What is photosynthesis very short answer type question?
Photosynthesis is the process by which plants and other things make food. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars that the cell can use as energy. As well as plants, many kinds of algae, protists and bacteria use it to get food.
What is photosynthesis one word answer?
Photosynthesis is the process by which plants, algae and some bacteria use sunlight, carbon dioxide and water to prepare their food. This is a biogeochemical process in which light energy is converted into chemical energy.
What is the photosynthesis formula?
The process of photosynthesis is commonly written as: 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2 . 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.
Why is it called photosynthesis?
This chemical energy is stored in carbohydrate molecules , such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (φῶς), “light”, and sunthesis (σύνθεσις), “putting together”. In most cases, oxygen is also released as a waste product.
What are the 7 steps of photosynthesis?
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent. ...
- Step 5-Light independent. ...
- Step 6-Light independent. ...
- calvin cycle.
What stomata do?
Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.
Does photosynthesis occur at night?
Photosynthesis doesn't occur at night . When there is no photosynthesis, there is a net release of carbon dioxide and a net uptake of oxygen. ... the rate of photosynthesis is higher than the rate of respiration. there is a net release of oxygen and a net uptake of carbon dioxide.
What is photosynthesis best answer?
Photosynthesis is the process by which plants use sunlight , water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is photosynthesis class 8th?
Photosynthesis is the physico-chemical process by which plants can convert light energy into chemical energy , in the form of carbohydrate from simple inorganic substances like atmospheric carbon dioxide and water. Photosynthesis requires carbon dioxide, sunlight, water and chlorophyll as its basic raw materials.
What is photosynthesis for kids?
Photosynthesis is the process in which green plants use sunlight to make their own food. ... Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars. The plants use some of the sugars and store the rest. The oxygen is released into the air.
What is photosynthesis example?
An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow . The water from the leaves evaporates through the stomata, and filling its place, entering the stomata from the air, is carbon dioxide. Plants need carbon dioxide to make food.
What is the first step in photosynthesis?
The first step of photosynthesis is the absorption of light energy and the loss of electrons from chlorophyll . Photosynthesis is a process by the plant to produce food by absorbing light of a certain wavelength and used to convert water and carbon dioxide and minerals into oxygen-rich and energy-rich organic compounds.
What is the importance photosynthesis?
Photosynthesis is the process of plants transforming CO2 to O2 , which almost all living things need to live. So the importance of photosynthesis is that without it, there would be no life . Most likely not many plants either, since living beings produce CO2 which the plants need.
