Chloroplast is in leaves

Chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds. Photosynthetic cyanobacteria are free-living close relatives of chloroplasts; endosymbiotic theory posits that chloroplasts and mitochondria (energy-producing organelles in eukaryotic cells) are descended from such organisms.

chloroplasts structure with the cells of plants and algae and it is on or in the leaves

chlorophyll is the correct answer of the given question

chlorophyll.........................

Chlorophyll is the rightvaswer

the green color of plants is due to presence of chlorophyll

Chlorophyll................😃😃

the answer is chlorophll option (a)

the answer is chlorophll option (a)

the green colour of plants is due to the presence of Chlorophyll. The mesophyll cells in leaves, have a large number of chloroplasts.

In addition to giving plants their green color, chlorophyll is vital for photosynthesis as it helps to channel the energy of sunlight into chemical energy. With photosynthesis, chlorophyll absorbs energy and then transforms water and carbon dioxide into oxygen and carbohydrates. The process of photosynthesis converts solar energy into a usable form for plants, and the animals that eat them, forming the foundation of some food chains.

plants have a green pigment called chlorophyll

Ahomologous organis an organ, system, or body part that shares a common ancestry in multiple organisms. This definition is found in evolutionary biology and uses the meaning of having a similar structure or origin.

Common examples of homologous structures are the bones in the forelimbs of various vertebrates, such as humans, dogs, birds and whales. Even though the functions of these limbs are different (a human hand is for grasping, a dog's foot is for walking, a bird's wing is for flying, and a whale's flipper is for swimming), they all have similar bone structures.

AIDS is caused by virus called as HIV (Human Immunodeficiency Virus) which kills the immune cells of our body (Helper T Cells). These helper T cells are responsible for production of antibodies from B cells (Antibody producing cells) to fight different infections and pathogens. So when person is infected with HIV, his immunity to fight against different pathogens is much lowered as a result different types of viral and bacterial pathogens can invade his body and different types of diseases and infections, affecting different body parts and organs can be developed. So AIDS is not a single disease but a group of disease.That’s why it is called as syndrome.

6) Answer-Dracunculiasis, also known asGuinea worm disease(GWD), is aninfectioncaused by the parasite Dracunculus medinensis. A parasite is an organism that feeds off of another organism to survive.

type of farming in which instead of using pesticide and fertilizer we use bio-pesticide and bio-fertilizer

Organic farming is a method of crop and livestock production that involves much more than choosing not to use pesticides, fertilizers, genetically modified organisms, antibiotics and growth hormones.

Organic production is a holistic system designed to optimize the productivity and fitness of diverse communities within the agro-ecosystem, including soil organisms, plants, livestock and people. The principal goal of organic production is to develop enterprises that are sustainable and harmonious with the environment.

Advantages of organic farming. Farmers can reduce their production costs because they do not need to buyexpensivechemicals and fertilizers. In the long term , organic farms save energy and protect theenvironment. More animals and plants can live in the same place in a natural way.

1. Organic manures produce optimal condition in the soil for high yields and good quality crops.

2. They supply the entire nutrient required by the plant (NPK, secondary and micronutrients).

3. They improve plant growth and physiological activities of plants.

4. They improve the soil physical properties such as granulation and good tilt, good giving good aeration easy rot penetration and improved water holding capacity.

5. They improve the soil chemical properties such as supply and retention of soil nutrient and promote favorable chemical reaction.

6. They reduce the need for purchased inputs.

Organic farming is a technique which involves cultivation of plants and animals and rearing of animals in natural ways. Benefits: Reduces the level of pollutionReduces the level of residues

Microorganismplays veryimportant roleinagriculturebecause thesoil microbes(bacteriaand fungi) are essential for decomposingorganicmatter and recycling old plant material. Somesoil bacteriaand fungi form relationships with plant roots that provideimportantnutrients like nitrogen or phosphorus. Especially in organic farming where no chemical fertilizer is used,there microbes prove to be very useful.

Food processing is the transformation of agricultural products into food, or of one form of food into other forms. Food processing includes many forms of processing foods, from grinding grain to make raw flour to home cooking to complex industrial methods used to make convenience foods.The food items that are grown by the methods oforganic farmingare tastier and healthier. The mostimportantnutrients that humans get from fruits, vegetable and other food items are – calcium, protein, carbohydrates, vitamins etc.Organic farmingpreserves the nutrients of the food item, which makes us healthier.

Ans :- E waste known as electronic waste is all that electronic items which needs to be cleared.

Such as computing devices such as tablets, iPods, PCs, laptops, televisions and all home appliances.

Recent years as technology continued to develop the amount of e-waste produced has also doubled up. Electronic waste is a common name for electronic products moving towards end of their useful life.

As gasoline and diesel prices increase, the need for a cleaner and less expensive alternative fuel (cng tanks) becomes even more important. Today, there are several kinds of alternative fuels available to us. New technologies that will power the cars of the future are being developed. However some of these technologies are still in its infancy and are not yet readily available. More and more people all over the world are also looking for an alternative fuel. And among the many options available, compressed natural gas or CNG appears to be the viable option. But the question that needs to be answered is whether CNG is indeed a better fuel and why.

Here are the advantages CNG has over petroleum-based fuels such as gasoline.

Compressed natural gas is a clean-burning fuel. It is actually the cleanest of all fossil fuels. Since natural gas is composed mainly of methane, burning it produces carbon dioxide and water vapor. These are the same compounds we exhale when we breathe. Meanwhile, petroleum produces higher carbon emissions, nitrogen oxides and sulfur dioxide. Burning fuel oil also produces ash particulates that worsen pollution.

Combustion of natural gas releases very small amounts of these compounds. For instance, carbon monoxide emission is reduced by about 80% in CNG-powered cars compared to gasoline-powered vehicles. CNG also produces 45% less hydrocarbons than gasoline. And although natural gas also produces greenhouse gases, it is considerably reduced compared to gasoline or diesel. This helps reduce the harmful effects of greenhouse gases to the environment particularly through global warming.

A Mendelian experiment consisted of breeding tall pea plants bearing violet flowers with short pea plants bearing white flowers.The progeny all bore violet flowers ,but almost half of them were short . This suggests that the genetic make up of the tall parent can be depicted as

According to law of inheritance, the dominant character appears in the F1 project. Among violet flowers and white flowers, the character of violet character is dominant. So, all the flowers in F1 progeny will be violet

TtWW for 50% tall the parent genotype must be Tt becz if it TT then all plant are tall ......for voilet colour it must be WW becz if it is Ww it the only 50% has voilet colour

According to law of inheritance, the dominant character appears in the F1 project. Among violet flowers and white flowers, the character of violet character is dominant. So, all the flowers in F1 progeny will be violet.

The progeny all bore violet flowers ,but almost half of them were short . This suggests that the genetic make up of the tall parent can be depicted as : a. TtWw or b. TtWW.

TtWW for 50% tall the parent genotype must be Tt becz if it TT then all plant are tall ......for voilet colour it must be WW becz if it is Ww it the only 50% has voilet colour ....

Hence,According to law of inheritance, the dominant character appears in the F1 project. Among violet flowers and white flowers, the character of violet character is dominant. So, all the flowers in F1 progeny will be violet.

A Mendelian’s experiment consists of breeding a pea plant bearing violet flowers with pea plant that bear white flowers.

The intermediate colours do not get a chance to appear in the offspring of cross-pollinated pea plants.

The result in f1 progeny will be violet flower because it is dominant over the white flower.
