Question

list the steps of photosynthesis​

Answer 1

Answer:

The process of photosynthesis step by step

• During the process of photosynthesis, carbon dioxide enters through the stomata, water is absorbed by the root hairs from the soil and is carried to the leaves through the xylem vessels. Chlorophyll absorbs the light energy from the sun to split water molecules into hydrogen and oxygen.

• The hydrogen from water molecules and carbon dioxide absorbed from the air are used in the production of glucose. Furthermore, oxygen is liberated out into the atmosphere through the leaves as a waste product

• Glucose is a source of food for plants that provide energy for growth and development, while the rest is stored in the roots, leaves and fruits, for their later use.

• Pigments are other fundamental cellular components of photosynthesis. They are the molecules that impart colour and they absorb light at some specific wavelength and reflect back the unabsorbed light. All green plants mainly contain chlorophyll a, chlorophyll b and carotenoids which are present in the thylakoids of chloroplasts. It is primarily used to capture light energy. Chlorophyll-a is the main pigment.

Answer 2

Green plants make their own food by using carbon dioxide,water,in the presence of oxygen and with the help of chlorophyll is called photosynthesis. The process is as follows

•Water is taken from the roots of the plant, and it is transported to leaves of the plant.

•Carbon dioxide from air enter the leaves through pores called stomata. This diffuses the cell containing chlorophyll.

•Water molecule is broken down into Hydrogen and Oxygen with the help of sunlight.

•Hydrogen combines with Oxygen and Hydrogen to form carbohydrates.

Photosynthesis is represented by the following equation.

Photosynthesis equation:-

Co2 +H2O →sunlight/chlorophyll = C6H12O6+O2
