Photosynthesis

The stacks of thylakoids found inside chloroplasts are called grana. Grana are interconnected by stroma thylakoids and contain the pigment chlorophyll, which is essential for photosynthesis to occur efficiently.

granum are stacks of thylakoids.

grana are several stacks of thylakoids. :)

Phloem is responsible for transporting organic nutrients (such as sugars) from the leaves to other parts of the plant, while xylem is responsible for transporting water and minerals from the roots to the rest of the plant. They are vascular tissues found in plants that play crucial roles in nutrient transport and structural support.

Cellular respiration begins with the transportation of glycolysis into the mitochondria. The final step of cellular respiration will either be fermentation or an electron transport chain depending on whether it is anaerobic or aerobic respiration.

The molecule involved in the process of photosynthesis is known as glucose. Glucose is produced by plants through photosynthesis, which involves converting carbon dioxide, water, and sunlight into energy-rich sugars.

No, photosynthesis does not take place in the mitochondria. Photosynthesis occurs in the chloroplasts of plant cells, where it converts sunlight into energy in the form of glucose. Mitochondria are responsible for cellular respiration, where glucose is broken down to produce energy in the form of ATP.

The final product of the Calvin cycle that can be used as food is glucose. Glucose is a simple sugar that plants produce during photosynthesis. It serves as a source of energy for the plant and can also be used as food by animals and humans.

Energy flows through an ecosystem in one direction, which is called the food chain. It's like a pyramid. At the bottom are producers. The producers contain the most energy gotten from the sun. The next are primary consumers. Consumers obtain energy by eating the producers The next layer are the secondary consumers. There may be another layer of consumers if there is enough energy in the system.

Sunlight --> producers (100% of the energy) --> primary consumers (10%)---> secondary consumers (1%)

The decomposers return some nutrients to the system are are active at all levels.

As you move up each level the energy decreases.

For example:

Kcal = Kilocalorie (energy) For example:

Grass, a producer produces 1,000 Kcal

The grass is eaten by mice or rats, the primary consumer and gets 100 Kcal

The mice or rat are eaten by ferrets, the secondary consumer and gets has 10 Kcal.

The ferrets are then eaten by owls, the apex consumer gets 1 Kcal which may not be enough to support the owls.

It can not go any further.

In an ecosystem the energy flow depends on the 10% law.That is when energy is being transferred from producers to consumers and from consumers to herbivores carnivores ,etc. only 10 %energy stored in the previous level is taken and used by the next Trophic Level.

energy flow (E) can be defined as the sum of metabolic production (P) and respiration (R), such that E=P+R.

Below is the energy flow in the ecosystem: sun - Producer - Consumer - Decomposers - Inorganic nutrient pool.

Yes, the Calvin cycle is endergonic because it uses ATP molecules rather than creates them.

One of the compounds that is a direct output of the Calvin cycle is Glyceraldehyde 3-phosphate (G3P). It is a product of the synthesis of carbon dioxide.

The thing that makes photosynthesis so important to the earth and atmosphere and mankind is what we need to find this out for b-tech science.

The full equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2. This equation represents the conversion of carbon dioxide and water into glucose and oxygen using sunlight as an energy source through the process of photosynthesis carried out by plants, algae, and some bacteria.

Photosynthesis generates ATP during the light-dependent reactions (photophosphorylation) and NADPH during the light-dependent reactions (photolysis of water and reduction of NADP+ to NADPH).

Carbon fixation takes place during the Calvin cycle, which is the second stage of photosynthesis. In this process, carbon dioxide from the atmosphere is converted into organic compounds by using the energy obtained from light-dependent reactions.

Carbon dioxide is taken in through the leaves of the plant. Energy from the sun is used to extract electrons (in the form of hydrogen ions) from water, and these are added to carbon dioxide (a reduction reaction) to form the monosacchardie glucose--C6-H12-O6.

The first stable compound produced from CO2 in the light-independent reactions of photosynthesis is called 3-phosphoglycerate (3-PGA). This compound is formed through the fixation of CO2 by the enzyme Rubisco during the Calvin cycle.

Stomata are small openings in a leaf to allow carbon dioxide to get in during the day and oxygen to get in at night. Both gases also pass out through stomata. Water vapor also passes out of stomata.

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. Cellular respiration is the process in which an organism breaks down fuel to capture energy in a usable form (ATP).

So, the two processes cannot really be compared with respect to energy storage. Photosynthesis is an anabolic process (synthesis of glucose) while respiration is the catabolism of glucose to release the chemical bond energy of the glucose into an usable form (ATP).

Plants use light energy to rearrange the atoms of carbon and water into glucose through the process of photosynthesis. This glucose serves as a source of energy and is used to build other organic molecules needed for plant growth and development.

Plants convert the energy of sunlight into chemical energy through a process called photosynthesis. This process involves transforming carbon dioxide and water into glucose (a form of chemical energy) with the help of minerals and enzymes. The glucose produced serves as a source of energy for the plant to carry out its metabolic functions.

The ocean is essential for photosynthesis as marine plants, like phytoplankton, produce a significant portion of the Earth's oxygen through this process. Without the ocean, a vital part of the global carbon cycle would be disrupted, affecting oxygen production and overall ecosystem health.

Energy from sunlight is chemically bound into carbohydrates during photosynthesis. Plants use energy from sunlight, water, and carbon dioxide to assemble carbohydrates-- molecules made out of carbon (carbo-), hydrogen (hydrates). Plants give off oxygen because water is made out of both hydrogen and oxygen, but when plants make carbohydrates, they only use the carbon part of carbon dioxide, and release the oxygen (dioxide) back into the atmosphere, allowing us to breathe.
