Photosynthesis – Old Year Questions

• Chlorophyll is made up of carbon, hydrogen, oxygen, nitrogen and magnesium, but calcium is not part of it.

• Chlorophyll in green plants needs magnesium to work and help with photosynthesis. During photosynthesis, light is used to make electrons move around in the molecules.
• If there is not enough magnesium, the leaves of the plants can turn yellow between the veins.

• Chlorophyll, found in green plants, needs magnesium to be produced.
• During photosynthesis, light is absorbed by the chlorophyll which then triggers electrons to move to other molecules.
• If the plants don’t have enough magnesium, the leaves will turn yellow in between the veins.

• Photosynthesis happens inside parts of the cell called chloroplasts. The main result of photosynthesis is glucose, which is a molecule used to give energy to the cell. Oxygen is made as a side effect of photosynthesis.

• Photosynthesis is the process of converting light energy tochemical energy and storing it in the bonds of sugar. In thisprocess, carbon dioxide (CO2) is taken in from the atmosphereand oxygen (O2) is released out during the formation of glucose (C6H12O6).

• Photosynthesis produces oxygen gas, which comes from water and not from carbon dioxide. During photosynthesis, water molecules are split to create oxygen.

• Plants absorb sunlight, which then causes the water molecules to break apart into hydrogen ions and oxygen gas, a process called photolysis.

• Most of the photosynthesis that happens on earth is done by water plants and algae. Of this, 85% happens in the ocean (mainly by algae) and 5% happens in rivers, ponds, etc.
• Photosynthesis is the process of taking in carbon dioxide and producing oxygen and carbohydrates.

• Green plants are able to produce their own food from basic substances (CO2 and H2O) in the presence of light.
• They usually use the sun’s light (during the day), but some marine algae can also use moonlight. Photosynthesis can even happen under electric light.

• Plants can make their own food from basic elements (carbon dioxide and water) when exposed to light.
• They usually rely on the sun during the day, but some sea algae can also use moonlight. Photosynthesis is also possible under artificial lighting.

• Plants can create their own food from carbon dioxide and water when they have light. Usually, the sun is used for this, but some sea algae can also use moonlight.
• It is possible for plants to do photosynthesis even with artificial light.

• Photosynthesis mainly happens in leaves, and a bit in stems. Special cells called chloroplasts are used for photosynthesis.
• Leaves have two parts, a petiole (stalk) and lamina (flat part). The lamina has a large surface area which helps with absorbing sunlight and carbon dioxide.
• Chlorophyll in the chloroplasts absorbs light from the sun. The stomata (tiny pores) allows carbon dioxide to enter and oxygen to leave the plant.

• Plants use certain colors of light for photosynthesis. The chlorophyll absorbs blue, red, and violet light. These colors help the photosynthesis process, while green light does not.

• Photosynthesis only happens when visible light between 3800 and 7600 wavelengths is present.
• Red light is best for photosynthesis, followed by blue light, while green light has no effect.
• In 1888, Englemann did an experiment where he showed that more oxygen was produced by algae with red light and the most aerobic bacteria was accumulated in this light.
• When using blue light, fewer bacteria was accumulated.

• Photosynthesis is what plants do to turn light energy into chemical energy. It is shown by a chemical equation.

Where CO2 = Carbon dioxide
H2O = Water
C6 H12O6= Glucose
O2 = Oxygen

• In photosynthesis, 18 molecules of A.T.P., 6 molecules of CO2, and 12 molecules of NADPH are all used to make one molecule of Glucose.

• In photosynthesis, sunlight is changed into energy stored in ATP and NADPH inside the chloroplasts.
• This process of converting energy from sunlight to chemical energy is called the light reaction.

• In photosynthesis, the energy from the sun is changed into ATP in the chloroplast. During the light reactions, the energy from the sun is changed into chemical energy that is stored in two molecules, ATP and NADPH.

• In photosynthesis, the energy from the sun is changed into ATP in the chloroplast. During the light reactions, the energy from the sun is changed into chemical energy that is stored in two molecules, ATP and NADPH.

• In photosynthesis, light energy is turned into a form of potential energy called chemical energy. This energy is stored in the bonds between atoms and molecules.

• Sunlight is the main energy source on Earth. Through photosynthesis, this energy is changed into a chemical form that both photosynthetic and non-photosynthetic organisms can use.
• Photosynthesis is the process of transforming sunlight into a chemical form of energy, which is then used in all life on Earth.

• Chlorella is a type of single-celled green algae. It is thought to be a possible food and energy source.
• Out of the available options, Chlorella has the greatest ability to turn sunlight into chemical energy through photosynthesis.

• Leaves in plants absorb light, carbon dioxide, and water to make food. Roots do not have chloroplasts, so they cannot do photosynthesis.

• Carbon dioxide is a very important gas in the atmosphere. It helps keep the environment warm by trapping heat, helps rocks break down, and is a carbon source for plants.
• It is stored in living things, organic matter and rocks like limestone. It comes from the earth’s interior, decay of organic matter, volcanoes, and volcanoes around where two plates meet.
• Photosynthesis takes CO2 from the air and replaces it with oxygen, while respiration takes oxygen from the air and replaces it with CO2.

• It’s not a good idea to sleep under a tree at night because the tree breathes out carbon dioxide, which is not replaced with oxygen.
• This happens because photosynthesis, which turns CO2 to oxygen, only works when there is light. So, if we sleep under a big tree at night, there won’t be enough oxygen for us to breathe.

• Bacteria that live in the deep sea, like green sulphur bacteria, use infrared light to make energy through photosynthesis.
