Risks to the banking sector remain worryingly high and these have stayed elevated due to continuous deterioration in asset quality, low profitability and liquidity.There are various reasons for elevation of such risks such as -(a)GDP Slowdown(b)Relaxed lending Norms(c)Priority Sector Lending(d) Lack of Bankruptcy code.However various measures have been ndertaken in order to curb these.Some of them are as follows- (a)Government has launched Mission Indradhanush to make the working of public sector bank more transparent and professional in order to curb the menace of NPA in future. (b)Government has also proposed to introduce Bankruptcy code which will make it easier for banks to Recover the loans from the debtors. (c)Setting up a Joint Lenders’ Forum, prodding banks to disclose the real picture of bad loans, asking them to increase provisioning for stressed assets, (d)Introducing a 5:25 scheme where loans are to be amortized over 25 years with refinancing option after every five years, and (e)Empowering them to take majority control in defaulting companies under the Strategic Debt Restructuring (SDR) scheme. Way Ahead- (a)Improving credit risk management– This includes credit appraisal, credit monitoring, and efficient system of fixing accountability (b)Strengthen credit monitoring– Develop an early warning mechanism and comprehensive MIS(Management information system) can play an important role in it. (c)Enforce accountability- Till now lower ring officials considered accountable even though loaning decisions are taken at higher level. Thus sanction official should also share the burden of responsibility.

Thank you so much sir, your lessons are fabulous. Sir, i think "stomata" is also an important component of plants and that should also be covered.

  3. Plant tissues are of two main types, viz. 1 - Meristematic Tissue:-in which cells keep on 2- Permanent Tissue: the cells of meristematic meristematic tissue and permanent tissue. dividing are called meristematic tissue tissue divide to a certain extent, after that they become specialized for a particular function. This is called differentiation. After differentiation, the cells lose their capability to divide and the tissue becomes permanent tissue.


  4. Meristematic Tissue: Apical Meristem:- is present on root apex, stem apex, leaf buds and flower buds. They are responsible for growth in length, i.e. primary growth. Lateral Meristem is present along the side of the stem. They are responsible for growth in girth, i.e. secondary growth. . Intercalary Meristem: is present at the base of leaf or internodes. They are present on either side of the node.


  5. Simple Permanent Tissue is composed of similar types of cells. Simple permanent tissues are of three types, viz. parenchyma, collenchyma and sclerenchyma. 1) Parenchyma: have thin cell wall. They are loosely packed; with lot of intercellular spaces between them. Parenchyma makes the largest portion of a plant body, mainly works are packing material in plant parts. . The main function of is to provide support and to store food. . In some plant parts, parenchyma has chlorophyll as well. In that case, parenchyma carries out photosynthesis and is then termed as chlorenchyma. In aquatic plants, large air cavities are present in parenchyma. This provides buoyancy to the plant, and then the parenchyma is known as aerenchyma.

  7. Simple Permanent Tissue 2) Collenchyma: The cell wall is thickened at corners. Intercellular spaces are very few. Collenchymas provides some degree of structural rigidity with flexibility. Collenchymas is present in leaf stalk; below the epidermis. Due to this, the leaf talk can easily bend but does not break. 3) Sclerenchyma: The cell wall is highly thickened all around The cells are dead and intercellular space is absent. Sclerenchyma provides structural rigidity to plant parts. Bark and the coconut husk is composed of sclerenchyma. .

  10. Complex Permanent Tissue: is composed of different types of cells. Complex permanent tissues IS are of two types, viz. xylem and phloem. Xylem and phloem together make the vascular bundle in plants. Xylem: Xylem is composed of trachieds, vessels, xylem parenchyma and xylem fibres. The cells of xylem are dead; except the cells of xylem parenchyma. Trachieds and vessels are tubular structures and thus they provide a channel for conduction of water and minerals. Xylem fibre provides structural support to the tissue. Xylem parenchyma stores food. .
