What happens during photosynthesis?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water , carbon dioxide , and minerals into oxygen and energy-rich organic compounds .
What is the chemical equation for photosynthesis?
6CO2 + 6H2O + Light energy → C6H12O6 (sugar) + 6O2 The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of the energy from the Sun, which the plant can either use or store for later. Imagine a pea plant.
What is the Ek of photosynthesis?

What are the reactants and products of photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What do plants need to perform photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).

What is the function of silica in photosynthesis?
They have mineralized cell walls (frustules) that contain silica and provide protection and support. In photosynthesis, light energy is converted to chemical energy, which is stored in the form of glucose (sugar). Inorganic compounds (carbon dioxide, water, and sunlight) are used to produce glucose, oxygen, and water.
What gas do plants take in for photosynthesis?
Plants, however, take in and use carbon dioxide gas. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.
What is the by-product of photosynthesis?
All green plants and a few other autotrophic organisms utilize photosynthesis to synthesize nutrients by using carbon dioxide, water and sunlight. The by-product of the photosynthesis process is oxygen.Let us have a detailed look at the process, reaction and importance of photosynthesis. What Is Photosynthesis in Biology?
What is the Order of photosynthesis in a plant?
Oxygenic photosynthesis begins with light absorption, followed by excitation energy transfer to the reaction centres, primary photochemistry, electron and proton transport, NADPH and ATP synthesis, and then CO 2 fixation (Calvin–Benson cycle, as well as Hatch–Slack cycle).
What did Joseph Priestley discover about photosynthesis?
Joseph Priestley (1776) showed, in elegant experiments, that plants produced ‘oxygen’ (then called de-phlogisticated air) needed by a mouse to live, whereas Jan Ingen-Housz (1773) convincingly established that light was necessary for photosynthesis.
