis is stored by the plant as?

The food manufactured by photosynthesis is stored in the form of glucose or starch in the plant's cells. This stored energy is used for growth, reproduction, and to fuel metabolic processes within the plant.

Why do humans suffocate at night when the plants around them cannot photosynthesis?

your question is odd, because most people don't sleep with plants around them to begin with

however if I had to answer this for a million dollars I would say that as through photosynthesis plants produce oxygen, lack of photosynthesis would mean a lack of oxygen where the person is sleeping, and I suppose under certain conditions, there would be too low levels of oxygen and the person could not breath

it makes some sense, but then not really, it would have to be in an airtight room or outer space so no oxygen could enter the room and there would have to be little or no oxygen in the room to begin with

hope this helps

What factors can affect the rate of photosynthesis in a plant?

Factors that can affect the rate of photosynthesis in plants include light intensity, carbon dioxide concentration, temperature, water availability, and the presence of chlorophyll. Any imbalance in these factors can limit or enhance the ability of a plant to carry out photosynthesis efficiently.

Links between energy of carnivores and photosynthesis?

Carnivores obtain their energy by consuming other organisms, including herbivores that obtain energy from photosynthesis. Photosynthesis is the process by which plants and some bacteria convert sunlight into chemical energy stored in the form of glucose. Carnivores rely on this stored energy indirectly through the food chain.
