Leaf function in plants form and structure


Leaf function in plants form and structure

We often encounter every day that plants around us turn out and that plants have a wide green color. Help yourself has a variety of shapes, some are elliptical and heart-shaped. 

There are also various kinds of leaf bones that are curved parallel to and are also pinnate. But friends, do you know the function of plant leaves? if friends don't know the function of these plant leaves, let's study together OK. Just read this article. 

Leaf function in plants 

Year is the most important part of the plant. Year has a role for the growth and development of plants, which are generally 6, as below.

The place of photosynthesis 

The first leaf function is the year it is used for the processing of food substances. The excretion of nutrients can be called photosynthesis. In this process, the processing of photosynthesis or plant food really needs water and carbon dioxide with the additional help of the sun. 

The water and carbon dioxide are converted into organic compounds or oxygen. This carburetor will also be a nutrient for plants and can also be used to make other compounds that are most needed from some of the results, carbohydrates can also be stored by plants during photosynthesis to be used as food reserves.

Therefore, the meaning of photosynthesis is the formation of carbohydrates, CO2 and water, with additional help from the sun, plants can do what is called photosynthesis because plants have cells that contain chlorophyll or can be called green leaf matter.

In the process of photosynthesis, the energy absorbed by chlorophyll can be converted into chemical energy which will be stored in the form of carbohydrates or other forms. Plants will also convert carbohydrates into protein, fat or other vitamins. These organic compounds can be used by plants and have benefits for grass-eating animals or humans.

As a respiratory organ 

The stomata that exist in this year have a function, namely as a place for gas exchange or respiration for plants to take place. The stomata will later take carbon dioxide from the air to become the basic material for photosynthesis and the result can release oxygen. 

You also need to know that in the process of photosynthesis, plants can only do this if you get enough sunlight and the presence of chlorophyll. Besides that, in the year part it turns out that chlorophyll is also found in the plant stem. for chlorophyll that is in special stems in plants whose leaves have a shape and function such as cactus and pine. 

Place of the transpiration process 

The years present in plants can be used in transpiration. When plants suddenly have excess or lack of water, there is something else, namely the cuticle on the leaf surface, which can do what is called evaporation and the plant tissue will pass through the stomata. 

The presentation occurs when a plant generally loses a lot of water through the leaves, it turns out that there are two types of transpiration in the plant, among others Stomata transpiration, that is, if the plant loses water directly through the stomata,

the water number up to 97% of the water in the plant is suddenly lost through stomatal transpiration Cuticle transpiration. Namely evaporation that occurs directly and through the epidermal cuticle.

 Vegetative reproduction tools 

The function of leaves in plants is that they are used for vegetative reproduction tools. This reproduction is the same as in the cocor duck plant which has and can form leaf shoots, namely adventitious shoots which will later grow on plant leaves.

When plants carry out the process of photosynthesis, they can be influenced by internal and external factors. The things that can affect photosynthesis are light, temperature, concentration and water.


If more and more chlorophyll is present in plant leaves, photosynthesis can take place very quickly, the formation of chlorophyll itself can and requires sunlight. That's why sprouts that are usually planted in the dark will not get chlorophyll properly. Sprouts will experience etiolation, which is very fast growth, higher or longer than those usually pale leaves because they do not contain chlorophyll.

Leaf age 

The most recent leaf function, namely the leaves can be influential in the photosynthesis process when the leaves are older, the so-called photosynthesis in ability will decrease because the old chlorophyll is left behind and the function of the chloroplasts itself has decreased. 

different from young leaves that are green after photosynthesis tends to be easier and tends to get more nutrients from old leaves. however old leaves contain a lot of chlorophyll to increase the age of the plant which can also cause a decline in the condition of the plant itself which can later cause the plant to die.
