Which one of the following is true for photosynthesis?
Photosynthesis requires chlorophyll, and a few other raw materials.
What is true about the products of photosynthesis?
In photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced.
Which of the following best describes photosynthesis?
Which of the following best describes photosynthesis? Photosynthesis converts radiant energy into chemical energy, Plants need sunlight, carbon dioxide, water, nutrients, and chlorophyll to complete photosynthesis, Photosynthesis produces carbohydrates.
What is photosynthesis very short answer?
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
What is photosynthesis and explain?
Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the “fuel” used by all living things.
What is importance of photosynthesis?
Answer Expert Verified It is the ultimate source of Oxygen and energy for all living organisms. 2. Photosynthesis provides food for all living beings. The process of photosynthesis occurs in green plants which are the primary producers in a food chain.
What are 2 benefits of photosynthesis?
Reasons Why Photosynthesis Is Important It is the number one source of oxygen in the atmosphere. It contributes to the carbon cycle between the earth, the oceans, plants and animals. It contributes to the symbiotic relationship between plants, humans and animals.
What are the 4 factors that affect photosynthesis?
Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.
What is the site of photosynthesis?
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
What are the three main steps of photosynthesis?
The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.
What are the 3 types of photosynthesis?
The three main types of photosynthesis are C3, C4, and CAM (crassulacean acid metabolism).
What three things are used to make glucose in photosynthesis?
Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms.
What are 3 some sources of CO2?
Three sources of CO2 is sunlight glucose (sugar) and oxygen.
What is glucose used for in photosynthesis?
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
Why is glucose important in photosynthesis?
Glucose provides plants with needed food through a process called photosynthesis. This process helps plants convert the energy they take in from sunlight into sugar to help nourish the plant. Photosynthesis occurs when carbon dioxide, water and sunlight are combined. Plants use these to form glucose and oxygen.
What are the 5 uses of glucose in plants?
5 main uses of glucose.
- RESPIRATION. This chemical reaction releases energy which allows them to convert the rest of the glucose into other useful substances which they can use to build new cells and grow.
- SEEDS. Glucose is turned into lipids (fats & oils) for storing in seeds.
- PROTEIN SYNTHESIS.
Where is glucose in photosynthesis?
What happens to glucose in plants?
Photosynthesis is the process by which plants use light energy to convert carbon dioxide and water into sugars. Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.
What are the three uses of glucose in a plant?
WHAT DO PLANTS USE GLUCOSE FOR? RESPIRATION, MAKING FRUITS, MAKING CELL WALLS, MAKING PROTEINS, STORED IN SEEDS AND STORED AS STARCH. PLANTS MAKE GLUCOSE IN THEIR LEAVES AND THEY USE SOME OF IT FOR RESPIRATION.
Why do plants store glucose?
Explanation: Plants store glucose in their leaves. They make sugar during the proccess of photosynthesis,so when they are making sugar/glucose (energy) from the sun they store some of it as a starch. I hope this helps you!
How do plants produce glucose?
Plants, unlike animals, can make their own food. They do this using a process called photosynthesis . During photosynthesis, plants produce glucose from simple inorganic molecules – carbon dioxide and water – using light energy.
Why do plants convert starch glucose?
Glucose is soluble. Starch is insoluble in water so won’t affect the way water moves in and out of the plant, meaning plants can store large amounts of starch in their cells. Starch molecules are very large so they cannot move out of the cell.
Where do plants store their glucose?
Why Glucose is not stored in our body?
Glucose is not stored in body as such because: 1. glucose is soluble in water and if it is stored as glucose it will disturb the osmotic pressure (hypertonic) that will cause the cell to lyse. Thus glucose is stored in polymeric form i.e., glycogen.
Is glycogen found in plants?
Glycogen: Glycogen is the storage form of glucose in animals and humans which is analogous to the starch in plants. Glycogen is synthesized and stored mainly in the liver and the muscles. It is found in the sap of plants, and is found in the human bloodstream where it is referred to as “blood sugar”.
Is starch a polymer?
Starch is a polysaccharide comprising glucose monomers joined in α 1,4 linkages. The simplest form of starch is the linear polymer amylose; amylopectin is the branched form. Wheat starch granules stained with iodine.
Is starch found in plant cells?
Starch is synthesized in the plastids—chloroplasts in leaves or specialized amyloplasts in the starch-storing tissues of staple crops.
What is the role of starch in plants?
Plants have to produce starch to store energy for cell metabolism. When a human eats starchy plant material, some of the starch breaks down into glucose for energy: any unused remnant of this ingested energy is stored as fat deposits.
Why is starch stored in plants instead of glucose?
Starch is better than glucose for storage because it is insoluble. Both glucose and starch can be converted into other substances. These can then be used for energy, growth and other storage products. A plant also produces oxygen as a waste product of photosynthesis.
