Where do you get the food you eat everyday?
We depend directly and indirectly on tree or plants for our food.
So how do plants get their food? Green plants make their own food.
Green plants use water and carbon dioxide to prepare their food.
Photosynthesis
At the same time, raw materials are collected from the air and soil and mixed in the presence of sunlight. Because it occurs only in the presence of light, this process is called photosynthesis.
Let's see how photosynthesis works
Plants require a good supply of raw materials for photosynthesis.
The roots absorb water and minerals from the soil and carry it to the leaves.
Important organization of photosynthesis process
Another important organizer of photosynthesis is carbon dioxide.
When humans and animals breathe, they release carbon dioxide into the atmosphere. This carbon dioxide is absorbed by plants.
Carbon dioxide enters the leaves through these stomata pores in the atmosphere.
Carbon dioxide is present on the surface in the leaves of plants, which is filled with small holes called foramen.
How do plants make their food?
Plants need energy to prepare their food, this energy comes from the sun.
The leaves contain a natural green pigment called chlorophyll which absorbs sunlight.
In the presence of sunlight, water and carbon dioxide combine to produce carbohydrates and oxygen. As food, carbohydrates are transported to different parts of plants.
Plants do not require the oxygen produced so it is vented out into the atmosphere.
The oxygen exhaled is very valuable as used by all the animals for respiration. To make their own food, the plants reuse the carbon dioxide left outside and the process continues.
Photosynthesis equation
Water + carbon dioxide = carbohydrate and oxygen
Photosynthesis process
The plant requires air, water and sunlight for photosynthesis.
The roots absorb water and minerals from the soil.
Plants absorb carbon dioxide from the air.
Water and carbon dioxide combine to produce carbohydrates and oxygen.
Carbohydrates are transported to different parts of plants.
Oxygen is released into the atmosphere
