Photosynthesis

Plant cells use carbon dioxide and water to make glucose through the process of photosynthesis, which is catalyzed by enzymes and chlorophyll.

To prepare a project on apical dominance, consider researching the factors influencing apical dominance, its importance in plant growth and development, and its practical applications in agriculture and horticulture. Include diagrams or illustrations to explain key concepts, and consider conducting experiments or observations to demonstrate apical dominance in action. Conclude with a summary of the project findings and implications for future research or agricultural practices.

No. There are only certain wavelengths of light that plants can use for photosynthesis.


Plants have trouble using green light because it is reflected by the chlorophyll pigment (that is why leaves look green).

False. During photosynthesis, electrons are typically carried by molecules such as chlorophyll and other electron carriers like NADPH, which is a reduced form of NADP+. Hydrogen ions do play a role in some reactions during photosynthesis, but they are not primarily responsible for transferring electrons between molecules.

False. In cellular respiration, glycolysis occurs before the Krebs cycle. Glycolysis is the first step in breaking down glucose to produce energy. The Krebs cycle follows glycolysis in the process of cellular respiration.

The pigment responsible for the purple color in a Rhoeo leaf is anthocyanin. Anthocyanin is a water-soluble pigment commonly found in plants that appear red, blue, or purple in color.

Yes, carotenes play a role in capturing sunlight during photosynthesis. They are pigments that absorb light energy and transfer it to chlorophyll, which is the primary pigment responsible for photosynthesis in plants. Carotenes absorb light in the blue and green regions of the spectrum and broaden the range of light that can be used for photosynthesis.

No, respiration does not use sunlight as its energy source. Respiration is a process in which cells break down glucose to release energy. Sunlight is used in photosynthesis by plants to produce glucose, which is then used in respiration.

Chloroplast cant be classified as a cell, but some research says that it may have been prokaryotic ages ago, as with mitochondria.

Plants generally appear green due to chlorophyll, the pigment responsible for photosynthesis. Blue pigmentation in plants is less common because it absorbs less light for photosynthesis compared to green pigments. Also, blue light is less prevalent in the natural environment, so blue pigments may offer less of an advantage for plant survival.

CO2 reacts with sugar in a process called fermentation, where it converts sugar into alcohol and carbon dioxide. This reaction is commonly used in the production of products such as bread, beer, and wine.

To increase the rate of photosynthesis in a plant, you could develop a plant with higher chlorophyll content, increased surface area for light absorption, and improved CO2 uptake efficiency through enhanced stomatal function. Additionally, optimizing nutrient availability and water supply would also support higher photosynthetic rates.

During cellular respiration, water is formed as a byproduct of the electron transport chain. Oxygen acts as the final electron acceptor, leading to the formation of water molecules. This process occurs in the mitochondria of the cell.

No, the food conducting tissue of a plant is actually phloem. Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem transports sugars produced by photosynthesis from the leaves to other parts of the plant.

During photosynthesis, plants use sunlight to convert water and carbon dioxide into glucose (sugar) and oxygen. This process occurs in specialized structures called chloroplasts, where chlorophyll absorbs light energy to drive the chemical reactions responsible for producing food. The glucose produced is then used as an energy source for the plant's growth and metabolism.

Chlorophyll is arranged in clusters called photosystem. It is like a upside down cone. It is made from secondary chlorophyll pigments surrounding a reaction center(primary pigment) at the tip of the cone. The secondary pigments absorb the light energy and pass it to the reaction center.

Organisms perform photosynthesis by using chlorophyll and other pigments to capture sunlight energy. This energy is used to convert carbon dioxide and water into glucose and oxygen through a series of chemical reactions in the chloroplasts of plant cells. The glucose serves as an energy source for the organism, while the oxygen is released into the atmosphere as a byproduct.

If all the other factors are taken care of, water supply, nutrients, plant species, light intensity, and such, it is possible the plant to set up a micro environment in the jar allowing it to produce its own Co2 and O2

But if no further resource is added into the jar, then eventually the plant will wilt and die.

Oxygen moves through leafy plants through the "stoma, pleural: stomata". They are small pores in the leaf that can open and close to allow gas exchange. However, most plants exhale oxygen (O2) and inhale carbon dioxide (CO2), so oxygen is generally leaving a plant.

The roots of a plant absorb minerals from the soil, such as nitrogen, phosphorus, and potassium, which are essential for photosynthesis to occur in the leaves. Minerals are transported from the roots to the leaves through the vascular system of the plant.

CRYSTALLINE sponges pocked with pores that are just the right size to trap carbon dioxide molecules could filter the fumes from power stations and cars. What's more, the trapped CO2 can then be sucked from the crystals and piped into containers and buried underground, allowing the crystals to be reused. Carbon capture and storage has been touted as a powerful weapon against global warming. Until now, the only way to strip CO2 from car exhaust, flue gases or power-plant emissions was to bubble them through a solvent that reacts with CO2. The trouble is that subsequently removing the gas from the solvent requires heat, limiting the efficiency of the process. "Anything that has the potential to reduce this 'energy penalty' is extremely valuable," says Stuart Haszeldine, an expert on carbon capture at the University of Edinburgh, UK. So Omar Yaghi and colleagues at the University of California, Los Angeles, created powders made of porous crystals that soak up CO2. When the crystals are fully loaded, the gas can be released by a drop in pressure, which sucks the CO2 right out. Their crystals, called "zeolitic imidazolate frameworks" (ZIFs), have pores that are big enough to allow CO2 molecules inside, but small enough to retain them. The crystals are created by blending cobalt or zinc with organic molecules called imidazolates - the pore size depends on the imidazolate used. The researchers created 25 different ZIFs but only three had pores of about the right size to trap CO2. The team bubbled a mixture of CO2 and carbon monoxide (CO) gas over each of them. All three trapped CO2, with the most efficient soaking up 83 times its own volume, but little CO (Science, DOI: 10.1126/science.1152516). To bury CO2 the gas must not be contaminated by other molecules - which might be toxic and leach out - so this selectivity is key. "We're optimistic that within a year or two these materials will be ready for testing in power stations," says Rahul Banerjee, a member of the UCLA team. ZIFs should be tough enough to survive harsh conditions inside power stations, he says. In tests, they withstood temperatures of 400 °C.

Females only contain X in their sex chromosomes. That s why females have XX and males XY. When females form gametes, they only can form them with a X chromosome. This however have some exceptions, for example, chicken females are XY whereas males are the one with XX.

A plant without leaves is commonly known as a leafless plant or a leafless succulent. One example of a leafless plant is the mistletoe, which relies on its host plant for nutrients and water. Another example is the cactus, which has adapted its stems to carry out photosynthesis instead of traditional leaves.

Fungi is your answer :)

It is true. That is why Plants and Animals need each other hah
