              Plants are subject to attack and infection by a remarkable variety of symbiotic species and have evolved a diverse array of mechanisms designed to frustrate the  potential colonists. These can be divided into preformed or passive defense mechanisms  and inducible or active systems. Passive plant defense comprises physical and chemical  barriers that prevent entry of pathogens, such as bacteria, or render tissues unpalatable or toxic to the invader. The external surfaces of plants, in addition to being covered by an epidermis and a waxy cuticle, often carry spiky hairs known as trichomes, which either prevent feeding by insects or may even puncture and kill insect larvae. Other trichomes are sticky and glandular and effectively trap and immobilize insects. If the physical barriers of the plant are breached, then preformed chemicals may inhibit or kill the intruder, and plant tissues contain a diverse array of toxic or potentially toxic substances, such as resins, tannins, glycosides, and alkaloids, many of which are highly effective deterrents to insects that feed on plants. The success of the Colorado beetle in infesting potatoes, for example, seems to be correlated with its high tolerance to alkaloids that normally repel potential pests. Other possible chemical  defenses, while not directly toxic to the parasite, may inhibit some essential step in the establishment of a parasitic relationship. For example, glycoproteins in plant cell walls may inactivate enzymes that degrade cell walls. These enzymes are often produced by bacteria and fungi.
            Active plant defense mechanisms are comparable to the immune system of  vertebrate animals, although the cellular and molecular bases are fundamentally different. Both, however, are triggered in reaction to intrusion, implying that the host has some means of recognizing the presence of a foreign organism. The most dramatic example of an inducible plant defense reaction is the hypersensitive response. In the hypersensitive response, cells undergo rapid necrosis ― that is, they become diseased and die ― after being penetrated by a parasite ; the parasite itself subsequently ceases to grow and is therefore restricted to one or a few cells around the entry site. Several theories have been put forward to explain the bases of hypersensitive resistance.

World Wildlife Fund (WWF) safeguards hundreds of species around the world, but we focus species attention on our flagship species: giant pandas, tigers, endangered whales and dolphins, rhinos, elephant, marine turtles and great apes. These species not only need special measures and extra protection in order to survive, they also serve as “umbrella” species: helping them helps numerous other species that live in the same habitats.
In addition to our flagship animals, we work to protect numerous species in peril around the world that live within our priority eco-regions. Large predators like snow leopards and grizzly bears, migratory species like whooping cranes and song birds, and a host of other species facing threats also benefit from WWF’ s conservation efforts. Our wildlife trade experts at “traffic” work to ensure that trade wildlife products, doesn’t harm a species, while also fighting against illegal and unsustainable trade.
WWF is known for acting sound science. Science leads and guides us strategies and approaches, from the way to restore tigers in viable, breed population to decide which areas need protection the most.
How many species do we pay much attention to?
A.5
B.8
C.7
