The smallest part of living things is the cell. Our bodies and other living things can be shaped like today is a combination of many cells so it is perfect as we are today. We will discuss a little about cell tissue in plants.
Plants have an important role for life on this planet. Whether we realize it or not, the presence of plants around us is an important part of the life cycle. Without plants, life on this planet would not exist.
You can imagine where all the air and water came from. The foods we eat every day such as rice, vegetables, and various other processed foods depend on plants as the main producers.
So do not be surprised if we are obliged to know and study plants so that the life of humans on this planet can still exist.
We need to admit that we are very dependent on plants for everything. Without their presence there will never be fresh oxygen that we can breathe and fresh clean water to quench the thirst in the throat.
Plant Tissue
Cells are the smallest constituent of living things that are owned by plants, animals, and humans. They all have cells as their constituents. These cells unite and combine to form a network.
The tissue will also unite again to form an organ and these organs unite with each other to form the form of a creature, namely a plant like the tree we see today. Broadly speaking, the existing tissue in plants is divided into two types, namely: tissue, namely meristem tissue (young) and adult tissue.
Meristematic
Network Meristematic tissue is a network that will continuously divide and has a high enough totipotency ability to form other tissues, namely adult tissue. Meristem network itself is divided into two parts, namely as follows.
1. Primary Meristem Network
The primary meristem network which is part of the meristem network has several characteristics so that we can easily identify and study it. The following characteristics are possessed by this tissue, namely:
It is the youngest organ in plants
- Meristem tissue is the result of continued development of plant growth, namely embryonic or shoot
- Has the ability to divide continuously and elongated and is a constituent of adult tissue
- Auxin which is able to make this tissue to grow lengthwise
Located at the ends of the stems and roots
The growth process in primary tissue is called primary growth
2. Secondary Meristem Network
Secondary meristem network is also part of the meristem network has several characteristics so that we can easily know and learn about it.
The following characteristics are possessed by this tissue, namely:
- Derived from primary meristem tissue
- Secondary meristem tissue belongs to mature tissue with the ability totipotent to develop again
The growth that exists in this tissue is better known as secondary growth tissue , while adult tissue is a tissue that continues to divide but does not have a high totipotency to form other tissues. Adult tissue consists of several other tissues.
Some of these adult networks are as follows.
1. Epidermal tissue
Epidermal tissue is the outermost tissue of a plant which always performs the division process so that it has the following characteristics, among others:
Located at the outermost part of the plant
- Ahich is very tight so that there is no space between cells with each other
Has a shape like a beam
Can be modified according to the function of the plant cell
Epidermal tissue is the outermost tissue of the plant so it has a variety of functions that are quite important.
Some of the functions possessed by the epidermal tissue are as follows.
- As a protector from external dangers to the existing tissue in it
- Functions as a way for water to enter the plant
- As a place for water to evaporate when the water content in the plant is excessive
2. Parenchymal tissue
Parenchymal tissue is a network that is commonly found in plants and has not yet undergone differentiation. This tissue is usually used as a place to store non-structural carbohydrates and water.
Parenchyma tissue is also known as ground tissue. This tissue can be found in plants in the bark, root bark, fruit flesh, and endosperm, as well as leaves.
3. Supporting Network
Supporting tissue is a network that has a function as a support or reinforcement in plants. This tissue consists of two types of tissue, namely collenchyma tissue and sclerenchyma tissue.
4. Transport Network
As the name implies, this network has a function as a carrier of water and all the solutions needed by plants. Transport tissue is also known as vascular tissue because it uses a vascular or vascular system as a transport system.
5. Cork tissue
Cork tissue is a tissue that exists in plants with a function to protect other tissues so as not to lose so much water. This can be done because the nature of the cork cell itself has water-resistant properties.
The Importance of Studying Plant Tissues
Studying the science of plant tissues is important enough to serve as a study. Broadly speaking, the tissues that exist in plants are as previously discussed. However, for more details, you can read the book on biology that was taught in school in the past.
As a human being who in his daily life is very dependent on the existence of plants as producers in the life cycle on this planet, it is very natural to be familiar with the ins and outs of these producers. Thus, the possibility of preserving the existence of these producers can be maintained for all time.
Keeping plant life on this planet earth is the same as maintaining human life itself. We as living beings always depend on plants from food and the air we breathe comes from plants.
If one day the plant becomes extinct, it is certain that humans will also become extinct because even the most sophisticated technology is currently still not able to produce oxygen as plants produce oxygen for us.
Therefore, it is appropriate for us to thank the researchers and inventors who have been willing to sacrifice their time and thoughts in observing these plants.
With a fairly basic knowledge of plant cell tissue, it is hoped that we can continue to preserve plants on this earth. There are so many types of plants that exist in the world and all have the same cell tissue.
Thus the steps to develop it will become easier. Hopefully with this existing knowledge, it will not only become a theory but also be able to support us in the field for the realization of a better life.
