What is photosynthesis for class 10th?

What is photosynthesis for class 10th?

Question 10 (i) Photosynthesis: The process by which green leaves prepare their own food by using carbon dioxide and water in the presence of sunlight and chlorophyll is called photosynthesis.

What are the steps of photosynthesis Class 10?

The process of photosynthesis takes place in the following three steps:

  • • Absorption of light energy by chlorophyll.
  • • Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
  • • Reduction of carbon dioxide to carbohydrates.

What are the steps in photosynthesis?

The stages of photosynthesis

Stage Location Events
Light-dependent reactions Thylakoid membrane Light energy is captured by chloroplasts and stored as ATP
Calvin cycle Stroma ATP is used to create sugars that the plant will use to grow and live

What is life Process 10th?

Important life processes include nutrition, transportation, metabolism, respiration, reproduction and excretion, which help in the maintenance of living organisms. Life processes Class 10 is a detailed version of different processes carried out by plants and animals.

What is photosynthesis 10th standard?

Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials. Chlorophyll is a substance in all green plants, especially in the leaves.

What are the 7 steps in photosynthesis?

Terms in this set (7)

  • 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 are the 7 life processes of a human?

The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion. All of these processes are interrelated.

What kind of energy does a plant use for photosynthesis?

Photosynthesis is an autotrophic mode of nutrition by plants and some bacteria. 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. Basic raw materials for photosynthesis

What are the correct order of the terms in photosynthesis?

Rewrite the terms in correct order so as to be logical sequence with regards to photosynthesis. (a) Water molecules, photons, H⁺ and OH¯ ions, o2, Grana (b) Destarched plant, iodine added, washed in water, a leaf boiled in alcohol, placed in sunlight 5.

What should the temperature be for photosynthesis to occur?

Usually, carbon dioxide in the range of 300 – 400 PPM is adequate for photosynthesis. Temperature: For efficient execution of photosynthesis, it is important to have a temperature range between 25° to 35° C.

What are the three basic events of photosynthesis?

Photosynthesis can be split into three basic events. Rate of photosynthesis depends on many factors like light, carbon dioxide, water and chlorophyll. a) Light: Visible spectrum of the sunlight ranges from 380 to 750 nanometres in wavelength.
