Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What converts light energy to chemical energy in plants?
Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.
What is the process called by which plants turn light energy into chemical energy in which organelle does this process occur?
Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars).
What is it called when plants turn sunlight into energy?
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 occurs in the process of photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen . ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
Which step in photosynthesis does not need light?
The light-independent stage, also known as the Calvin Cycle , takes place in the stroma, the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light-independent reaction.
Which process is mostly driven by light energy?
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
How do plants use and change energy?
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.
What is the most abundant form of energy in a cell?
Eukaryotic cells use three major processes to transform the energy held in the chemical bonds of food molecules into more readily usable forms — often energy-rich carrier molecules. Adenosine 5′-triphosphate, or ATP , is the most abundant energy carrier molecule in cells.
Do plants convert energy into matter?
During photosynthesis, plants convert the sun's energy into chemical energy which is captured within the bonds of carbon molecules built from atmospheric carbon dioxide and water. ... Each year trees use the left-over carbon molecules to add to themselves, making themselves bigger in mass (size). Voila!
Do plants take in oxygen?
Most folks have learned that plants take up carbon dioxide from the air (to be used in photosynthesis) and produce oxygen (as a by-product of that process), but less well known is that plants also need oxygen . ... So plants need to breathe — to exchange these gases between the outside and the inside of the organism.
How do plant cells get energy?
In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose. In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.
What is photosynthesis class 6th?
Hint: Photosynthesis is the process by which green plants prepare their own food with the help of carbon-dioxide, water, chlorophyll and light. By this process the light energy is converted into chemical energy . Complete Answer: A.
What are the two main steps of photosynthesis?
The stages of photosynthesis
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle . Requires sunlight? Schematic of the light-dependent reactions and Calvin cycle and how they're connected. The light-dependent reactions take place in the thylakoid membrane.
Does photosynthesis produce ATP?
The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
What is the chemical reaction of photosynthesis?
Photosynthesis is a series of chemical reactions that convert carbon dioxide and water into glucose (sugar) and oxygen in the presence of sunlight.
