Pomoto and Raphano-brassica are notable examples of man-made crops which have been developed with the help of protoplast fusion. They are made up of cells separated by non-living material, which is called an extracellular matrix. In invertebrates, both physical and chemical coordination are performed by the same tissues, because the nervous tissues also serve as hormone sources.
Embryologists have often classified tissues on the basis of their origin in the developing embryo; i. Epithelium The epithelial tissues are formed by cells that cover the organ surfaces such as the surface of skinthe airwaysthe reproductive tractand the inner lining of the digestive tract.
Steno form the basic structural unit of bone. The main drawback of embryo culture is that it is applicable to those distant crosses where crossing is possible and problems are related to post fertilization.
Somatic hybridization consists of several steps, viz: Muscle fiber have the ability to contract and producing movement or force. There are several uses of somatic hybridization in plant breeding. Propagules are small plants developed by micropropagation.
The most important reproductive tissues are the gonads ovaries and testeswhich produce the gametes eggs and sperm, respectively. There are basically two types: Hyaline cartilage tissue specimen was also observe under light microscope.
This tissue covers all organismal surfaces that come in contact with the external environment such as the skinthe airways, and the digestive tract.
As in the previous Lab, the slides were already prepared and no work apart from observing through the microscope, identifying and drawing the results, was to be done.
Protoplasts are naked cells or cells without cell wall. Some common kinds of epithelium are listed below: Only resistant or tolerant cells will survive in such solution. Haploids have been developed in more than plant species by anther culture technique.
Somatic embryoids may develop in vitro through embryogenesis. Micropropagation can be used for rapid multiplication of crop plants which are difficult to propagate sexually or those vegetatively propagated species in which rate of multiplication is slow. The variation which is observed among the plants which are regenerated from gametic culture is called gametoclonal variation.
Disease resistant somaclones have been isolated in several crops like sugarcane, potato, tobacco and ornamental plants.
DISCUSSION Tissues are made up of cells. Classification of tissue depends on their structure. Each kind of tissue is composed of cells with characteristic sizes,shapes and arrangements and each type of tissue is specialised to perform a specific function.
Project Report # 1. Meaning of Plant Tissue Culture: Growth of living plant tissues in a suitable culture medium (in vitro) is known as plant tissue culture. II.
Introduction Apart from the bone and cartilage, the rest of the specialized connective tissues are divided into 4.
Muscle tissue, Adipose tissue, Nervous tissue and Blood tissue. 1. Muscle tissue. It is in charge of the contractive action or movement of the body. It can be attached to /5(). Epithelial tissue can be divided into simple epithelium, stratified epithelium and Staffordshire epithelium. Epithelial tissue specimen that is observed under light microscope are Sequestration’s epithelium, Simple columnar epithelium, Simple cuboids epithelium.
Connective tissue ends structures together, form a framework and support for organs and the body as whole, store fat, transport substances, protects against disease and help repair damaged tissue. When human bone tissue specimen was observed the structure of lamellar.
