What is the mitochondria's role in photosynthesis?

Mitochondria are not directly involved in photosynthesis. Instead, they are responsible for generating energy in the form of ATP through cellular respiration, which occurs in the cytoplasm and mitochondria of eukaryotic cells. Photosynthesis takes place in chloroplasts, where light energy is converted into chemical energy in the form of glucose.

Name the gas made in photosynthesis?

Human beings breath in oxygen, and breath out CO2. The plant's leaves, when making photosynthesis, use CO2 and a few other things to make photosynthesis. When finished with making photosynthesis, the leaves release some oxygen, which is the gas we use to breathe. Thus, oxygen is the useful gas made by photosynthesis.

What three elements are the basic building blocks of sugars?

Carbon, hydrogen, and oxygen are the basic building blocks of sugars. These elements combine to form simple sugar molecules like glucose, fructose, and sucrose, which are important sources of energy for living organisms.

How were Priestley's and Ingenhousz' discoveries about photosynthesis related?

Priestley discovered that plants release oxygen in the presence of light, while Ingenhousz found that plants only release oxygen in the presence of both light and green parts of the plant. Together, their discoveries laid the foundation for understanding photosynthesis as the process by which plants use light energy to produce oxygen and convert carbon dioxide into carbohydrates.

An inorganic molecule reguired by green plants for the process of photosynthesis is?

Carbon dioxide (CO2) is the inorganic molecule required by green plants for the process of photosynthesis. During photosynthesis, carbon dioxide is converted into glucose in the presence of sunlight and chlorophyll.

Which gas does photosynthesis produce?

Photosynthesis produces oxygen gas (O2) as a byproduct. During the process, plants and other photosynthetic organisms take in carbon dioxide and water, and in the presence of sunlight, convert these compounds into glucose and oxygen.

Which factors affect the rate of photosynthesis and how?

Factors that affect the rate of photosynthesis include light intensity, carbon dioxide levels, and temperature. Higher light intensity usually leads to faster photosynthesis, as does higher carbon dioxide levels. However, extremely high temperatures can inhibit the process as they can damage the enzymes involved.

How can a tree like the Japanese Maple that has red leaves all year long perform photosynthesis?

It sometimes may have green leaves, or it is totally dependant on minerals from soil!

well, no

If you look at any leaf, they all have pigaments, which is the leafs color.

In biology the other day we performed an experiment called plant pigments. We smushed the leaf on a line that we drew on a peace of filtered paper. Then we put this peace of paper in rubbing alchol. The alchol was at the bottom not touching the leaf yet. Slowly the alchol moved up the flitered paper, the filtered paper was absorbing it. As it did this it pulled the plants pigaments out of the plant. On the line was still red, dark blue. Then farther up was, first, light yellow, yellow, yellow-green, then green. this showed all the pigaments we did this with a green and a red leaf, the same thing happened for both, showing that both leaves have chlorophyll.

In conclusion both red and green leafs have the same pigaments, which help it carry on photosynthesis.

What is the last step of the Calvin cycle?

The last step of the Calvin cycle is regeneration of RuBP (Ribulose-1,5-bisphosphate) using ATP to continue the cycle. This is necessary to replenish the RuBP molecules that are used in the initial carbon fixation step.

Chlorophyll looks like this?

Because the chloroplasts that make chlorophyll are green.

What does a deer give off that would help a plant during photosynthesis?

Deer give off carbon dioxide when they exhale, which can be used by plants in photosynthesis to produce oxygen and sugars.

The alternative pathways of photosynthesis using the C4 or CAM systems are said to be compromises Why?

The C4 and CAM systems are considered compromises because they have evolved in response to specific environmental conditions to enhance photosynthetic efficiency by minimizing water loss and optimizing carbon fixation in suboptimal conditions such as high temperatures or low water availability. While these pathways are more energy-intensive for the plant compared to the traditional C3 pathway, they allow plants to thrive in environments where C3 photosynthesis would be less efficient.

Organic compounds that can be made from the products of the Calvin cycle include what?

Organic compounds such as glucose, starch, sucrose, and cellulose can be made from the products of the Calvin cycle. These compounds are essential for plant growth and serve as energy sources and structural components in plants.

What step of photosynthesis is glucose produced?

Glucose is produced during the Calvin cycle, which is also known as the light-independent reactions of photosynthesis. This process takes place in the stroma of the chloroplasts and requires ATP and NADPH generated during the light-dependent reactions.

One of the two parts of photosynthesis?

One of the two parts of photosynthesis is the light-dependent reactions, which occur in the thylakoid membranes of chloroplasts. These reactions use light energy to split water molecules and produce ATP and NADPH.

How much of solar energy that falls on the leaves of a plant is converted to chemical energy by photosynthesis?

On average, plants are able to convert about 1-2% of the solar energy that falls on their leaves into chemical energy through photosynthesis. The efficiency can vary depending on factors such as the type of plant, environmental conditions, and available resources.

How are carbohydrates used in cellular respiration?

Carbohydrates are broken down into glucose, which is then used in cellular respiration to produce ATP (energy) for the cell. During cellular respiration, glucose is oxidized in a series of reactions to generate ATP through the processes of glycolysis, the citric acid cycle, and the electron transport chain.

Where is photosynthesis occur?

Most photosynthesis happens in leaves. But other parts of plants above the ground can photosynthesize too. Chlorophyll is an extremely important substance, without it photosynthesis could not happen. It absorbs sunlight which makes carbon dioxide and water react together hence making glucose.

What is photosynthesis what is the eqution for photosynthesis?

Photosynthesis is the process where by green plants prepare their own food with THE aid of carbon dioxide, sunlight ,water.this will lead to the production of oxygen and glucose(simple sugar).

Equation: 12H2O (Water) + 6CO2 (Carbon Dioxide) + Light Energy = 6O2 (Oxygen) + 6H2O (water) + C6H12O6 (Glucose)

What are the dark reactions of photosynethesis also known as?

The dark reactions of photosynthesis are also known as the Calvin cycle or the light-independent reactions. These reactions take place in the stroma of chloroplasts and involve the conversion of carbon dioxide into glucose using ATP and NADPH produced during the light-dependent reactions.

Which molecule represents the end product of the Calvin cycle?

The end product of the Calvin cycle is glyceraldehyde-3-phosphate (G3P), which is a three-carbon sugar molecule. It can then be used to synthesize glucose and other carbohydrates for plant growth and energy storage.

What are the names of the sacs where photosynthesis takes place?

Photosynthesis takes place in structures called chloroplasts, which contain sac-like structures called thylakoids. Thylakoids are arranged in stacks called grana, where the light-dependent reactions of photosynthesis occur.

Is Photosynthesis food production in organisms with chlorophyll?

No, photosynthesis is a process through which plants and some other organisms convert light energy into chemical energy in the form of glucose. This glucose can later be used as a source of energy, but it is not considered food production within the organism itself.

What is the important molecule of photosynthesis?

The important molecule of photosynthesis is chlorophyll, a pigment in plant cells that captures sunlight and converts it into chemical energy through a series of reactions. Chlorophyll is essential for photosynthesis to occur and is responsible for giving plants their green color.

Where in the cell does cellular respiration and photosynthesis?

They use both but under different circumstances. During the day, they use photosynthesis. During the night, since there is no sunlight, they have to use cellular respiration to produce energy.
