La FOTOSÍNTESIS explicada: etapas, fórmula, productos, funciones
Introduction to Photosynthesis
In this video, the process of photosynthesis is explained, including its stages, formula, products and types. The importance of chlorophyll in the process is also discussed.
What is Photosynthesis?
- Photosynthesis is a chemical process by which plants convert inorganic matter into organic matter from sunlight.
- Chlorophyll gives plants their characteristic green color and has the ability to transform sunlight into energy necessary for photosynthesis.
- Photosynthesis fulfills fundamental functions for the existence and preservation of life on Earth.
Functions of Photosynthesis
- Generates oxygen that living beings use to breathe
- Transforms solar energy into chemical energy
- Sustains biomass
Formula of Photosynthesis
- The chemical formula for photosynthesis is 6 H2O + 6 CO2 + light = C6H12O6 + 6 O2
- Six molecules of water, six molecules of carbon dioxide and solar energy are required for one molecule of glucose or sugar and six molecules of oxygen to be produced.
Stages of Photosynthesis
Absorption
- Roots collect water and mineral salts from the earth forming crude sap.
Circulation
- Raw sap rises up the stem to reach leaves.
Light Phase
- Leaves absorb carbon dioxide from atmosphere mixing with raw sap and solar energy.
- ATP molecule is made during this phase which stores energy.
- This phase requires sunlight.
Dark Phase
- Sunlight is not required.
- Energy stored during light phase is used to synthesize sugars, release oxygen into the atmosphere and fix carbohydrates.
Types of Photosynthesis
- Photosynthesis is classified into two types: Oxygenic and Anoxygenic or bacterial.
- Artificial photosynthesis aims to reproduce in the laboratory the photosynthetic processes of plants.
Products of Photosynthesis
- The products of photosynthesis are organic matter that results from the process vital for survival of living beings.
Factors Affecting Photosynthesis
In this section, the factors affecting photosynthesis are discussed.
Temperature Limitations
- The rate of photosynthesis increases with temperature up to a limit of 30 degrees Celsius.
- At higher temperatures, the rate of photosynthesis does not increase.
Carbon Dioxide Concentration
- The concentration of carbon dioxide in the environment affects photosynthesis.
- Higher concentrations of carbon dioxide result in higher rates of photosynthesis.
