Question : What are the differences between different types of pathogens ? Why same drug cannot be used for all the pathogens ?

Answer»

Solution :(1) Pathogens are of DIFFERENT categories of such as viruses, BACTERIA, protozoans, fungi or worms.
(2) Every pathogen has different mode of life. Viruses live inside host cells. Bacteria cannot live inside the host cells.
(3) But both viruses, bacteria and fungi multiply very quickly, while worms show slower multiplication.
(4) Different bacteria show similarity in their structure. Therefore, taxonomically, they are closely related to each other having similar life process. But viruses are not so.
(5) Therefore, drugs that block life processes in bacteria cannot be similarly effective against viruses or any other pathogen.
(6) MOREOVER, most of the antibiotic block the metabolic processes of bacteria and also dissolve their cell walls. Such drug MAY not act on viruses, protozoans or fungi.
(7) Thus, based on the body characters of each pathogen, different drugs are to be used for the TREATMENT.

Question : What are the advantages of composite fish culture?

Answer»

Solution :In a comosite fish clture method, a combination of live or six different fish species are reared in a single FISHPOND. Species are selected in such a way that they do not compete for food among them. Each one has different type of food habits. Therefore, food from all THEPARTS of the pond is utilized without having intr specific competition. e.g., Catla, Rohu, Mrigals, Carps are reared TOGETHER in composite fish culture method. CAtlas are SURFACE feeders, Rohus feed in the middle zone of the pond, Mrigals and Common Carps are bottom feeders, and Grass carps feed on the WEEDS. This increases the fish yield from the pond. Different varieties of fish are availale at the same time, with less expenditure.

Question : What are permanent tissues? Describe the different types of simple permanent tissue.

Answer»

Solution :Permanent tissues are those in which, growth has stopped either completely or for the time being At times, they become meristematic partially or wholly. Permanent tissues are of two TYPES namely (i) simple tissue and (ii) complex tissue.
Simple tissue
Simple tissue are homogeneous-composed of structurally and functionally similar cells eg., Parenchyma, collenchyma and Sclerenchyma.
(i) Parenchyma
Parenchyma are simple permanent tissue composed of living cells. Parenchyma cells are thin walled, oval, ROUNDED or polygonal in shape with well developed spaces among them, In aquatic plants, Parenchyma possesses intercellular air spaces, and is named as Aerenchyma. When exposed to light, parenchyma cells may develop chloroplasts and are known as CHLORENCHYMA.
Functions: Parenchyma may store water in many succulent and xerophytic plants. it also serve the function of storage of food reserves, absorption, buoyancy, secretion etc.
(ii) Collenchyma
Collenchyma is a living tissue found beneath the epidermis. cells are elongated with unevenly thickned non-lignified walls. Cells have rectangular oblique or tapering ends and persistent protoplast. They possess thick primary non-lignified walls
Functions: They provide mechanical SUPPORT for growing organs.
(iii) Sclerenchyma
Sclerenchyma consists of thick walled cells which are often lingnified, sclerenchyma cells do not possess living protoplasts at maturity. Sclerenchyma cells are grouped into (i) FIBRES and (ii) sclereids.
Fibre are elongated sclerenchymatous cells, usually with pointed ends. Their walls are lignified Fibre are abundantly found in many plants. the average length of fibres is 1 to 3 mm, however in plants like linum usitatissimum (flax) cannabis sativa (hemp) and corchorus capsularis (jute) fibres are extensively longer ranging from 20mm to 550 mm.
