What compounds do plants use to make glucose molecules and where do they get it from?

Plants use carbon dioxide and water to make glucose molecules through the process of photosynthesis. Carbon dioxide is taken in from the atmosphere through tiny pores in the leaves called stomata, and water is absorbed from the soil through the plant's roots. These compounds are converted into glucose with the help of sunlight and chlorophyll.

Can a plant such as a mushroom manufacture glucose by the process of photosynthesis?

No, mushrooms cannot perform photosynthesis as they do not have chlorophyll, the pigment needed to convert sunlight into glucose. Instead, mushrooms obtain nutrients by breaking down organic matter through a process called decomposition.

How does photosynthesis help us survive?

Photosynthesis helps us survive because it is a way for plants, grass, and trees to produce it's own food so they won't die.Plants, trees, and grass produce oxygen and breath in the carbon dioxide so we can breath in fresh air and survive.

What is the source of the carbon and oxygen that are part of the glucose made during photosynthesis?

"the equation:6 CO2(gas) + 12 H2O(liquid) + photons and Chlorophyll → C6H12O6(aqueous) + 6 O2(gas) + 6 H2O (Water )

That means = For every single molecule of Glucose six molecules of CO2 and twlwve molecules of H2O are used up as raw material . Chlorophyll and chloroplasts are used as the machinery AND Light is the source of power or energy !!

Now let us turn to your question =

where does the Oxygen and Carbon come from?

Ans = The CO2 gas that enters the leaf through the stomata is the source of Carbon in Glucose .

It is linked with H2O to form glucose .

So finally Oxygen and Carbon in glucose come from two sources CO2 & H2O "

Where are enzymes associated with light dependent reactions of photosynthesis located?

Enzymes associated with the light-dependent reactions of photosynthesis are located in the thylakoid membranes of the chloroplasts. Key enzymes involved include ATP synthase, cytochrome b6f, and the enzyme complexes involved in the photosystems (PSII and PSI). These enzymes work together to capture light energy and convert it into chemical energy in the form of ATP and NADPH.

What occurs in each stage of meiosis?

=Meiosis is a nuclear division process that divides the parental chromosome number in half. Meiosis differ from mitosis, a nuclear division mechanism. Meiosis sorts chromosomes into parcels not one but twice. Meiosis occurs only in specialized reproductive cells. Meiosis consist of two divisions: Meiosis I and Meiosis II. In meiosis I, each duplicated chromosome aligns with its partner, homologue to homologue. after they are sorted and arranged this way, each homologous chromosome is pulled away from its partner. all homologues move apart from their partners and end up in two new nuclei. when the cytoplasm divides, there are two daughter cells with one of each type of chromosome. the chromosomes are still duplicated. Then, during Meiosis II, the 2 sister chromatids of each chromosome separate. they become individual, unduplicated chromosomes. there are now four parcels of chromosomes; each contains one unduplicated chromosome of each type. new nuclear envelopes begin to enclose them as 4 nuclei inside 2 cells.==Meiosis I: Prophase I, Metaphase I, AnaphaseI, Telophase I (Interphase: DNA is replicated prior to meiosis I)==Meiosis II: Prophase II, Metaphase II, Anaphase II, Telophase II (No interphase DNA is not replicated prior to meiosis II)=

What is NADP related to biology?

NADP is an important molecule used in cellular respiration (or making energy). When a cell breaks down glucose it converts 2 NADP molecules into 2 NADPH molecules, basically a NADP molecule with an extra hydrogen attached. That hydrogen bond has energy, that when broken releases energy to do other things. Further down the chain of the Krebs Cycle and the Electron Transport Chain, NADPH's convert ADP (adenosine di-phosphate) into ATP (adenosine tri-phosphate), the main energy molecule in bacteria, animal, and plant cells.

The source of oxygen produced during photosynthesis is?

The source of oxygen produced during photosynthesis is water. During the light-dependent reactions of photosynthesis, water molecules are split into oxygen, protons, and electrons, releasing oxygen as a byproduct.

What happens during prometaphase?

=In this stage the nuclear envelope breaks down so there is no longer a recognizable nucleus. Some mitotic spindle fibers elongate from the centrosomes and attach to kinetochores, protein bundles at the centromere region on the chromosomes where sister chromatids are joined. Other spindle fibers elongate but instead of attaching to chromosomes, overlap each other at the cell center.=

In what type of cells do choloroplast take place?

Chloroplasts are found only in plant cells. They contain the green pigment called chlorophyll, which absorbs sunlight. The chloroplasts use the sunlight energy to make food (sugar) for the plant. Chloroplasts are found mainly in the leaf cells in plants. Cells in the top half of the leaf, called palisade cells, have many chloroplasts. Cells in the bottom half of the leaf, called spongy cells, have fewer chloroplasts. Not all plant cells contain chloroplasts. For example cells inside the stem, and root cells, usually lack chloroplasts. Also the 'skin' cells (epidermis) on the leaves do not contain chloropasts. For more information about chloroplasts see: http://www.biology4kids.com/files/cell_chloroplast.html

What happens to carbon dioxide during photosynthesis?

During photosynthesis, carbon dioxide is taken in by plants and converted into glucose through a series of chemical reactions. This process requires energy from sunlight and produces oxygen as a byproduct. The carbon from carbon dioxide is stored in the plant's tissues, ultimately serving as a source of energy for the plant itself or for other organisms that consume it.

In which organelle does cellular respiration take place?

Cellular respiration takes place in the mitochondria of the cell. It is a process that converts glucose and oxygen into cellular energy, ATP, water, and carbon dioxide.

How are chemosynthetic organisms and plants similar as energy?

Chemosynthetic organisms and plants both create energy through biological processes. Chemosynthetic organisms use inorganic molecules to produce energy, while plants use sunlight for photosynthesis. Both processes are the foundation of the food chain and are essential for supporting life in their respective ecosystems.

What organisms cannot make glucose from carbon dioxide and water?

Animals, including humans, cannot make glucose from carbon dioxide and water because they lack the necessary enzymes and metabolic pathways for photosynthesis. Instead, animals obtain glucose by consuming plants or other animals that have already synthesized glucose through photosynthesis.

How does photosynthesis and respiration in green plants meet the needs of the cell?

Respiration is an essential life process in plants. It is necessary for the synthesis of essential metabolites including carbohydrates, amino acids and fatty acids, as well as for the transport of minerals and other solutes between cells. It consumes between 25 and 75% of all the carbohydrates produced in photosynthesis at ordinary growth rates.

What do you do if your wife will not perform fellatio?

Speak to her calmly and politely and explain how you feel about this topic and then try your hardest not to bring it up again as if you bother and pester her about it it just becomes a major turn off as well as she won't do it if she is told to. If she really just does not like doing it and you love her please respect her and her wishes and try to find a way between the two of you to get by this.

Clusters of pigment molecules?

Clusters of pigment molecules are aggregates of pigments that come together in a specific spatial arrangement. These clusters play a key role in light absorption and energy transfer processes in photosynthetic organisms, such as plants and algae. By organizing pigment molecules in clusters, these organisms can efficiently capture light energy for photosynthesis.

How are photosynthesis and respirations are alike?

Answer: Davidmt1: They're opposites. Resperation takes in oxygen uses it to produce energy and then releases carbon dioxide. While photosynthesis draws in carbon dioxide uses it too produce energy then releases oxygen. So even though they both create energy their processes are opposites.

Photosynthesis is essential for?

life! Many different life forms depend on photosynthesis. Humans do because photosynthesis processes the Carbon Dioxide we exhale, and give our Oxygen for us to inhale. Too much Carbon DIoxide is harmful to humans and animals alike, and if we didnt have oxygen, well it should be a given, but we would die. The Ozone layer would be pretty messed up too. Plant life depends on it since photosynthesis processes RuDP, also known as glucose, a 6 carbon sugar. this is nessesary in producing complex carbohydrates such as starch. Animals depend on photosynthesis since some are vegitarian. Those who are vegitarian would die since the plants would die off. The others who werent would die off anyways since there were no vegitarian animals to feed off of. So basically the entire food chain would get messed up. Then there would pretty much be nothing left on earth. except maybe fungi eating up all the dead bodies... but idk. so,

What kind of a molecule is the end product of the Calvin cycle?

The end product of the Calvin cycle is a three-carbon sugar molecule called glyceraldehyde-3-phosphate (G3P). This molecule can be used to produce glucose and other carbohydrates, which serve as a source of energy for the plant.

What major and accessory pigments are necessary for photosynthesis to be carried out?

Chlorophylls (a, b, c, and d. However, their presence depends on the type of organism); carotenoids and phycobilins are accessory pigments. the pigment necessary for photosynthesis is called chlorophyll, which traps the energy in sunlight. it is present in chloroplasts, which are small disc-shaped structures present in a plant cell.
