Why don't plants use UV rays for photosynthesis?

because the ozone in the earth's atmosphere absorbs most UV wavelengths, plants have evolved accordingly. while most pigments developed don't use UV light, some wavelengths are still converted into energy.

What are the different indigenous raw materials that can be used for handicraft?

Indigenous raw materials for handicrafts can include natural fibers like cotton, hemp, or sisal, as well as materials like wood, clay, beads, shells, and feathers. These materials are often sourced locally and reflect the cultural traditions and resources of the indigenous communities.

What molecule controls the reaction rate of photosynthesis and cellular respiration?

Isolated pea chloroplasts undergo both cyclic and non-cyclic electron flow. Both processes are coupled to photophosphorylation. During non-cyclic flow the rate of oxygen production showed ADP-governed `photosynthetic control' analogous to respiratory control of isolated mitochondria. Measurements of ADP/O and photosynthetic control ratios yielded values of 1-1·3 and 2-5·7 respectively. `Photosynthetic control' was shown to be dependent on the intactness of the chloroplasts.

What is a 69ner?

a 69er is a very famous sexual position perfored by the great pornstar Lucy Pinder

Photosynthetic protists with boxlike double shells are?

Diatoms are photosynthetic protists with boxlike double shells known as frustules. These frustules are made of silica and provide diatoms with protection and structural support. Diatoms are an important component of aquatic ecosystems and play a significant role in the global carbon cycle.

Herbaceous and young woody stems carry on photosynthesis in the cells of the a.xylem b. cortex c.phloem d.vascular cambium?

Herbaceous and young woody stems conduct photosynthesis in the cells of the cortex, a tissue located just beneath the epidermis. The xylem is responsible for transporting water and minerals, while the phloem is involved in the transport of sugars produced during photosynthesis. The vascular cambium is a region of meristematic tissue that gives rise to secondary xylem and phloem in woody plants.

Does respiration or photosynthesis make water?

Yes. When you breath out you breath out moisture and that is water.

Oxygen is the last electron acceptor .When it accepts water is produced

What are the key terms for photosynthesis?

The words you can get are: * photo * synthesis * thesis * the * ten * sin * sine * then * yes * toe(s) * toy(s) * hot * top * is * sis * nose * no * to * too * this * this * sit * site * net(s) * set Those are all i can see at this moment ____________________________________________________

What is the equation formula for photosynthesis?

6CO2 + 6H2O ------> C6H12O6 + 6O2

CO2 = carbon dioxide

H2O = water

C6H12O6 = glucose

O2 = oxygen

Light energy is required

What is the overall photosynthesis reaction?

Overall the effect of photosynthesis is when plants take in the energy from sunlight created by the sun to make sugars that the plant use for food. All of this recycles through the nitrogen, carbon dioxide, food chains or food webs, and life cycle of all plants, animals or other living organisms. Plants are producers and the process of photosynthesis makes them the bottom of the fod pyramid. Other organisms depend on the main source of energy, which is the plants.

Which one of the following events occur during Calvin cycle reactions?

For a person to know which of the following events occurs during the Calvin cycle reactions they need to know what the events are. If the events are not listed they will not know which will be the answer.

How is NADPH and ATP recycled throughout photosynthesis?

During photosynthesis, NADPH and ATP are recycled through the light-dependent reactions. NADPH is regenerated through the reduction of NADP+ by electrons from water in the electron transport chain. ATP is regenerated through the phosphorylation of ADP using energy from electron transport chain.

Is oxygen neccessary for photosynthesis?

Yes, oxygen is necessary for photosynthesis because it is produced as a byproduct of the process. During photosynthesis, plants and other organisms use carbon dioxide and water to produce glucose and oxygen through the action of sunlight and chlorophyll.

How does photosynthesis and respiration use active transport?

Both processes use active transport to move molecules across cellular membranes against their concentration gradient. In photosynthesis, active transport is used to move ions across the thylakoid membrane to create a proton gradient for ATP production. In respiration, active transport is involved in pumping hydrogen ions across the inner mitochondrial membrane to generate ATP through oxidative phosphorylation.

Do girls perform cunnilingus?

Well she would be a lesbian so I'd suggest making sure the other girl was clean and washed down there or maybe shaved as to make it more smoothe it's very enjoyable :)

Where are the raw materials of GHD straighteners from?

The raw materials of GHD straighteners are sourced from various suppliers worldwide, depending on the specific components. Some common raw materials used include plastic, aluminum, ceramic, and electrical components such as wiring and heating elements.

Why is there chlorophyll in photosynthesis?

Chlorophyll is necessary in photosynthesis, because:

1. it absorbs the light necessary for photosynthesis mostly the blue and red light but poorly in green light because of electromagnetic spectrm

2. gives the leaves it green color

Why is the waste gas the green plants give off during photosynthesis important to us?

The waste gas released by green plants during photosynthesis is oxygen, which is crucial for the survival of most living organisms, including humans. We rely on plants to produce oxygen through photosynthesis, which we breathe in to support our respiration and overall metabolic processes.

What is the reaction that complex the part of a photosystem that donates excited electrons?

The reaction involves the transfer of excited electrons from chlorophyll to a nearby primary electron acceptor molecule. This process is vital in photosynthesis as it initiates the flow of electrons through the electron transport chain.

What does clorophyll have to do with photosynthesis?

Chlorophyll is a pigment in plants that absorbs light energy for photosynthesis. It is responsible for capturing sunlight and converting it into chemical energy used to produce glucose from carbon dioxide and water. In this process, chlorophyll plays a critical role in enabling plants to make their own food.

What is the relationship between early photosynthetic autotrophs and the eventual rise of aerobic life forms?

Early photosynthetic autotrophs, such as cyanobacteria, played a crucial role in the rise of aerobic life forms by producing oxygen as a byproduct of photosynthesis. This oxygen eventually accumulated in the atmosphere, leading to the development of aerobic respiration in organisms, which enabled more efficient energy production. This shift towards aerobic metabolism allowed for the diversification and expansion of life forms on Earth.

What are the three components needed in photosynthesis?

The three required components are:

Reactants : carbon dioxide and water'

Catalyst : chlorophyll

Energy Source: sunlight

When the reactants are acted upon in the chloroplast of a leaf, the energy from sunlight is stored as molecular bonds in hydrocarbon (carbohydrate) molecules, and free oxygen is released.

Are there plants that don't use photosynthesis?

Almost all living things that are classified as plants carry out photosynthesis.

However, a very few plants do not. For example, the Indian pipe plant, Monotropa uniflora, contains no chlorophyll. Instead, the Indian pipe takes nutrients from a fungus. Indian pipes grow in areas of low light that tend to be rich in decaying plant matter. As a result, they have adapted to obtain nutrients from the fungi that digest the decaying pant matter.

This method of obtaining nutrients is a form of parasitism called myco-heterotrophy. There are several types of plants that live in similar low light conditions that have adapted to obtain nutrients in this way, including non-photosynthetic orchids and non-photosynthetic liverworts.

Why do plants need magnesium?

Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis.

Magnesium is found in algal pigments (known as chlorophyll) and is used in the metabolism of plants, algae, fungi, and bacteria.

Magnesium is found in many enzymes in both plantsand animals. An enzyme is a catalyst in a living organism. It speeds up the rate at which certain changes

Without magnesium it would die because it would not be able to photosynthesise. So it would not have any food which is glucose as energy for growth and repair. The magnesium is needed so that the chlorophyll in the chloroplasts can capture the sun's light energy and use it for photosynthesis.

(Cheers)

What are reactions of photosynthesis that do not use sunlight and make glucose?

The reactions of photosynthesis that do not require sunlight are the Calvin cycle (light-independent reactions). In this cycle, carbon dioxide is converted into glucose using ATP and NADPH generated during the light-dependent reactions. This process occurs in the stroma of the chloroplast.
