AUTOTROPHSTHE PLANTS THAT MAKE THEIR OWN FOOD IS KNOW AS AUTOTROPHS.THE GREEN PLANTS PREPARE THEIR OWN FOOD WITH THE HELP OF CARBON DIOXIDE AND WATER TAKEN FROM THE ENVIORNMENT.THEY USE CHLOROPHYLL A GREEN COLOURED PIGMENT IN PRESENCE OF SUNLIGHT FOR THE MANUFACTURED OF FOOD.THIS PROCESS IS KNOWN AS PHOTOSYNETHIS .( PHOTO=LIGHT;SYNETHESIS=TO COMBINE ).THE PROCESS OF PHOTOSYNTHESIS CAN BE SUMMERSIED AS UNDER CARBON DIOXIDE + WATER GLUCOSE+OXYGENIMAGE

IMPORTANCE OF PHOTOSYNTHESISIT IS THE MOST IMPOLRTANT BIOLOGICAL PROCESS ON WHICH ALL LIVING ORGANISMS DEPEND DIRECTLY OR INDIRECTLY FOR FOOD.THIS PROCESS MAINTAINS THE BALANCE OF CARBON DIOXIDE AND OXYGEN IN THE ENVIONMENT.IT PROVIDES US OXYGEN FOR BREATHING. NOTE: PHOTOSYNTHESIS TAKES PLACE MOSTLY IN THE GREEN LEAVES OF PLANTS LIKE CACTUS,IT TAKES PLACE IN THE GREEN FLESHY STEM AS THE LEAVES ARE REDUCED TO SPINES TO REDUCE LOSSOF WATER BY TRANSPIRATION.HETERTROPHIC PLANTSPARASITESEG; CUSCUTA, DODDERSAPROPHYTESEG; FUNGI,BACTERIAINSCTIVOROUS PLANTSEG; PITCHER,FLYTRAPS

PARASITES PLANTA parasite is an organism that depends on another organism, known as a host, for food and shelter. As an example, tapeworms live in the digestive system of a large variety of animals. The tapeworms have no digestive system of their own, but absorb nutrients through their skin from partially digested food as it passes through the host.A parasite usually gains all the benefits of this relationship. In contrast, the host may suffer from various diseases, infections, and discomforts as a result of the parasitic attack. In some cases, however, the host may show no signs at all of infection by the parasite.

SAPROPHYTESsaprophyte , any plant that depends on dead plant or animal tissue for a source of nutrition and metabolic energy, e.g., most fungi (molds) and a few flowering plants, such as Indian pipe and some orchids. Most saprophytes do not produce chlorophyll and therefore do not photosynthesize; they are thus dependent on the food energy they absorb from the decaying tissues, which they help to break down.

INSECTIVOROUS PLANTS

Sponsored LinksCarnivorous plants are plants that capture, kill, and digest animal organisms. Since carnivorous plants usually live in areas where the soil quality is poor, they must supplement their diets with nutrients gained from digesting insects. These plants have developed specialized leaves that work to lure and then trap unsuspecting insects.

SYMBIOTIC PLANTSSymbiosis is a biological relationship in which two species live in close proximity to each other and interact regularly in such a way as to benefit one or both of the organisms. When both partners benefit, this variety of symbiosis is known as mutualism. The name for a situation in which only one of the partners benefits is far more well known. Such an arrangement is known as parasitism, and a parasite is an organism that obtains nourishment or other life support from a host, usually without killing it. By their very nature, parasites are never beneficial, and sometimes they can be downright deadly.IMAGES
