Photosynthesis

                            hello kids do you know how plants make

their own food no well this video

elaborates the process of photosynthesis

by which plants make their own food

photosynthesis is the process used by

plants to make their own food or in more

complex terms it is the conversion of

light energy into chemical energy by

plants this chemical energy is used by

the plants for growth and nourishment

photo means light and synthesis means

putting together in greek when humans

cook food some essential things are

required including fire water vegetables

etc similarly to make their food plants

also need some essential factors

including light water nutrients soild

etc plants get light from the Sun water

from the ground and carbon dioxide from

the air all of these factors including

air water carbon dioxide and sunlight

together help plants turn out their own

food plants have tubes called xylem

located in the stems through which the

water from the ground is sucked into the

leaves this system works similar to

humans sucking liquids through a straw

the xylem is spread throughout the

different parts of the plant including

the stem branches and all the way up to

the leaves the xylem transports vital

nutrients to the entire plant xylem Xin

the plant are like blood vessels in the

human body that act as an important

means of transportation of water and

nutrients leaves on the plant have pores

very similar to the pores on the skin of

our bodies these pores are called

stomata the stomata are responsible for

the exchange of gases the carbon dioxide

present in the air which is responsible

for photosynthesis enters the plant

through these stomata

oxygen also comes out through the

stomata leaves have important cells

called mesophyll cells these cells

contain a green color component called

chloroplasts this chloroplast is

responsible for the green color of

plants and leaves once the carbon

dioxide and the water reach the

chloroplasts in the residence of

sunlight the process of photosynthesis

starts to take place the following

reaction takes place in the leaves of

the plant during photosynthesis carbon

dioxide plus water in the presence of

light energy results in oxygen plus

glucose or carbohydrates the products

formed are glucose and oxygen

carbohydrates which are a form of

glucose are synthesized from carbon

dioxide and water glucose is used by the

plants for their growth some of the

glucose is used immediately and the

extra glucose which is not used is

stored in the form of starch in the

leaves some amount of this extra glucose

is also stored in the roots of the

plants this extra glucose is used to

perform photosynthesis when there is no

sunlight oxygen is given out into the

air through the stomata in the process

of photosynthesis the oxygen that is

released is used by human beings to

breathe during their respiration process

ever wondered why this process is called

photosynthesis well the word

photosynthesis is a combination of two

Greek words photo and synthesis photo

means light in Greek and synthesis means

putting together or combining hence

photosynthesis literally means combining

water or carbon dioxide in the presence

of light so the essential factors for

photosynthesis to take place include

sunlight water and carbon dioxide under

water photosynthesis takes place at a

slower pace than the normal

photosynthesis this is because energy

from the Sun is absorbed by the water

layers and only some amount of energy

actually reaches the plant there are

some plants which don't need the process

of photosynthesis to grow such plants

and include mushroom venus flytraps etc

mushrooms get their food from the ground

and from their surrounding areas venus

flytraps

trap and catch small insects which come

near the leaves and eat them don't
