Plant tissue culture is a widely used procedure in plant biology in which organism is planted from the explants of the living plants in a nutrient medium under aseptic conditions. There are both advantages and disadvantages of plant tissue culture. Advantages: 1. To produce many copies of the same plants then which may be used to produce plants with better flowers‚ odors‚ fruits or any other properties of the plants that are beneficial to the human beings. 2.

ANIMAL TISSUES 1. Classify the animal tissues. On the basis of the function they perform‚ animal tissues are classified into four different types. They are: i) Epithelial tissue ii) Connective tissue iii) Muscular tissue iv) Nervous tissue 2. What are epithelial tissues? What are the characteristic features of these tissues? The covering or protective tissues in the animal body are called epithelial tissues. They also perform the functions of secretion and absorption
