Important Topic of Biology: Tissue Culture

Introduction

Tissue culture is the process by which plant pieces are grown and planted in a laboratory. Many times organs are also used in tissue culture. The media used for cultural growth are broth and agar.

    This process is also known as micropropagation. It has been shown to be beneficial in producing disease-free plants and increasing crop yields in developing countries. It only needs a sterile workplace, a heat exchanger, trained staff, and a crèche.

    Palm oil, bananas, eggplant, pineapple, rubber tree, tomato, sweet potato to produce tissue culture in developing countries.

    Types of Tissue Cultures

    The following are the different types of tissue repair methods:

    • Seed Culture: In this tradition, annotations are obtained from an in-vitro plant and are incorporated into a laboratory where they are multiplied. Explorer should be sterilized to protect it from tissue damage.
    • Culture of the embryo: This includes the development of embryonic invitro. As a result, the embryo is separated from the living organism. In both cases, the mature or the immature embryo can be used in this process. Mature embryos can be obtained from mature seeds. Unripe embryos are found in seeds that have failed to germinate. The ovule, seed or fruit is already sterilized, therefore, it does not need to be cleaned again.
    • Callus Culture: The callus is a random, divisive set of cells. When explosives are properly propagated, callus is detected. Callus growth is followed by limb division. The culture is grown in a gel-like environment made up of agar and certain nutrients needed for cell growth.
    • Body Culture: In this case, any part of the plant such as the shoot, the leaf, can be used as a plant. Many methods can be used for organ culture, such as plasma clotting method, ransom method, the grid method, and agar gel method. This method is used to preserve the structure and functions of an organism.
    • Protoplast Culture: It is a cell without a cell wall. The protoplast can be propagated using a hanging method, or micro-culture chambers. In the protoplast culture, many stages can be observed: cell wall development, cell division, regeneration of the whole plant.

    Other Types

    • Pollen Culture
    • Anther Culture
    • Single Cell Culture
    • Suspension of Culture
    • Somatic Embryogenesis

    Measures of Tissue Culture

    The steps for Tissue Culture are given below:

    • Phase One
      At this stage, the tissue is initiated in the culture. Tissue tissues are detected, introduced and disinfected to prevent the process from any contamination.
    • Repetition Phase
      At this stage, the sterile plant is introduced into the area made up of growth controls and proper nutrients. They are responsible for cell duplication. This isolated number of cells is known as the callus.
    • Root Construction
      The roots begin to grow. Plant growth hormones were added to initiate root formation. As a result, we get perfect plantlets.
    • Shoot Formation
      Vegetable growth hormone production is added and growth is observed throughout the week.
    • Familiarity
      When a plant begins to grow, it is transferred to the greenhouse to grow under controlled natural conditions. Eventually it is transferred to institutions to grow under natural conditions.

    Benefits of Tissue Culture

    Here are the various benefits of the tissue Culture technique:

    • Plantlets are found in a very short time with a small amount of plant tissue.
    • Newly produced plants are disease-free.
    • Crops can be planted all year round, regardless of the time of year.
    • A large area is not required for the growth of plants through the tissue culture process.
    • The production of new varieties in the market is fast.
    • This process is used for the production of ornamental plants such as dahlia, chrysanthemum, orchids, etc.

    The Importance of Tissue Culture

    Tissue culture is very important in biology because of its wide range of applications.

    • Both plant and animal tissues can be used for farming. For example, animal tissue culture helps to preserve an organ or tissue.
    • Crop tissue culture may be used to modify a plant’s genes or simply increase its yield. plant cells can be genetically modified to produce plants with desirable traits.
    • This process utilizes the plant’s ability to regenerate tissues quickly. It produces its own copies known as clones.
    • It is a way of producing plants quickly without any bulbs, seeds or bulbs.
    • It also helps to conserve biodiversity through the production of endangered plants.

    Tissue culture is the growth of tissue or cells in a synthetic environment that is different from the parent. This process is also called micropropagation. This is usually facilitated by the use of a liquid, a little hardening, or a solid growth medium, such as broth or agar.

    FAQ’s

    Q. How are natural plants produced locally?

    Ans: Natural plant products are used as agricultural chemicals, medicines and food additives. At the industrial level, cell culture is used as an effective technology for producing high quality natural plant products. Pfizer Company made great strides in the 1950s and 1960s to develop plant cells in a liquid (culture setting), similar to microbe culture, to make natural plant products as one of the complete plants. For a larger culture of plant cells, different types of bioreactors have been developed.

    Q. Describe the modern use of tissue culture?

    Ans: In current usage, “tissue culture” refers to the in vitro development of cells from multicellular tissue. These cells can be the primary cells from a donor or an immortal cell. Cells immersed in the cultural media provide all the nutrients and energy sources needed for cells to survive. As a result, “tissue culture” and “cell culture” are often used interchangeably in a broader sense. The literal definition of “tissue culture,” on the other hand, is related to the implantation of tissue fragments, also known as implant culture.

    Q. What is the use of Tissue Culture?

    Ans: The traditional tissue method is widely used in the production of ornamental plants such as orchids, dahlia, carnation, chrysanthemum, etc. Plant production in the form of tissue culture is also known as micropropagation because of the small number of plants used. This approach is useful in poor countries trying to increase agricultural productivity, independent local farmers seeking consistent quality, and businesses looking to make clones of some kind for profit.
