Chloroplasts is prokaryoty or euroryote?

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

Why are there few blue-colored plants?

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.

What does CO2 do to sugar?

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.

If you wanted to increase the rate of photosynthesis in a plan you would develop a plant with what?

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.

How does water form during cellular resperation?

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.

The food conducting tissue of a plant is xylem why or is it correct?

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.

How is food prepared in Plants during Photosynthesis?

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.

Energy is pass around chlorophyll molecules until it reaches a specific chlorophyll molecule called?

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.

How do the organisms perform photosynthesis?

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.

A plant exposed to light are carrying out photosynthesis which means that they are producing oxygen while they consume carbon dioxide what will happen over time when the plant is sealed in the jar?

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.

How does oxygen enter the leaf?

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.

Which part of the plant absorbs minerals for photosynthesis?

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.

Which chemical compound absorbs CO2 during photosynthesis?

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.

Why can egg cells from a horse only contain an x chromosomes?

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.

What is the name of plant which doesn't have leaves?

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.

What structure in leaves allows the gaseous reactants and products of photosynthesis to move in and out?

Stomata are the small pores found mainly on the underside of leaves that allow for the exchange of gases like carbon dioxide and oxygen during photosynthesis. These openings can open and close to regulate the passage of gases and water vapor.

What form of energy do plants need and where do they get it from?

Plants are able to capture light energy using chlorophyll in the process of photosynthesis.

How are photosynthesis and cellular respiration reciprocal reactions?

Photosynthesis and cellular respiration are reciprocal reactions because they have opposite chemical equations. Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen, while cellular respiration breaks down glucose into carbon dioxide and water, releasing energy. The products of one process are the reactants of the other, creating a continuous cycle in nature.

One of the important waste products of photosynthesis is oxygen gas Where does this oxygen gas come from?

Oxygen gas produced during photosynthesis comes from the splitting of water molecules (H2O) into oxygen (O2) and hydrogen ions (H+). This process, known as photolysis, occurs in the light-dependent reactions of photosynthesis.

How are plant cells related to photosynthesis?

Plant cells are the site where photosynthesis occurs. Within plant cells, chloroplasts contain chlorophyll, a pigment that absorbs light energy to drive the photosynthesis process. Through photosynthesis, plant cells convert light energy, carbon dioxide, and water into glucose and oxygen, which serves as an energy source for the plant.

What are the duties of a raw materials coordinator?

A raw materials coordinator is responsible for overseeing the procurement, inventory management, and delivery of raw materials needed for production. They work closely with suppliers to ensure timely and cost-effective sourcing of materials, monitor inventory levels to prevent shortages, and coordinate with production teams to ensure seamless supply chain operations. Additionally, they may be involved in quality control checks to ensure that raw materials meet specified standards.

What is the importance of green plants as food producers?

The green plants perform photosynthesis and thus produce organic compounds like glucose from inorganic compounds like H2O and CO2 in their chloroplasts in the presence of light. All other food products are derivatives of photosynthetic products.

A plant that produces its own food?

Plants that produce their own food through photosynthesis are called autotrophs. They use light energy to convert carbon dioxide and water into glucose, a process that requires chlorophyll pigment found in their chloroplasts. This ability to self-sustain and create energy from inorganic sources is a defining characteristic of plants.
